"/obj/ info + configure" is actually a convenience method to allow to + write o1 info configure instead of o1 info lookup configure + syntax -2008-11-02 - * Release of XOTcl 1.6.2 + package nx::class-method: + - convenience package similar to nx::plain-object-method + - allow for usage "C class method ..." in addition to "C object + method". + - made warnings configurable via nx::configure + class-method-warning on|off + - completed coverage and test cases -2008-11-01 - * added command ::xotcl::finalize + package nx::plain-object-method: + - made warnings configurable via nx::configure + plain-object-method-warning on|off + - completed coverage and test cases - This command has the only purpose to delete all objects and classes - of an interpreter in a multi-threaded environment at a safe time. +2013-05-30 Gustaf Neumann - Background: when XOTcl is used in a threaded environment such as - for example in AOLserver, one has to take care that the deletion - of objects and classes happens in a safe environment, where the - XOTcl destructors (destroy methods) are still able to - run. Without ::xotcl::finalize the deletion happens in - Tcl_FinalizeThread(), after thread cleanup (where e.g. the - thread local storage is freed). This can lead to memory leaks in - AOLserver, which allocates e.g. some structures on demand, but - since this happens after cleanup, it will leak. A simple ns_log - in a destructor might lead to this problem. The solution is to - call ::xotcl::finalize in the "delete trace" in AOLserver (as it - happens in OpenACS). + nsf.c + - fixed potential infinite loop in pattern matching for + precedence lists + - cget: make error message closer to tcl conventions + - extended regression test - Note, that ::xotcl::finalize is not intended for application programs. +2013-05-29 Gustaf Neumann - * some code cleanup + - adapt to object methods + - prevent default value checking, when it is determined by a command + - completed coverage if plain-object-method.tcl + - provide warnings via plain-object-method.tcl via "nsf::log warn ..." -2008-10-17 +2013-05-28 Gustaf Neumann - * handle nonposargs in method "copy" properly + - renamed initblock parameter from __initcmd to __initblock + - renamed nsf::configure parameter from "keepinitcmds" to + "keepcmds" - * extend regression test for copy + - saving "keepcmds" in an associative array named + "__cmd(/parameternName)" to allow saving of multiple + parmeters with less name clash danger (when application + stays away from variables stating with double underscore) - * added " mixinof -closure ?pattern?" - Query the objects for which is used as a per-object-mixin - (directly or indirectly) + nx.tcl: + - removed "info is .." since it might raise more questions + than it solves - * extended regression test for mixinof + - changed enumeration values for "-source" in + "info lookup methods" + "info lookup slots" + "info methods" + "info slots" + from + "all|application|baseclasses" + to + "all|application|system" + for consistency with "nsf::my" and "nsf::dispatch" which uses + "-system" as well - * updated documentation +2013-05-26 Gustaf Neumann -2008-09-11 - * Implement proper downgrading of Classes to Objects: + Traits: + - changed from traits-as-objects to traits-as-classes. This + allows for higher orthogonality of traits and class definitions + and allows in principle traits for object-specific methods (not + fully implemented/tested) + - fixed property/variable inheritance in traits. + - remove spurious debug line - In cases where a class ::C is created, which is later downgraded - to an object ::C (either via "::C class ::xotcl::Object" or via - "::xotcl::Object ::C"), earlier versions of XOTcl were to - liberal. The major problem is to invalidate all places, where - ::C might be used as a class, and were only classes are allowed - (e.g. mixin chains, precedence orders). + Cleanup of nsfAPI.decls + - remove unneeded enumeration types + - use "typeName" to shorten reported names of parameters + - use camel case for reported names - The new version does not allow downgrading via the class method - and does a destroy/create instead of a recreate when a - same-named class existed before. + - changed ::nsf::parametersyntax(..) to + ::nsf::parameter::syntax(..) - * reset mixin order for per-object mixins, when the superclass - of a class is deleted, which is used as per-object mixin + - xotcl2: adjusted manual parameter syntax entries to new conventions - * extended regression test - * Updating and improving documentation +2013-05-24 Gustaf Neumann -2008-06-24 - * Release of XOTcl 1.6.1 + - added implementation for slots with traces+types for classes + - exception for incorrect defaults are thrown during slot creation -2008-06-23 - * remove pattern argument from "info class" - * additional argument for "info precedence": "-intrinsic" - Syntax: - info precedence ?-intrinsic? ?pattern? - If "-intrinsic" is specified, only the classes of the - superclass type hierarchy are returned. Otherwise, - the precedence contains mixin classes as well. - * Check results for guards to be boolean instead - of int (now, guards are allowed to return e.g. "true") + - extended nsf::is, added parameter + * ?-configure? -- accept configure parameter options + * ?-name /name/? -- provide a parameter name for error message -2008-05-30 - * updating language reference + - simplified nx.tcl by using new nsf::is + - extended regression test - * Fix contents for %proc in forwarders in cases, - where the forwarder was called via next and - the argument list for next was provided. - Previously, "next" was used for %proc. + - added partly implementation for slots with traces+types for + classes -2008-05-28 - * make "info (inst)?forward -definition name" more robust (provide an - error message, if is not given - * New info subcommands "info parametercmd" - and "info instparametercmd" - * export *parametercmds in Serializer, use "-noinit" on slots as well + - fixed cases, where valuechangedcmd (and the other traces) did + not work with "configure" method.

The trailing argument of the + configure parameters (used e.g. for scripted object/class + definitions) is now of type "cmd".

The new xotcl obj var tables do not operate with - that. E.g.: - Object instproc vwait {varName} { - [self] instvar $varName - ::vwait [list $varName] - } - would wait for a global variable varName ... though: - Object instproc vwait {varName} { - [self] requireNamespace - ::vwait [self]::[list $varName] - } - should work ... - * xotcl.c: info classparent now returns object name of class, not - ::xotcl::classes*** - * xotcl.c: new method "objeval" on Object. It executes an command - in the scope of an object. This is an important convenience - method because something like: - Object instproc lappend {varName args} { - [self] instvar varName - eval ::lappend [list $varName] $args - } - is problematic if the object has a namespace and varName is an - array element ... then Tcl does want to upvar it (was also - present in all earlier xotcl versions ... we have used an - instvar alias then). Now we can do: + - better to let file classify this file as latex than C++ - Object instproc lappend {varName args} { - [self] objeval [concat ::lappend [list $varName] $args] - } - This is easier an faster than using an alias ... -2001-09-16 Uwe Zdun - * predefined.xotcl: - - new method "trace" on Object ... simple forwarder to tcl's trace - - eliminated "cset" on Object and from the distribution, seems to - be nearly unused - * whole distr: - - replaced direct namespace variable accesses with [self] or - instvar accesses. Here's what I did: - (a) grep for <[self]::> - (b) grep for plus <::> together in one line - (c) grep for <}::> to get e.g. ${a}::b - that should find most occurrences of variable namespace access, - except for direct accesses like: set y::x, where y is an object - name and c a variable to be set. + - removed c++ mode -2001-09-15 Uwe Zdun - * xotcl.c: - - Namespaces of objects are now created only on demand, - that is when: - - obj proc is created - - obj command is created with XOTclAddPMethod - - child is created on the object - Note that this is a prominent change. Especially it saves a - significant amount of memory allocation per object. But you - cannot assume the existence of object namespaces anymore. - That means: - Object o - set o::var 1 - returns TCL_ERROR: parent namespace does not exist. Use - o set var 1 - instead. Same appears for append, lappend, trace, array and - other Tcl variable handling commands. - "info exists" is problematic because it does not return an - error message: - Object o - o set i 1 - info exists o::i - returns 0. - It is save to use all Tcl command together with instvar. - - new method "requireNamespace" on Object. Creates an object - namespace explicitly. - - new info option "hasNamespace" on Object: returns 1, if the obj - currently has a namespace, otherwise: 0. - - eliminated "returnCode" on RUNTIME_STATE due to several bugs, - why was it there??? + - fix typo -2001-09-14 Uwe Zdun - * xotcl.c: - - Changed XOTclCInfoMethod to be based on two switch statement - instead of ifs.

Also, unknowns in method ensembles have the unknown + method listed first in objv. Alternatively, we might review how + objc/objv make it into DispatchUnknownMethod() (there are just + two call sites). But this would merely shift/spread the + skipping. Changing the arg vectors, to begin with, (e.g. + removing "-local", "-system", etc. from the objv) would + requiring rebuilding the arg vector. + - tests/parameters.test: Added a simplistic test case to catch the + error reporting for XOTcl 2's residualargs handling. -2001-08-13 - * patch release of source distribution (0.85.3) - * following naming conventions of Tcl for minor changes +2011-11-01 Gustaf Neumann -2001-08-11 - * xotcl.c. predefined.xotcl: fast parameter inst-commands - * xotcl.c: new instcommand for Object: parameteradd - (to register the instcommand for parameters) - * xotcl.c: applymethods renamed to configure - * xotcl.c: small speedup for assertion checking - * xotcl.c: simplified set methods -2001-08-09 - * fixes for actiweb (agent migration was broken) - * comm/Access.xotcl: a response to an HTTP-PUTS request should - not contain a body.

Prior to that fix, the intermediate (and + inactive) CMETHOD frame wrapping configure() calls caused + [current methodpath]s to report empty string elements. Added + some test cases. + - nsf.c / ObjectDispatch(), DispatchUnknownMethod(): When testing + objects as alias parameter targets, I found cases when the + default (C-level) unknown handler was invoked upon. The result + was an unknown message which reported the delegator object as + "unknown" method! This was due to injecting the delegator + object into the argument vector at position 0, subsequently + used by the C-level unknown handler. First, I tried to make the + C-level unknown handler aware of the ensemble call context (by + funneling through the CSC and frame flags) but this turned out + to be complicated to achieve this simple task. As an + alternative, I suggest the following patch: The first argument + in unknown calls is treated as a list, and dependening on the + call context (ensemble vs. non-ensemble) contains all the + necessary call data. For ensemble methods, it is the delegator + object, the entire method path (as returned by [current + methodpath]), and the actual unknown selector. The default + C-level handler, treating the call info as list, resorts to + reporting the last element of the list which is always the + unknown selector.

+	  C-implemented commands. In these cases, methodName stands for a
+	  null pointer, so we need to fall back to Tcl_GetCommandName().
+	- nsf.tcl / ::nsf::mixin: The proc implementation used "mixin" rather
+	  than "class-mixin" as (default) relation type.

+
+
+	- Experimental Object-System specific resolver in method bodies
+	  (allows resolving to the "right" next, self, etc. without
+	  namespace imports/paths)
+	- deactivated automatic namespace path copying for child-objects
+	- extended regression test
+
+
+	- frame skipping in cmdresolver apprantly not needed anymore
+

+
+	- removed method "setter" from migration guide

+
+	- serializer: updated serializer to avoid calls to "setter"
+	- extended regression test
+
+
+	- nx::test: made differences in regression test easier to read
+
+
+	- doctools: changed "-slotclass" to "-class"
+
+
+	- removed method "setter" from nx
+	- nx method "attribute": changed name of nonposarg from
+	  "slotclass" to "class"
+	- fix bug for "C class-object attribute foo" (incorrect forwarder)
+	- extended regression test
+
+2010-12-15  ssoberni  
+
+
+	- Changed parametersyntax visualisation to show
+	  variable/replacable elements in italics.
+	- Rewrote the method template for attribute accessors/mutators
+	- Revised and refactored the resolution helper of member entities
+	  along an inheritance path to reflect member overloading
+	- Reduced verbosity
+
+
+	- Adjusted the TODOs
+	- Completed marking internally-called methods and provided a
+	  first documentation draft for them.
+	- Fixed the indentation level for code listings
+	- Now using method.html.tmpl to render per-object methods in
+	  class.html.tmpl
+	- Fixed return (out parameter) validation
+
+2010-12-15  Gustaf A. Neumann  
+
+
+	- "/obj/ info method parametersyntax /method/": return results of
+	::nsf::parametersyntax in case, the parametersyntax cannot obtained
+	from a parameter definition (e.g. the method is a forwarder to a tcl
+	cmd).
+
+2010-12-14  Gustaf Neumann  
+
+
+	- streamlined error messages
+	- removed NsfErrBadVal() and replaced it with a generalized version of
+	  NsfObjErrType(
+
+
+	- made error messages more consistent
+	- improved error messages for "returns" and "nsf::is" (omit parameter
+	  name)
+
+2010-12-14  ssoberni  
+
+
+	- Adjusted for multiplicity types
+	- Added new templates: attributemethod.html.tmpl is responsible
+	  for rendering accessor/mutators for attribute slots,
+	  object.html.tmpl for objects.
+	- I now render attribute slots both in their object parameter
+	  view & a method view. Furthermore, I distinguish between the
+	  incremental vs. ordinary interface (as requested).
+	- Fixed div boxing scheme (again)
+	- Adjusted various places (method.html.tmpl, submethod.html.tmpl)
+	  to display the status marks (more to come)
+	- Streamlined the method views, introducing Type and Protection
+	  sections
+	- Started adopting the /obj/ prefix in parameter listings
+	- Made the @use mechanism working again (under validation). Once
+	  tiny bit needs to be fixed: The upward propagation of status
+	  messages if @use is in place.
+	- Removed the cause for redundant validation calls by traversing
+	  the entity hierarchy only once.
+	- Added nx-specific tracers (to distinguish between ensemble and
+	  slot objects, ...) For now, they work fine, but are tangled
+	  with non-nx tracing. This needs refactoring.
+	- Added another nx-specific tracer which tackles the issue of the
+	  __resolve_method_path helper. While quite cumbersome and
+	  coupling nxdoc to many internal design decisions of nx, it
+	  turns any change in nx.tcl unnecessary.
+	- Fixed ::nx::doc::handleinfo to deal with objects as methods
+	  (the case for intermediate ensemble objects).
+	- Added ::nsf::setter support
+	- Fixed the validation support for submethod structures.
+	- Some cleanup (to be continued)
+
+2010-12-14  Gustaf A. Neumann  
+
+
+	- provide warning if nonpositional argument is passed more than once
+
+
+	- improve wording in comment

+2010-12-11  Gustaf A. Neumann  
+
+
+	- added returns handling for nx in serializer

+
+
+	- extended regression test
+
+
+	- further cleanup of error procs: eliminated NsfObjErrArgCnt()
+	- improve error message, when too many arguments are passed
+
+
+	- fix messages when test fails
+
+

+2010-12-11  Gustaf Neumann  
+
+
+	- added strnstr emulation for installations without having it
+
+2010-12-10  Gustaf A. Neumann  
+
+
+	- new printf-style error message generator: NsfPrintError()
+	- simplified error handling: removed NsfVarErrMsg() and NsfErrMsg() and
+	  replaced it by NsfPrintError()
+
+
+	- fixed bug with required last object parameter without provided
+	  value
+	- extended regression test
+
+
+	- apply allowempty only on list, and not to elements
+
+
+	- fix a few typos in TODO
+
+
+	- introduced a few forms of multiplicty
+	  * 0..1 allow empty value
+	  * 0..* list, can be empty (equivalent to 0..n)
+	  * 1..* list, cannot be empty (equivalent to 1..n)
+	- deprecate multivalued in parameter specs in favor of multiplicty
+	- deprecate allowempty in parameter specs in favor of multiplicty
+	- adjust regression test
+
+
+	- make "... info children ?pattern?" compliant with XOTcl 1; if
+	  pattern contains no wildcard and is no absolute path, nsf
+	  completes it. (eg. Object create o; Object create o:x; o info
+	  children x" will return ::o::x)
+	- extended regression test
+
+
+	- quote name of referenced parameter in error message to ease
+	  reading
+	- new parameter checker "parameter", performing an approximate
+	  checking for valid parameter specs
+	- set NSF_ARG_CHECK_NONPOS only when there are multiple arguments
+	- remove space checking for NSF_ARG_CHECK_NONPOS in favor of parameter
+	  checker
+
+
+	- minor cleanup
+
+
+	- provide a generic logging interface
+	  * predefined for plain Tcl and aolserver/naviserver
+	  * C-level: NsfLog()
+	  * Tcl-level: ::nsf::log
+
+2010-12-10  ssoberni  
+
+
+	- Fixed some naming confusion around @class-object-method
+	- Completed statusmark support down to the @param level
+	- method parameter definitions are now pre-processed during
+	  tracing; see ::nx::doc::paraminfo
+	- Continued the pinfo/pdata-based refactoring
+
+2010-12-09  Gustaf A. Neumann  
+
+
+	- xotcl2.tcl: fix the default init handler
+	- nsf.c: provide warnings when unchecked parameter values might
+	  conflict with nonpos args
+
+
+	- nsf.c: aquire parameter structure for returns more lazyly
+	  (otherwise, a serializer handling returns would aquire the
+	  structure for every argument)
+	- extend regression test
+
+
+	- xotcl2.tcl: cleanup of forward implementation
+	- xotcl2.tcl: provide debug version of default init method
+
+
+	- nx.tcl: cleanup of forward implementation
+
+2010-12-09  ssoberni  
+
+
+	- Fixed an issue when accessing partly initialised NsfParamDefs
+	  (created e.g. by [::nsf::methodproperty ... returns]) from
+	  [info method] subcommands, previously leading to invalid memory
+	  accesses. Added a test to tests/returns.test.
+	- Minor correction: xotcl2's method_handle_to_xotcl was not aware of
+	  the change to "class-object" as scope modifier.
+
+2010-12-08  Gustaf A. Neumann  
+
+
+	- NSDeleteChildren: delete objects before classes
+	- NSDeleteChildren: delete here aliases as well

+2010-12-07  ssoberni  
+
+
+	Accomplishments:
+	- Completed a first version of the sandboxed (partial) evaluation
+	  of Tcl source artifacts (packages, script files, C extensions)
+	  based on a dedicated child/slave interp environment: see
+	  ::nx::doc::Sandbox; the test suite and the test documentation
+	  builts run on it.
+	- Based on this infrastructure, we can now generate a snapshot of
+	  a program's structure to be documented (and contrast it to the
+	  explicitly documented structure).
+	- Added simplistic css sprites for visualising the doc entity
+	  status (extra, missing, mismatch, complete); see also
+	  library/lib/doc-assets/status.svg and
+	  library/lib/doc-assets/status.png
+	- The entity status is printed optionally along with the print
+	  name of an entity
+	- Added switch-like parts to represent properties of doc
+	  entities: @deprecated, @stashed, @c-implemented, @syshook. The
+	  implementation and use of ::nx::doc::SwitchAttribute should be
+	  reviewed after having figured out how to proceed using
+	  "switching" objparams.
+	- I provide a multi-property dispatcher as doc-syntactic sugar and for
+	  mere convenience: @property
+	Various:
+	- Corrected some div-boxing mess in the templates
+	- Added a filtered helper to process entity collections
+	- Made the mixin layer infrastructure more symmetric (a revoke
+	  operation).
+	- Added tracers for ::nsf::method and ::nsf::alias (remains to be
+	  completed)
+	- Renamed ::nx::doc to ::nx::processor and turned it into another
+	 mixin layer to trace the doc entity creation in e.g. readin()
+	- Companion (*.nxd) files: Revised the handling of companion
+	 files. Temporarily moved generic/nsf.nxd in the top-level
+	 directory. We need to find a permanent place as its location is
+	 currently derived from the location of the shared extension. A
+	 candidate is doc/ but this is not linked to the shared extension
+	 location at all.
+	- processor.readin() now returns a collection of entities created
+	 during its execution.
+	- Improved robustedness and orthogonality: destroy hooks; the
+	 tag-dispatcher can now handle empty comment lines; when placing NSF
+	 object tracer, we now use the freshly added introspection of an
+	 object system's method aliases.
+
+2010-12-06  Gustaf A. Neumann  
+
+
+	- Converted migration guide to asciidoc
+	- Overhaul of serveral sections in asciidoc
+	- Developed styles for nx for migration guide (.css and
+	  source-highlight)
+

+
+
+	- rebuild pkgIndex.tcl more eagerly

+
+
+	- added mode-hint for Emacs
+
+
+	- remove CVS tag

+
+
+	- nx.tcl: removed debugging output

+	  $b}] } }
+	- extended regression test
+
+
+	- xotcl2.tcl: added empty namespace eval to make package indexer happy
+
+2010-11-22  Gustaf A. Neumann  
+
+
+	- small cleanup
+
+2010-11-22  ssoberni  
+
+
+	 - Conditionally disabling redefine protection (based on the
+	  presence of a global var ::nsf::bootstrap) failed due to the
+	  result flag not being set to TCL_OK in this case.
+	- Adding a (redundant) [package provide nsf /version/] to the ifneeded
+	script in nsf's pkgIndex.tcl. Background: [load] is only executed
+	once (leaving aside [unload]) for a given interp. Hence, the
+	initialization function and its Tcl_PkgProvide() call are only
+	performed once. A subsequent [package forget] and [package req] barfs
+	because the package version information is removed internally upon
+	[package forget]:
+	 "attempt to provide package nsf 2.0.0 failed: no version of package
+	 nsf provided"
+	 The Tcl docu provides hints on this requirement (for C
+	 extensions); see man for [package provide]:
+	 "[package provide] is typically invoked once as part of an ifneeded
+	 script, and again by the package itself when it is finally loaded."
+	 Note that most C-extension packages (sqlite, tdom) do not meet this
+	 requirement.
+
+2010-11-22  Gustaf Neumann  
+
+
+	- provide a more explicit way to handle resourcing after a "package
+	  forget" in the info methods (similar to Stefan's suggestion).
+
+
+	- keep DEVELOPMENT macro
+
+
+	- changed relation handling by evaluating the relationcmd in the
+	  parent context to keep evaluation order.
+	- extend introspection "nsf::configure objectsystem": the command
+	  returns now all system methods in the syntax of
+	  nsf::createobjectsystem
+	- "nsf::createobjectsystem" creates now a warning when an
+	  existing objectsystem is redefined and ignores the new
+	  definition attempt. This was done with the purpose to allow
+	  "package forget nx; package require nx"
+	- Allow overwriting of redefine protected method during bootstrap
+	  to ease "package forget nx; package require nx"
+	- forward had just "-objscope", no general "-frame
+	  method|object". Since forwarder have client data, they always
+	  push a method frame. So, the situation is different to
+	  nsd::alias and ::nsf::dispatch. Therefore, the flag "-objscope"
+	  was renamed to "-objectframe" to provide better consistency
+	  with "-frame object"
+	- fixed bug, where error handling of invalid options in
+	  ForwardProcessOptions() could lead to a crash
+	- return forwardoption "-earlybinding" via instrospection
+	- extended regression test
+
+2010-11-14  Gustaf A. Neumann  
+
+
+	- perform relation handling in objectparameters outside of object-frame
+
+
+	- reduce verbosity
+
+2010-11-11  Gustaf A. Neumann  
+
+
+	- configure.in: removed --with-tclinclude option, since it appears to
+	be included in tcl.m4 (since a while). Many thanks to Victor Guerra
+	for noticing it.

+
+2010-11-10  Gustaf Neumann  
+
+
+	- disallow object parameter of type "switch" to avoid possible
+	  confusion between (a) providing a value for the o.p., (b)
+	  calling it as a setter, and (c) calling it as a getter. For
+	  providing a value, no arg is used for switch. For calling a
+	  setter, it is necessary to provide a value even for a switch.
+	- disallow type "switch" in setter definiton (use boolean instead)
+	- disallow type "switch" for positional arguments (use boolean
+	  instead)
+	- extended regression test
+
+2010-11-08  Gustaf A. Neumann  
+
+
+	- improve documentation
+
+
+	- Make sure that DispatchDestroyMethod() calls as well protected
+	  destructors
+	- New function NSCheckNamespace() as replacement for
+	  NSCheckForParent()
+	- pass parentNsPtr around instead of recomputing it in
+	  NSCheckForParent()
+	- removed unneeded argument from NSGetFreshNamespace()
+	- switched to dstring operations in NameInNamespaceObj() (seems
+	  slightly faster)
+	- factored out NSRequireParentObject()
+	- by the measures above, we obtained some speed improvements
+	- moved some more debug output to be controlled by the debuglevel
+	- extended regression test with testcases for creation of parent
+	  objects via method "__unknown"
+
+2010-11-04  Gustaf A. Neumann  
+
+
+	- provide error message, when provided setter name starts with a colon

+	Squashed commit of the following:
+	commit 370f47d26099dd8cda4125de67048461edb797a9
+	Author: ssoberni 
+	Date: Thu Nov 4 10:56:11 2010 +0100
+	 Due to recent changes in InterpColonVarResolver() to handle the
+	 slow-path execution the byte-compiled [variable], an unwanted
+	   interaction between ::nsf::setter, *certain* per-object namespaces,
+	 and the ColonCmd()-based invocation of setter methods became
+	 visible. In short: Given a pre-existing Tcl namespace and the
+	 colon-prefixed call specification to a setter method,
+	 InterpColonVarResolver() handles the var resolution request issued by
+	 the setter method (or SetInstVar(), more precisely). In a
+	 colon-prefixed call, the Tcl_Obj carrying the setter method name and
+	 used to lookup the object variable contains the ":". At the same time,
+	 the per-object namespace causes the TCL_NAMESPACE_ONLY flag to be set
+	 which causes InterpColonVarResolver() to pass on the request. In this
+	 setting, we end up with colon-prefixed object variables! See
+	 tests/parameter.test for an explanatory test case. For the time being,
+	 I fixed this by preserving and using the original, colon-free Tcl_Obj
+	 indicating the variable name in the client data structure of the
+	 settercmd.
+
+2010-11-01  Gustaf A. Neumann  
+
+
+	- show "unwind unstacked entry" message appear only when debug
+	  level>0
+	- removed fixed TODO entries
+
+
+	- fix a bug, where "o configure" (without arguments) resetted
+	  initialied values to the defaults.
+
+2010-10-31  Gustaf A. Neumann  
+
+
+	- added "nosetter" automatically, when attribute ":method" is used
+
+
+	- improving error messages from argument parser
+	- test "namespace current" and "self" in "contains" and "slots"
+	  regression test
+
+
+	- fix escaped duplicate line
+
+
+	- activated SKIP_LAMBDA in nsfCallstack. As a consequence, we disallow
+	resolving self/my ... from tcl-proc frames (use uplevel if necessary,
+	avoid "namespace eval")
+
+2010-10-30  Gustaf A. Neumann  
+
+
+	- fix wrong "self" inside contains
+
+2010-10-29  Gustaf Neumann  
+
+
+	- added new contains definition based on "apply" instead of
+	  "namespace eval". Main intention is to replace SKIP_LEVELS by
+	  SKIP_LAMBDA
+	- added functionality to use ":attribute contains:method,nosetter"
+	- added regression test for contains and attributes of type method
+
+2010-10-29  Gustaf A. Neumann  
+
+
+	- added an experimental code for setting parent namespace path as
+	default for child-objects. At the time when an object namespace is
+	created, the namespace path of the parent object is copied to the child
+	as default value.
+
+2010-10-28  Gustaf A. Neumann  
+
+
+	- gentclApi.tcl: added optimizer rule for single argument of type
+	  tclobj
+	- improved speed of CompiledLocalsLookup slightly
+
+2010-10-28  Gustaf Neumann  
+
+
+	- impoved NsColonVarResolver, made some assumptions explicit
+
+
+	- fixed scoping issue, when "-volatile" was used for object
+	  creation
+	- added regression test for interaction between filters and
+	  function resolver (and volatile)
+	- reactivated new volatile test in destroy.test
+	- undone temporary fixes for volatile in serializer and nx.tcl
+
+2010-10-28  Gustaf A. Neumann  
+
+
+	- temporary fix in serializer
+
+
+	- fixed langauge hooks for emacs
+
+
+	- updated TODO
+
+
+	- added deavtivated test for volatile via flag (unsetteled issue)
+
+
+	- output object frame to ease interpretation of [info frame]
+
+
+	- new function MethodNameString() to obtain name without colon
+	  prefix from tcl_obj
+	- fix bad interaction between filters and cmd name resolvers
+	- output object frame to ease interpretation of [info frame]
+
+2010-10-28  ssoberni  
+
+
+	Adding the -force flag to [namespace import ::xotcl::*] to guard
+	against "can't import command ... already existings" error exception
+	(observed under OpenACS package upgrading)
+
+2010-10-27  Gustaf A. Neumann  
+
+
+	- changed CallStackGetActiveProcFrame() to return also CMETHD
+	  frames This allows to execute :volatile in a initcmd and to
+	  delete the object at its end. As a consequence, code like
+	  [CopyHandler new -volatile] copy [::nsf::self] $newName has to
+	  be changed to CopyHandler new { :copy [:uplevel ::nsf::self]
+	  [uplevel set newName] :destroy }
+	- renamed CallStackUseActiveFrames() to CallStackUseActiveFrame() and
+	  ctx->framesSaved to ctx->frameSaved to reflect implementation
+
+2010-10-26  Gustaf A. Neumann  
+
+
+	- removed debugging from CscFinish when compiled without DEVELOPMENT
+
+
+	- remved debugging from NsfCleanupObject when compiled without
+	  DEVELOPMENT
+
+
+	- added regression tests for destroy-during-init
+
+
+	- renamed nx regression tests .test to follow tcl conventions
+
+
+	- extended regression tests for aliases to procs
+
+
+	- allowed public|protected for method deletion such as "Object
+	  public method foo {} {}"
+	- removed defaultMethodCallProtection in alias test
+
+
+	- fixed bug when calling aliased proc not via method interface
+	- fixed bug when calling destroy in initcmd
+
+2010-10-25  Gustaf A. Neumann  
+
+
+	- added a few more small optimization.
+	- code-generator: don't call argument parser, when no arguments are
+	  specified
+
+2010-10-24  ssoberni  
+
+
+	 - Adding some tests on the interactions between our var
+	  resolvers and link-creating commands: [variable], [upvar],
+	  [global], ...
+	- Amended the in-code documentation for InterpColonVarResolver(),
+	  InterpCompiledColonVarResolver() and CompiledColonVarFetch().
+	- Found another AVOID_RESOLVERS victim: [namespace which -variable
+	  /varName/]
+
+2010-10-23  Gustaf A. Neumann  
+
+
+	- removed bug-alert from nx.tcl (wrong false-positives for
+	  compiled locals in slots)
+	- added a few small optimization. nsf appears to run on the shootout
+	benchmark the same speed like a year ago (which much less
+	functionality)
+
+
+	- removed bug-alert from nx.tcl (wrong false-positives for compiled
+	  locals in slots)
+
+2010-10-22  Gustaf A. Neumann  
+
+
+	- implemented exported command ::nsf::self as fast conveniance
+	  replacement for "::nsf::current object".
+
+2010-10-21  Gustaf Neumann  
+
+
+	- make exit more silent, when not debugging
+
+2010-10-21  Gustaf A. Neumann  
+
+
+	- don't relay on gcc extensions
+
+
+	- make sure, standard pre-processors can process this file
+
+2010-10-20  ssoberni  
+
+
+	- Providing a fix (and some analysis documentation) for the
+	  prefixed-(":")-variable resolution, making the entire mechanism
+	  more robust under situations of var resolvers for compiled and
+	  non-compiled script execution interacting.
+	- Added a first sample test (which documents the motivating issue
+	  observed for AOLserver vs. NaviServer)
+	- Further testing and documenting are pending
+
+2010-10-18  ssoberni  
+
+
+	- Added a missing squared brace in the serializer
+	- Made sure that alias definitions are properly serialized: Starting at
+	a cutoff of 2 did not reflect the change of access modifiers being
+	reported in the alias definition string. Therefore, the cutoff
+	referred to the alias method itself, leading to an erroneous
+	::nsf::alias statement being generated.
+
+2010-10-16  Gustaf A. Neumann  
+
+
+	- make sure not to return CompiledLocal vars from
+	  InterpColonVarResolver() when TCL_NAMESPACE_ONLY is requested.
+	- delegate always from InterpColonVarResolver() to other resolvers,
+	  when TCL_NAMESPACE_ONLY is requested.
+
+2010-10-15  Gustaf A. Neumann  
+
+
+	- provided parametersyntax definitions for XOTcl 2.0 similar to nx for
+	  all methods without a spec (e.g. fur builtin Tcl cmds, forwarders)
+
+
+	- follow current Tcl vonvention for patchlevel var:
+	- changed name of ::nsf::patchlevel to ::nsf::patchLevel
+	- changed content ::nsf::patchLevel from eg .0 to full number including
+	  release details
+	- fixed bug in ::variable with colon-prefixed name
+	 (shadowCommands does not help, see above)
+	- removed traces of Nsf_VariableObjCmd()
+	- extended regression test
+
+2010-10-15  ssoberni  
+
+
+	- Corrected the link generation for autocomplete/search entries
+	  in case of @use chaining and made them location-independent
+	- Removed an superfluous div-closing tag in class.html.tmpl
+	- Refactored the backend code for the auto-completion search box,
+	  separating the concerns of rendering the JS array of hashes and
+	  serialising entities into a dict representation. The latter
+	  allows to discriminate entity-specific rendering behaviour
+	  (together with the mixin layer facility).
+	- Added the entity type (its pretty name) to the search results
+	  presented to the doc user.
+	- Removed the unwanted "::"s from @project and @package names.
+
+2010-10-14  ssoberni  
+
+
+	 - Switch to print_name() for rendering entity names for the
+	  search box
+	- Fixed the @parameter generation in method.html.tmpl
+	- @glossary: Support for referencing glossary entries with
+	  certain formatting annotations: @gls (minor letters only), @Gls
+	  (title), @glspl (plural), @Glspl (title plural), ... Added
+	  explicit acronym rendering (long and short forms): @acrfirst,
+	  @acr; fixing an id-generation issue for @glossary entities
+	- Completed the first round of amending nx.nxd with @glossary
+	  entries and references.
+	- I got rid of curly braces ("{", "}") as marker symbols
+	  ("{{...}}", "{{{ ... }}}") for formatting fragments of comment
+	  blocks. They proofed sufficiently hairy due to their heavily
+	  loaded meaning for the Tcl parser (the unclosed brace issue in
+	  Tcl comment blocks, the list-like processing in our comment
+	  block parser, ...). Instead, I introduced <<...>> for link-like
+	  elements (anchors, glossary references) and MediaWiki-like
+	  '''...''' blockmarkers for code listings. Thanks to Victor
+	  Guerra for reviewing and discussing this concrete-syntactic
+	  design decision.
+	- Increased the robustness of line-by-line parsing for comment
+	  blocks. Within the comment block parser, we operate on comment
+	  lines as Tcl lists (lindex, lassign, ...). While convenient
+	  from a processing perspective, this risks limiting the degrees
+	  of freedom when writing comments (e.g., using tabs and spaces
+	  to indent inline, grouping words to form lists of lists, ...).
+	  By leveraging "args" argument processing through [apply] for
+	  line preprocessing, we balance the two requirements.
+	- Verified that @use works between objects and methods.
+	- Some cleanup in the mixin layer code
+	- Resolve interp-alias chains to entity class objects explicitly
+	- Adjusting the Container/Containable mechanism to apply only to
+	  part classes relevant to particular container entities.
+	- Fixing support for package rendering as top-level entities
+	  (e.g., in the leftbar menu)
+	- Providing the project object to all entities subject to
+	  template processing.
+	- Declaring some forwarders public explicitly (to reflect recent
+	  changes in the reach of default call protection)
+
+2010-10-12  Gustaf A. Neumann  
+
+
+	- made handling of unstacked entries optional by defining macro
+	  CHECK_ACTIVATION_COUNTS)
+	- added macro NSF_DEVELOPMENT for toplevel handling if NDEBUG and
+	  CHECK_ACTIVATION_COUNTS
+	- cleanup of method-modifiers.tcl
+	- updated next migration guide
+
+2010-10-11  Gustaf A. Neumann  
+
+
+	- added handling of unstacked csc entries (removed all DEBUG warnings).
+
+2010-10-10  Gustaf A. Neumann  
+
+
+	- copied decls for objectMethod and classMethod as comments to
+	  nsf.c, fixed order
+	- documented a few functions
+
+
+	- use "nsf::configure debug" for value 1: compain about protected
+	  value >1: provide load messages for nx and xotcl
+	- unset unneeded variables in ::nx namespace
+
+
+	- fix requiredness of several info methods
+	- added "nsf::configure debug ?level?"
+
+2010-10-09  Gustaf A. Neumann  
+
+
+	- renamed some arguments of tcl interface to increase consistency
+	- make requiredness explicit for nsf::cmds
+	- introduce ::nsf::parametersyntax to provide syntax for
+	  potentially missing definitions
+	- provided ::nsf::parametersyntax for 3 ::nsf commands and 7 nx methods
+	  (from relationslots)
+
+2010-10-08  Gustaf A. Neumann  
+
+
+	- replaced "-objscope" and "-nonleaf" by "-frame
+	  object|method|default" for nsf::alias and nsf::default
+	- added functionality for "-frame method" to nsf::dispatch
+	- made the order of argument in ::nsf::alias and method "alias"
+	  the same (always first the method, then "-frame ...")
+	- extened regression test
+
+2010-10-07  Gustaf A. Neumann  
+
+
+	- added support for aolserver (essentially Makefile +
+	  aol-xotcl.tcl)
+	- removed unneded content from serializer output
+
+
+	- regenerated content
+
+
+	- added expermimental code to avoid "variable :x" crash based on
+	shadowCommands, but this does not work, when varible is bytecompiled.
+	deactivated for now.
+
+
+	- added functionality to show enumerated values in "info
+	  parametersyntax"
+
+
+	- removed CheckAllInstances()
+
+
+	- fixed aliasing warning for gcc 4.4.4
+
+
+	- fixed one aliasing warning for gcc 4.4.4
+
+2010-10-06  Gustaf Neumann  
+
+
+	- iteration over TODO file
+	- removed obsolete entries from generic/nsf.decls und
+	  generic/nsfInt.decls
+	- removed NSF_CMD_NOT_FOUND
+
+2010-10-06  Gustaf A. Neumann  
+
+
+	- updated TODO
+
+
+	- cleanup aol-xotcl.tcl and document usage in aolserver and naviserver
+
+
+	- make pickier compiler happy
+
+
+	- keep track of defaultMethodCallProtection and
+	  defaultAttributeCallProtection in serailizer
+
+
+	- document usage
+
+
+	- align logic with nstrace for naviserver
+
+
+	- remove obsolete TK_LIB_SPEC
+
+
+	- Implemented built-in-converter for "baseclass" and "metaclass".
+	  Change in performance for this call. >8 times faster before:
+	  parameters/parametercheck.007: 19.49 mms, ::nsf::is baseclass C
+	  after: parameters/parametercheck.007: 2.32 mms, ::nsf::is
+	  baseclass C
+	- remove scripted definition of "baseclass" and "metaclass"
+
+
+	- call scripted converters without checking protection
+	- removed defaultMethodCallProtection from tests/parameters.tcl
+
+2010-10-05  Gustaf A. Neumann  
+
+
+	- fixed wording
+
+
+	- changed option -expand in "info methods" and "info lookup
+	  methods" into "-path" to associate with the method path
+	- changed method property name from "protected" to
+	  "call-protected"
+	- changed nx::defaultMethodProtection to
+	  nx::defaultMethodCallProtection
+	- nx::defaultAttributeProtection is used for scripted methods,
+	  forwarders and aliases
+	- added nx::defaultAttributeProtection, used for setter and attributes
+
+
+	- changed option -expand in "info methods" and "info lookup methods"
+	  into "-path" to associate with the method path
+
+
+	- cleanup of __resolve_method_path
+	- change TclShowStack into NsfShowStack() to avoid possible
+	    interference with the Tcl* namespace
+	- made the following function static to avoid pollution of the global
+	  link namespace: CompiledColonVarFree(), GetRegObject(), ParamGetType()
+
+
+	- Methodpaths can be used now in the definition of "method",
+	  "alias" and "forward." We do not support it for "setter" and
+	  "attribute", since these require a parameter spec, which does
+	  not have clear semantics for a method path.
+	- scripted definition of nx::Object.forward and nx::Class.forward
+
+2010-10-05  ssoberni  
+
+
+	 - Major refactoring based on a minimal Mixin Layer facility to
+	  modularise optional features (such as templating, documentation
+	  verification etc.) in layers of mixins to be applied to the
+	  entire entity hierarchy.
+	- Rewrote the html templating machinery in terms of a mixin
+	  layer: NxDocRenderer
+	- Used the new modularisation granularity to add
+	  @glossary-specific link rendering (following ideas from
+	  http://www.alistapart.com/articles/hattrick/)
+	- Completed glossary support and added acronym handling
+	- Added back references and ref counting for @glossary entries
+	  (to be displayed with the glossary lists)
+	- I added the short-cut lists for selected part types of @class
+	  entities, namely @class-method and @class-attribute.
+	- Fixed the rendering of methods and attributes for ascending
+	  alphabetical order.
+
+2010-10-05  Gustaf A. Neumann  
+
+
+	- added syntax "?arg ...?" in parametsyntax output for "args"
+	- removed "info forward" from nx::Object and nx::Class (can be replaced
+	  by "info methods" and "info method")
+
+
+	- allow %method in forwarder.
+	- defined unknown methods as call-protected
+	- make __default_method_protection protected
+
+
+	- extended regression test for "current methodpath"
+
+
+	- push stack frame before calling the defaultcmd of an ensemble
+	  object to make implementation more simple.
+	- simplified EnsembleObject.defaultcmd and EnsembleObject.unknown
+	  significantly, scripted support methods are removed.
+	- extended regression test
+
+
+	- nsf::current: new option "methodpath", returns the full name of
+	  an ensemble method starting from the ensemble root.
+	- documented functions in nfsStack.c
+	- removed obsolete CallStackGetFrame(), replaced by
+	  CallStackGetTopFrame()
+
+
+	- factored out ParamGetType() to obtain from a paramPtr a type
+	  string
+	- parametersyntax:
+	  * changed "... -x arg ..." into ".... -x value ..."
+	  * changed multiple values notation from "list" to "..."
+
+
+	- strip space from source files
+
+2010-10-04  Gustaf A. Neumann  
+
+
+	- "info method parametersyntax" returns now for all nonpos args
+	  the type instead of "arg" when possible (eg ..... ?-x object?
+	  ....)
+	- extended regression test
+
+
+	- provide full set of ensemble methods from EnsembleObject.unknown
+	(i.e. from all classes along the precedence order. It was necessary
+	to pass calling object as first argument)
+
+
+	- "info lookup methods": order of non-pos parameters
+	  alphabetically
+	- added option "-expand" to "info lookup methods ". It collects
+	  ensemble methods along the precedence path
+	- added support for ensemble methods in "info lookup method"
+	- extended regression test
+
+2010-10-03  Gustaf A. Neumann  
+
+
+	- updated TODO
+
+
+	- make serializer more quiet
+
+
+	- nsf.c: use name "varTablePtr" instead of "varTable" when
+	  referring to the table
+	- new option "slotcontainer" for "methodproperty" to flag
+	  slotcontainer to make them easier to process in the serializer
+	  . don't report slot container in "info methods -expand"
+	- new function "::nx::isSlotContainer" to centralize checking for
+	  slotcontainers (used by serilaizer)
+	- support export of method ensembles in serializer
+
+2010-10-02  Gustaf A. Neumann  
+
+
+	- new option "-expand" for "obj|class info methods" to return
+	  compound names (i.e. it lists the full ensemble names) Example:
+	  ::nx::Object info methods -expand "*filter*" returns filter
+	  {info filter guard} {info filter methods} {info lookup filter}
+	- allow ensemble names in nsf::methodproperty
+	- fix compound name lookups when aliases link to shared ensemble
+	  objects
+	- make objectName() NULL-safe
+	- fix option "-source application" when applied directly on
+	  base-classes
+	- extend regression test
+
+
+	- make test more quiet
+
+2010-10-01  Gustaf A. Neumann  
+
+
+	- serializer: experimental code to serialize submethods
+
+
+	- "info method submethods": return all submethods, independent from
+	  protection
+
+
+	- fix potential crash in ::nx::Object info method definition
+	  ::nsf::methods::object::instvar
+
+
+	- fix typo
+
+
+	- slots:
+	  * change name "initcmd" of "experimental slot features" to
+	  "defaultcmd" to avoid naming conflict the the initcmd executed
+	  at the initilization of a slot object (effects XOTcl as well)
+	  * make defaultcmd/valuecmd/valuechangedcmd working for nx
+	  (absence of trace method)
+	  * provide error message, when default/defaultcmd/valuecmd are
+	  used non-exclusively
+	  * make sure to init per-object slots after copy operations
+	  * make nx::Attribute.destroy more definsive
+	  * extend test cases
+
+
+	- nsf: added flag NSF_DESTROY_CALLED_SUCCESS in addition to
+	NSF_DESTROY_CALLED to distinguish between attempted and successful
+	destroy method invocations (important for cleanup)
+
+
+	- update with decls generated from tcl 8.5.9
+
+2010-09-30  Gustaf A. Neumann  
+
+
+	- serializer:
+	  * added support for ordering on aliases referencing other
+	  objects/classes
+	  * provide shared version of the method warn via alias and removed
+	  direct output to stderr
+
+
+	- XOTcl 2: allow info slots for objects as well
+
+
+	- reduce size of output of serializer
+	- make nx::Object.serialize public
+
+
+	- filter more unneeded files from tar archive
+
+
+	- extended the apply regression test
+
+2010-09-29  ssoberni  
+
+
+	 - Minor revision of template files (to unify the naming of
+	  markup labels)
+	- Removed occurrences of old [:let]
+	- Use href() helper method to generate fragments of per-document
+	  ("local") anchor names
+	- Introduced more pretty_name and pretty_plurals for part
+	  attributes
+	- Make filename generation aware of the property of being a part
+	  or partof entity!
+	- Revised the documentation of [::nsf::current] slightly
+	- Adding setter ([:!let]) and getter ([:!get]) to the templating
+	  language, both being aware of @use chains.
+	- Refactored the resolution behaviour for part levels, relative
+	  to a given entity, into a helper
+	  StructuredEntity->owned_parts(). Based on this helper, the
+	  navigation structures can be rendered on common grounds (e.g.,
+	  drop-down search box, menus in th eleft bar)
+	- Adding the attributes "pretty_name" and "pretty_plural" to part
+	  attribute slots (used for rendering section names in the nav
+	  menu etc.).
+	- Adding a helper method href() to render the href attribute
+	  values of entity anchors (links, menu items, ...)
+	- Unified the rendering of the selection data used by the
+	  drop-down box for the various entity_types, again, using the
+	  owned_parts() helper
+	- Refactored the generation of navigation menu in the left bar
+	  into a proper template: leftbar.html.tmpl
+	- Reflect recent naming changes (e.g., predefined.tcl -> nsf.tcl)
+	- Adding support for documentation inheritance; first, fixed
+	  @command support for it
+	- Refactored the upward resolution of partof entities into a
+	  central and shared facility (Entity->get_upward_path())
+	- Adjusting for changes in introspection interface
+	  (info.callable() -> info.lookup())
+	- Adding a first aliasing (@use) mechanism. Remains to be tested
+	  properly, though it works sufficiently for the known use cases.
+	- Adding some safety checks to Tag->find()
+	- Refactoring context->parse@tag to use the Tag->find() helper
+	  (now shared between tag creation and link resolution)
+	- Tag path normalisation (expanding shortcuts, balanced list
+	  check, ...) went into Tag->normalise().
+	- Changed the [:link ...] mechansism ({{@someTag ...}}) to
+	  operate on the new tag notation. Added support for sub-method
+	  and sub-command link rendering (looks sufficient for the
+	  moment).
+	- Changed the existing *.nxd companions to match these notational
+	  modifications.
+
+2010-09-29  Gustaf A. Neumann  
+
+
+	- handle call-protection in serializer (works again with OpenACS /
+	  naviserver)
+
+
+	- added public|protected to output of "info method definition" (needed
+	  to make serializer more sane, neccessary on the longer range)
+
+2010-09-28  Gustaf A. Neumann  
+
+
+	- declare publically used methods as public
+
+
+	- change namespace to nsf
+
+
+	- make return statments explicit
+
+
+	- switch back to SKIP_LEVELS for work on OpenACS
+
+
+	- updte comments
+
+
+	- fix for the bug reported by Neil Hampton
+	- added regression test
+
+
+	- fix for the bug reported by Neil Hampton
+	- added regression test
+
+
+	- used Tcl_ObjCmdProc in prototypes
+	- allow CMETHOD to be target of calling-object/calling-level
+	- added NSF_CSC_CALL_IS_TRANSPARENT to handle proc aliases
+	  transparently
+	- access self in NsfProcAliasMethod() from tcl->object
+
+2010-09-27  Gustaf A. Neumann  
+
+
+	- updated TODO
+
+
+	- removed NXSH and XOWISH from Makefile.in
+
+
+	- altered xotcl.m4 to nsf.m4 in .,
+	  library/xotcl/library/store/XOTclGdbm/,
+	  library/xotcl/library/store/XOTclSdbm/,
+	  library/xotcl/library/xml/TclExpat-1.1/
+	- removed traces of xotcl.m4
+	- removed build flags with-nxsh, with-xowish (since these are
+	  scripted now)
+	- removed flag --with-tk (not needed anymore)
+
+2010-09-27  ssoberni  
+
+
+	Removed the nxsh (@NXSH@) and xowish (@xowish@) deps of the binaries
+	target in Makefile.in (as shell deployment is now handled in the
+	install-shells target). If not removed, make would barf ...
+
+2010-09-27  Gustaf A. Neumann  
+
+
+	- added nxwish.in (scripted replacement for former xowish)
+	- added xotclsh.in (scripted replacement for former xotclsh)
+	- added xowish.in (scripted replacement for former xowish)

+	  names: parametersFromSlots ==> parametersFromSlots
+	  unsetUnknownArgs ==> __unset_unknown_args infoError removed
+	- renamed predefined.tcl into nsf.tcl
+	- remaining cmds in nsf (except __*) containing "_":
+	  ::nsf::provide_method, ::nsf::require_method
+
+2010-09-26  Gustaf A. Neumann  
+
+
+	- fixed typo in exithandler definition
+
+
+	- removed capitalization from exit handler interface
+	- reduced interface of exithandler to ::nsf::exithandler set|get|unset
+	  ?arg?
+
+
+	- renamed ::nsf::cmd::ObjectInfo into ::nsf::methods::object::info
+	- renamed ::nsf::cmd::ClassInfo into ::nsf::methods::class::info
+
+
+	- added scripted replacement for binary nxsh
+	- new define SKIP_LAMBDA to make apply tests working without SKIP_LEVELS
+
+2010-09-25  Gustaf A. Neumann  
+
+
+	- provide debugging output when varFramePtr in GetSelfObj() is
+	  NULL
+	- filter misleading "proc" entry for "info frame" for nsf-stack
+	  entries
+	- add "method" for "info frame" for nsf-stack entries
+	- defnied SKIP_LEVELS to omit optionally skipping of tcl-stack entries
+	  in GetSelfObj()

+
+	- added fake calue for cmdPtr in fakeProc to make "info frame" happy
+
+2010-09-24  Gustaf Neumann  
+
+
+	- changed "info method lookup -application" into "info method
+	  lookup -source application"
+	- introduced "info method lookup -source
+	  application|baseclasses|all"
+	- updated migration guide
+	- extended regression test
+
+2010-09-24  Gustaf A. Neumann  
+
+
+	- removed TCL85STACK_TRACE
+	- renamed cscPtr->callType to cscPtr->flags, since this is now
+	  more appropriate
+	- some more minor cleanup
+
+
+	- changed debug command __db_yield (unporable between various 8.6b*
+	  version) into __db_show_stack
+
+
+	- changed internal method name requireNamespace to "require_namespace"
+
+
+	- added tcl-cool as an additional sample-object-system for nsf
+
+
+	- minimal cleanup
+
+
+	- make "createobjectsystem" more robust (allow to provided not fully
+	  qualified names).
+
+2010-09-23  Gustaf A. Neumann  
+
+
+	- simplification and unification of unknown handling and method
+	  finalization
+	- some cleanup
+
+
+	- save snapshot; refactoring in order to ease NRE development
+	  with unified method and dipatch exit.
+	- named debugging cmds __db_*
+	- new cmd __db_run_assertions to perform checking of the internal state
+
+
+	- some refactoring for making code structure more sane for NRE (but not
+	  done yet)
+
+2010-09-22  Gustaf A. Neumann  
+
+
+	- removed third level from libary/pkgIndex.tcl (not needed)
+
+
+	- make coloncmd are NRE-enabled
+	- make every internal method invokation (NsfCallMethodWithArgs()
+	  and CallMethod()) NRE-configurable
+	- use "Nsf" prefix for global vars to avoid potential conflicts
+	- minimal support for sane-NRE patch
+	- failed so far to make my NRE-enabled
+	- new compile-flag for tracing: NRE_CALLBACK_TRACE
+	- extended regression test (added test for 8.6 apply)
+	- renamed tests/coroutines.tcl to tests/tcl86.tcl
+
+
+	- provide comments for NextInvokeFinalize()
+
+
+	- make ::nsf::next and ::xotcl::next NRE-enabled
+
+
+	- some cleanup concerning TCL_STACK_ALLOC_TRACE
+
+
+	- passing part of dispatch flags in cscPtr->callType
+	- runs now full regression test NRE enabled, but still much debugging
+	  and options for less conservative behaviour
+
+2010-09-21  Gustaf A. Neumann  
+
+
+	- make comparison slightly simpler (C style)
+
+
+	- Big internal changes for handling nre-enabled procs in more
+	situations. Handles now all nx regression tests, but fails in
+	testx.xotcl (just nre-enabled)
+
+2010-09-21  ssoberni  
+
+
+	Fixed the bitwise flag comparison in ProtectionMatches() which failed
+	to yield a boolean result. This resulted in unanticipated [obj info
+	methods -callprotection] behaviour, with the -callprotection filter
+	seemingly being ignored. Added some tests to tests/info-method.tcl.
+
+2010-09-20  ssoberni  
+
+
+	Make library/pkgIndex.tcl traversing three directory levels (instead of
+	just 2). This is necessary to catch the packages and
+	library/xotcl/library. As a symptom, xocomm.test failed. This was
+	because it was picking up comm packages in the install, rather than the
+	source tree which did not reflect the changes in the nested object
+	dispatches: [my connection foo] -> [[self]::connection foo]
+
+2010-09-18  Gustaf A. Neumann  
+
+
+	- fixed handling of TclNRRunCallbacks, such that coroutines can
+	  be easily used (more testing required)
+	- added temporary routine ::nsf::yieldcheck for coro debugging
+	- renamed Tcl85showStack() to TclShowStack()
+
+
+	- regenerated pkgindex files
+
+
+	- improved library/lib/make.tcl once more
+
+
+	- fixed again library/xotcl/library/pkgIndex.tcl
+
+
+	- regenerated index files
+
+
+	- removed unneeded line
+
+2010-09-17  Gustaf A. Neumann  
+
+
+	- added explicitly library/xotcl/library/pkgIndex.tcl
+
+
+	- make changes for public methods
+
+
+	- fixed a crash for tcl 8.6b1 in return value checking. now it
+	complains about missing cmdPtr; it is not clear, why this is missing
+	at the first place in 8.6b1 while working in 8.5
+
+
+	- merged Stefan's updates into TODO
+
+
+	- made methods (for now just scripted methods) by default
+	  protected.
+	- provide methode __default_method_protection to obtain the
+	  default method protection when neither protected or public is
+	  used.
+	- per default methods are now protected

+
+
+	- fix typo
+
+
+	- removed obsolete code
+
+
+	- handle next in ensemble with arguments
+	- extended regression test
+
+
+	- new nsf::next cmd. receives 0 or 1 argument, which might be a
+	  list of arguments. This avoids ambiguity of ::xotcl::next with
+	  "--noArgs".
+	- renamed namespace_copycmds and namespace_copyvars to nscopycmds
+	  and nscopyvars (we don't use "_" in nsf::*-names as delimiters
+	  elsewhere)
+	- renamed __qualify to qualify (it is a non-exported cmd)
+
+
+	- call internal NextSearchAndInvoke (without NextGetArguments)
+	  from the implicit next in ensemble methods
+	- made NsfNextMethod() obsolete to ease different noarg handling
+	  policies

+	fully-qualified names ::nsf::dispatch $obj
+	::nsf::cmd::ObjectInfo2::hastype $class ::nsf::parametercheck
+	object,type=$class $obj extended regression test (paramters.tcl)
+
+
+	- removed overhead on ::nsf::dispatch when called with absolute
+	  paths
+	- absolute paths have to start with ":".
+
+
+	- improve comments in nsf.c
+	- follow closer naming of Tcl style guide
+
+
+	- added "info method subcommands ..." to return list of
+	  subcommands (of the ensemble)

+	  method ..."
+
+2010-09-11  Gustaf A. Neumann  
+
+
+	- fixed handles with subcommands for class methods when called on
+	  classes or objects
+	- extended regression test
+
+

+	  NsfObjInfoMethodsMethod
+	- first part of ensemble name resolver. We can resolve now e.g.

+
+
+	- changed "info available" into "info lookup" (and accordingly c
+	  definitions, migration guide)
+
+
+	- new function AliasDeleteObjectReference() to delete aliases to
+	  objects
+	- removed some obsolete functions
+
+2010-09-09  Gustaf A. Neumann  
+
+
+	- handle aliases to (sub)ensemble objects during final cleanup to
+	  improve sharing of logic.
+	- share definition of "info callable" and "info has" ensemble between
+	  object info and class info
+
+
+	- splitted "info callable" into an ensemble (submethods have
+	  quite different signatures)
+	- added "info callable slots" with functionality of "info
+	  slotobjects"
+	- removed "info slotobjects"
+
+
+	- [::nx::Object info method parameter info] returns now empty
+	  instead of error.
+	- extended regression test
+
+
+	- added flag "-type" to NsfObjInfoChildrenMethod
+	- added flag "-type" to NsfObjInfoSlotObjectsMethod
+	- removed dummy argument "pattern" from
+	  NsfObjInfoSlotObjectsMethod
+	- removed NsfClassInfoSlotsMethod (implemented via "children ...
+	  -type ...")
+	- moved "info slots" from nx::Class to nx::Object (to report e.g.
+	  per-object attributes)
+	- extended regression test
+
+2010-09-08  ssoberni  
+
+
+	 - Added support for companion documentation files (based on the
+	  file extension *.nxd)
+	- Moved the nsf and nx documentation blocks in
+	  generic/predefined.nxd and library/nx/nx.nxd, respectively
+	- Un-exported @param, provide two aliases @attribute and
+	  @parameter (in the respective contexts).
+	- Changed the test suite and the two documentations to reflect the
+	  naming changes.
+
+2010-09-08  Gustaf A. Neumann  
+
+
+	- BRO continues:
+	- overworked function prototype definitions in nsf.c
+	- renamed some static definitions on the way to follow Tcl conventions
+	  (start with a capital character)
+
+2010-09-08  ssoberni  
+
+
+	 - Added two new templates: method.html.tmpl and
+	  submethod.html.tmpl
+	- Generalised the support for sub-commands and sub-methods,
+	  including a shortcut notation for tag lines.
+	- Adding the special handling of initcmd blocks of attribute
+	  slots: They are processed as @param specifications of their
+	  owning (class) object. In a next step, I will limit this
+	  special handling to the first comment block only, while
+	  subsequent ones are evaluated in the context of the slot object
+	  itself.
+	- Fixed an issue with cleaning up the processing-related mixin
+	  classes in the CommentBlockParser: As the nested notation of
+	  doc entities can conflict with relation slot forwarders
+	  (*::info::mixin vs. *::info mixin ), I revert to
+	  using ::nsf::relation directly.
+	- Fixed the default namespace resolution (still needs some
+	  review, once all use cases are figured out!) Changed nx and nsf
+	  documentation accordingly.
+	- Add first doc text for Object->info() and its sub-methods (for
+	  testing purposes, merely)
+	- Added an initial implementation for parsing level support. By
+	  introducing skipping axes into the tag notation (e.g.,
+	  @..param), we can now differentiate between different scopes of
+	  applications for tags. This has a number of advantages: a)
+	  processing becomes more efficient (skip-level annotated tags
+	  can be identified early), b) we do not have maintain different
+	  tag labels for different parsing levels (e.g., @child-object
+	  vs. @object), ...
+	- Parsing levels have to be maintained within the documentation
+	  processor and provided to the comment block parsers at work.
+	  This still has to be accomplished.
+	- Adapted the naming scheme for qualifier tags (for now). Instead
+	  of "child" scopes, we coerce the entity names using namespace
+	  delimiters (this fits nested objects nicely)
+	- Changed the resolution behaviour for dotted tag labels:
+	  Intermediate nodes (i.e., entities) are not allocated anymore,
+	  on the fly. Rather, it is a pure id resolution, except from the
+	  leaf element which is effectively initialised as a
+	  documentation entity. This has major implications: It requires
+	  partof entities to exist prior to any part entity. However, the
+	  id resolution work can later be reused when introducing the new
+	  tag notations into the link block markers in the templating
+	  engine (avoiding zombie and widely undescribed doc entities).
+	- Started shifting id generation into part attributes (for the
+	  time being). Probably I will do so permanently to avoid the
+	  complexity in the various new() factories for doc entity types.
+	- Adjusted the tests accordings and added many more on the
+	  navigatable tag notation.
+	- Renamed EntityClass and PartClass into Tag and PartTag. The
+	  meta-class names so better reflect their purpose as entity
+	  factory classes, based on the tag notation scheme. Added a
+	  QualifierTag meta-class which marks tags (@class, @object,
+	  @command) which impose extra requirements when not being part
+	  of another entity (in particular, default namespace
+	  resolution). If not part of another entity, they represent
+	    *qualifying* language constructs, i.e. language constructs
+	  which help identify other elements (command -> subcommand,
+	  object -> nested object or method).
+	- Started harmonising the entity class hierarchy (not ready cooked
+	yet): Entity < StructuredEntity < ContainerEntity < @project <
+	@method < @package < PartEntity < @object (@param) < @class < @command
+	The most important change is that all entities (entity instances) can
+	become parts, however, only a single entity class (@param) is critical
+	about it.

+
+	- renamed slot attribute "noforwarder" to "nosetter"
+	- method parameter can now use option "nosetter" to allow object

+
+	- make method EnsembleObject.methodPath more independet of Ensemble

+	- updated migration guide
+
+2010-09-01  ssoberni  
+
+
+	 - Replaced the former "exception" handling mechanism by a
+	  simplified one. This speeds up e.g. the generation of the
+	  current nx.tcl documentation by 15-20%.
+	- Adjusted the tests for the modified CommentBlockParser
+	  interface.
+	- Implemented a first version of the revised tagline notation.
+	  Changed the documentation in nx.tcl and predefined.tcl

+
+2010-08-30  ssoberni  
+
+
+	- Refactoring templating code: Separated generic and
+	  backend-specific templating behaviour into distinct classes:
+	  BaseTemplateData and NxDocTemplateData. Rewrote the getter
+	  logic for the @doc strings to retrieve different
+	  representations (as_text() and as_list()).
+	- Multi-line block markers: To achieve this, I moved the handling
+	  of block markers into the template data classes.
+	- Adjusted the tests for the changes ...
+
+
+	Temporarily fixed an issue with cleaning up comment section states set
+	on an entity object. This needs to be improved and to be made more
+	robust!
+
+
+	Adding tests for multi-line param descriptions
+
+
+	- Added an experimental gathering facility for part objects,
+	  relative to a given entity object. It returns a [dict] which
+	  allows to reuse the parts gathered throughout the templates
+	  rendering process.
+	  - Moved the process=@* methods to the doc object (this increases
+	  the cohesion).
+	- Adjusted the current documentation artifacts for the changes (@object
+	  -> @class where applicable).
+
+
+	- Renamed the existing object.html.tmpl to class.html.tmpl and
+	  fix it to reflect class features. Providing an object-only
+	  template remains to be done.
+	- Added an experimental gathering facility for part objects,

+	- backported fix for xotcl 1.6.6 reported by kristoffer lawsow,
+	  which helps just partly here
+	- extended regression test
+
+
+	  * Fixed bug in filters reported by Kristoffer Lawson. When a filter
+	chain reaches its end without finding the invoked method, the unknown
+	state was not resetted correctly and affected method invocations in the
+	filter after "next".
+
+2010-08-28  Gustaf Neumann  
+
+
+	- fix syntax of last commit
+
+
+	- simplified "info is"
+
+
+	- fix requiredness of last argument in parametercheck

+	  object.
+	- return valid creation command in "info method definition ...."
+	  when method is an object.
+	- extend regression test
+
+
+	- fix requiredness of last argument of objectproperty
+
+2010-08-27  ssoberni  
+
+
+	Removed some print statements and comments
+
+
+	  - Fixed a relict of switching from ::nx::core::* to ::nsf::*.
+	  Removing the *::unsetUnknowArgs script fragment from proc
+	  bodies assumed 29 characters rather than 24 characters. This
+	  left proc bodies amputated when e.g. retrieved through [info
+	  method definition] in the presence of unknown (non-initialised)
+	  proc-local variables.
+	- Corrected the submethod definition of Object->info()->is(): It did
+	not check for the existence of the optional trailing parameter and so
+	info()->is() barfed.
+
+2010-08-26  Gustaf A. Neumann  
+
+
+	- eliminated "info classparent" and "info classchildren"
+	- added tests to xotcl/tests/testx.xotcl to assure equivalence
+

+	- changed resolve_method_path to __resolve_method_path and made it
+	  protected
+
+
+	- reanimated 5 tests in tests/destroytest.tcl
+
+
+	- reanimated 5 tests in xotcl/tests/testx.xotcl
+
+
+	- Changed handling of "child objects": now, they are shown by
+	  default.
+	- At the same time, the subobject "slot" was made protected to
+	  avoid its listing per default in "info methods"
+	- unified slot parent-object creation handling
+	- changed XOTcl info to new interface
+
+
+	- some simplifications
+
+
+	- fix capitalization
+
+2010-08-25  Gustaf Neumann  
+
+
+	- fixed "info methods" and added "-methodtype all" for setting
+	  class-only
+
+2010-08-25  Gustaf A. Neumann  
+
+
+	- changed info to new interface (partly done for nx, migration for
+	  xotcl to be done)
+
+2010-08-25  ssoberni  
+
+
+	- Started separating the documentation into four documentation
+	  projects, each with its own documentation artifact: nsf
+	  (predefined.tcl), nsl/nx (nx.tcl), xotcl (xotcl2.tcl),
+	  libraries (several?).
+	- Removed documentation blocks from gentclAPI.decls
+	- Added default namespace resolution for documentation entities.
+	  @project and @package can now specify a default namespace which
+	  is applied to all relative (not fully qualified) entity names.
+	  This avoids the redundant writing of longish qualified entity
+	  names. As a @project may contain several @packages, multiple
+	  default namespaces can be specified.
+	- Added a distinct @class entity family.
+	- @project and @package can now trace the creation of specified
+	  part entities (@class, @object, @command) to be structurally
+	  linked to them.
+	- Fixed search box support for @command views
+	- Excluded template files from output directories

+	- nx: we have now "obj info mixin guard name" instead of "obj
+	  info filter -guard name"
+	- nx: we have now "obj info mixin classes ...." instead of "obj
+	  info filter ...."
+	- updated migration guide
+
+2010-08-24  Gustaf A. Neumann  
+
+
+	- started new interface bundles, objectInfoMethod and

+	- added object info methods filterguard, filtermethods, vars to
+	  objectInfoMethod
+	- added class info methods filterguard, filtermethods to
+	  classInfoMethod
+	- built a temporary solution for dispatcher "filter", since
+	  forward mangles args
+	- nx: we have now "obj info filter guard name" instead of "obj
+	  info filter -guard name"
+	- nx: we have now "obj info filter methods ...." instead of "obj info
+	  filter ...."
+
+
+	- added option "-returns" to Class.method
+	- added subcmd to method/object method in nx
+	- delete class methods in freeAllXOTclObjectsAndClasses()

+	- change further instances of "my connection" to "[self]::connection"
+	  in xo*comm*
+
+
+	- changed requireNamespace to "require namespace" in lib/make.tcl
+
+2010-08-23  Gustaf A. Neumann  
+
+
+	- implemented experimental delegating version of "object as method"
+	  that keeps the original self.
+
+2010-08-22  Gustaf A. Neumann  
+
+
+	- updated todo list
+
+
+	- deactivated "abstract"

+	  -guard name"
+	- replaced "cls object info mixinguard name" by "cls object info
+	  mixin -guard name"
+	- removed XOTclObjInfoMixinguardMethod()
+	- removed XOTclClassInfoMixinguardMethod()
+	- extended regression test
+	- updated migration guide
+
+
+	- replaced "obj|cls filterguard name cond" by "obj|cls filter
+	  guard name cond"
+	- replaced "obj|cls info filterguard name" by "obj|cls info

+	- removed XOTclObjInfoFilterguardMethod()
+	- removed XOTclClassInfoFilterguardMethod()
+	- extended regression test
+	- updated migration guide
+
+
+	- use now class-only for all methods methods of meta-classes.
+	  Methods of meta-classes are intended to be applied on classes,

+	- respect class-only in "info callable methods|method"
+	- extended regression test
+	- provided relation name "object-filter" to slot filter.

+
+	- experimental method-property "class-only": this allows to make
+	  object save against per-object mixins of meta-classes. the flag
+	  is only used in the mixin-resolver
+	- used for the time being in nx only for Class.info, but would apply as
+	  well for methods defined on both Object and Class.
+
+2010-08-20  Gustaf Neumann  
+
+
+	- changed __invalidateobjectparameter from a method of class to
+	  framework primitiv ::nsf::invalidateobjectparameter
+
+2010-08-20  ssoberni  
+
+
+	Fixed some more [info callable] occurrences
+
+2010-08-20  Gustaf A. Neumann  
+
+
+	- removed XOTCL_METHODTYPE_OBJECT from XOTCL_METHODTYPE_BUILTIN
+	- default methodtype returns now everything, which is a true
+	  method (except objects)
+	- methodtype -all includes objects
+	- the object "slot" does not appear now in the method listing per
+	  default for classes having slots
+
+
+	- removed methods object-mixin and object-filter from the
+	  interface. (Caused some duplication of logic in the method
+	  "object") _ added option noforwarder to RelationSlots
+	- some minor cleanup
+
+2010-08-20  ssoberni  
+
+
+	- Accomplished major rewrite and cleanup of the comment block
+	  parser. The revised design allows us to express parsing states
+	  (context, description, part) as well as their substates
+	  reflecting the comment line processed (tag, text, space)
+	  directly. The design follows a METHODS-FOR-STATES strategy.
+	  Also, the parsing logic is now self-contained and is not
+	  interwoven with the class hierarchy documentation entities
+	  anymore (i.e., the former process() method of Entity and its
+	  subclasses).
+	- The modal/reactive design of the comment block parser has been
+	  streamlined: There is a CommentBlockParser class which acts as
+	  the event source. The actual parsing is achieved by the
+	  mixin-refined entity objects by reacting upon the parsing
+	  events (process, parse, next).
+	- Adjusted the tests in doc.tcl accordingly.
+	- Changed occurrences of [info callable] to reflect the latest changes.
+
+2010-08-20  Gustaf A. Neumann  
+
+
+	- made slot optimizer more robust
+
+2010-08-19  Gustaf A. Neumann  
+
+
+	- checked saftey of Class.method, Class.alias, Class.setter,
+	  Class.forward
+	- made Class.filterguard, Class.mixinguard, Class.attribute
+	  robust against per-object mixins from meta-classes
+	- fixed mixin/filter delete methods with guarded operations
+	- extended regression test
+	- all methods defined on both, Object and Class are now safe in respect
+	  to per-object mixins with meta-classes
+
+
+	- made Class.info, Class.mixin, Class.filter robust against
+	  per-object mixins from meta-classes
+	- extended regression test
+
+
+	- changed "info method filter ...." into "info callable filter
+	  ..."
+	- fixed "o info callable method" in some cases with mixins
+	- extended regression test
+	- updated migration guide
+
+
+	- renamed "info method name ..." into "info method handle ...",
+	  since it returned already the handle
+	- renamed ListMethodName() to ListMethodHandle()
+	- changed output of "info callable -which ..." from definition to
+	  method handle
+	- renamed "info callable -which ..." into "info callable method
+	  ..."
+	- updated regression test to reflect the changes
+
+2010-08-18  Gustaf A. Neumann  
+
+
+	- removed method "filtersearch" from nx.tcl
+	- added "obj info method filter methodName" to nx
+	- updated xotcl.2 to use new filtersearch imprementation
+	- updated migration guide
+
+
+	- removed method "autoname" from nx.tcl
+	- added "method require autoname"
+	- added "method require exists"
+
+
+	- nsf: provided scripted support for "require/provide methods"
+	- nx: new method ":require namespace" ":require method" "require
+	  object method"
+	- added regression test method-require
+	- removed requireNamespace from nx.tcl (still exists in xotcl)
+	- replaced "requireNamespace" by "require namespace" in nx
+	  regression tests
+	- updated migration guide
+
+
+	- upgraded to TEA 3.9
+
+
+	- fixed typo
+
+2010-08-17  Gustaf A. Neumann  
+
+
+	- implemented return value checker (for scripted and
+	  c-implemented methods)
+	- additional methodproperty returns (for registering a return
+	  value checker)
+	- support for incrementally adding stuff to paramDefs (such as
+	  slotobj or return value)
+	- new c-function ParamDefsNew()
+	- added regression test for return value checker
+
+2010-08-16  Gustaf A. Neumann  
+
+
+	- commented out XOTCL_CMD_NOT_FOUND, since it seems to be
+	  obsolete by now
+	- extended regression test to avoid CallDirectly on dealloc (the last
+	  place, where XOTCL_CMD_NOT_FOUND was used)
+
+
+	- implemented parameter option "allowempty"
+	- extended regression test
+
+
+	- make one more instproc context explicit
+
+
+	- make capitalization in comments consistent
+
+
+	- make resolving context explicit in migration guide
+
+2010-08-15  Gustaf A. Neumann  
+
+
+	- added object-parameter sections to migration guide
+
+2010-08-13  Gustaf Neumann  
+
+
+	- use testfile name as additional prefix in test reports
+
+2010-08-13  Gustaf A. Neumann  
+
+
+	- sketch next migratin guide examples
+
+
+	- continue work on migration guide
+
+
+	- replaced several occurrences of "eval" in nx.tcl and xotcl2.tcl
+
+
+	- Implemented "interp alias" support for classes. In some cases.
+	  interp-aliased classes worked already without additional code,
+	  but e.g. in "... -superclass C ..." it failed. Without this
+	  feature, one could not reuse a class with a different
+	  namespace, unless it was explicitely "namespace exported" in
+	  the source. The problem was the implementation of
+	  "::nx::Attribute", which should not be exported in nx (most
+	  people do a "namespace import ::nx::*") because there is no
+	  need to do so, but ::xotcl::Attribute should reuse it
+	- without subclassing). .... However, we still seem to have a problem,
+	when the interp-aliased Class is exported and imported to a different
+	namespace.
+	- removed definition of slots from nx, changed regression tests
+	 examples to to ::attribute instead of -slots
+
+
+	- adjusted path in documentation system for nx/nx.tcl
+
+
+	- moved all exports of nsf to predefined.tcl
+	- made imports in xotcl2 and nx explicit
+
+2010-08-12  Gustaf A. Neumann  
+
+
+	- updated to TEA 3.8
+
+
+	- some updates
+
+
+	- made the "next scripting laguage" a own, loadable tcl package
+	  (currently named nx, name is subject of change)
+	- predefined.tcl is now pretty minimal.
+
+
+	- fix further pathnames
+
+
+	- refactor make file to better separate xotcl from the rest
+
+2010-08-11  Gustaf A. Neumann  
+
+
+	- changed more self/current
+
+
+	- added interp alias "nx::self" to "nx::core::current method"
+	- changed "current proc" into "current method" in scripts and tests
+
+
+	- Introduced $xotcl_target_doc_dir for generated xotcl
+	  documentation. Generate xotcl documentation in this directory.
+	- moved more (hopefully all) xotcl doc components into library/xotcl/doc
+
+2010-08-10  Gustaf A. Neumann  
+
+
+	- updated migration guide, added section for callstack
+	  introspection
+	- updated serializer for new names
+
+
+	- xotcl.c:
+	  * new function GetObjectFromNsName() to obtail object or class
+	  from a fully qualified namespace name used in method handles
+	  (such as e.g. ::nx::core::classes::X)
+	  * new function MethodHandleObj() to return a tcl_obj containing
+	  the methodhandle
+	  * removed obsolete method getFullProcQualifier()
+	  * info methods obtain now object and/or class from fully
+	  qualified method names (method handles) if possible
+	  * return message handles in "current next", "current filterreg"
+	  and "... info filter ... -order", which can be used in "info
+	  method .... " for obtaining more details.
+	  * change all occurrances of "self" in next regression tests to
+	  current.
+	- xotcl2.tcl
+	  * implemented "self" as a proc to provide extensibility and full
+	  backward compatibilty; this opens opportunity to replace now
+	  e.g. "self proc" by "current method", etc.
+	  * provide full compatibility for "self next", "self filterreg"
+	  and "... info filter ... -order", returning old-style multiword
+	  method handles (such as e.g. "::C instproc foo")
+	- changed "next" to current in documentation framework and templates
+
+
+	- iterated through doc.tcl-TODOs
+	- changed CheckVarName to allow array names like e.g. a(::b)
+	- extended regression test
+	- fixed serializer to handle subobjects of explicitely exported objects
+
+2010-08-09  Gustaf A. Neumann  
+
+
+	- deactivated __next for now
+	- iterated thought doc.tcl-TODOs
+	- fixed path in invocation of xotcl doc script
+
+
+	- moved slottest to library/xotcl
+	- added new Makefile target test-xotcl
+	- finished test migration for now
+
+
+	- moved some more xotcl specfic tests to library/xotcl
+	- transformed forwardtest from xotcl to next
+
+2010-08-08  Gustaf A. Neumann  
+
+
+	- created own directory structure xotcl under library containing
+	  doc, tests, apps, lib etc. and moved obvious content here.
+	- adjusted regression test and old documentation system to work with
+	  new structure
+
+
+	- added redefine-protected to the object template
+	- added methodtype to object template
+	- some documentation updates
+	- some indentation/spacing improvements on xotcl.c
+	- let ".... info method .... METHOD" return values, when METHOD
+	  contains namespace prefix. This can be used to obtain the
+	  parmeter definitions from nx::core
+	- get forward definition from the original command
+
+2010-08-07  Gustaf A. Neumann  
+
+
+	- added @properties and has_property to the documentation
+	  classes. Current primary purpose: define, which methods are
+	  internally-called
+	- added interanlly-called to the method object template
+
+2010-08-06  Gustaf A. Neumann  
+
+
+	- renamed mk_predefined.xotcl -> mk_predefined.tcl
+	- renamed predefined.xotcl -> predefined.tcl
+	- additional subcommand "info method parametersyntax
+	  " returns parameters in a syntax similar to the tcl
+	  man pages
+	- added ability to pass syntax for forwarded methods via set
+	  ::nx::core::signature(::nx::Object-method-forward)
+	  (experimental)
+	- fixed documentation system to work with actual version
+	- added undocumented methods for quality control in documentation
+	- added checks for documented, but unavailable methods in
+	  documentation
+	- added comparison of documented parameters vs. actual parameters in
+	  documentation
+
+2010-08-05  Gustaf A. Neumann  
+
+
+	- changed "Serializer.xotcl" to "serializer.tcl" (package name
+	  from xotcl::serializer to nx::serializer)
+	- added stub for xotcl::serializer for backward compatibility
+	- changed serializer to new namespaces
+	- renamed xotcl.tcl to xotcl2.tcl
+	- added proc finalize to xotcl2.tcl
+
+2010-08-04  Gustaf A. Neumann  
+
+
+	- changed stubs from xotcl to nx
+	- first part of openacs updates
+
+
+	- changed stubs from xotcl to nx
+
+

+
+2010-08-03  Gustaf A. Neumann  
+
+
+	- update of migration guide
+
+2010-08-02  Gustaf A. Neumann  
+
+
+	- minor documentation updates
+
+
+	- renamed tests/method-modifiers.xotcl to
+	  tests/method-modifiers.tcl
+	- changed "require xotcl::test" to "... next::test"
+
+
+	- rename xotcl1.xotcl to xotcl.tcl
+	- some cleanup (version variables, etc.) in xotcl.tcl
+
+
+	- get rid of ":::xotcl::use"
+	- renamed tests based on next from .xotcl to .tcl
+	- extended regression tests
+	- use namespace ::nx::test instead of ::xotcl::test
+	- use namespace ::nx::serializer instead of ::xotcl::serializer
+
+
+	- added minimal stack example
+
+
+	- Implemented "Class info parameter" in Tcl, aliases for xotcl. Now
+	  both definition of parameters and setting of __parameter are in Tcl.
+
+2010-08-01  Gustaf A. Neumann  
+
+
+	- generalized comment removal code in mk_predefined
+
+
+	- change mk_predefined to handle longish comments in predefined.xotcl
+	  (due to documentation system)
+
+
+	- minor typographical changes
+
+
+	- cover different kind of methods and method protection in mirgration
+	  guide
+
+2010-07-31  Gustaf A. Neumann  
+
+
+	- changed one more int to size_t
+
+
+	- use size_t where appropriate
+	- added notnull annotations
+
+2010-07-30  Gustaf Neumann  
+
+
+	- provide error messages for [objectproperty ... type ...]
+	- replace 0 by NULL in calls to GetClassFromObj()
+	- extended regression test
+
+
+	- reanimated "info vars" to show locals in eval method
+
+
+	- removed "[o exists varname]" from next scripting language
+
+2010-07-30  Gustaf A. Neumann  
+
+
+	- updated migration guide
+	- updated TODO
+
+
+	- copied infoObjectMethod and infoClassMethod decls as comments to
+	  xotcl.c, aligned order of method definitions
+
+2010-07-29  Gustaf Neumann  
+
+
+	- renamed varresolutiontest to .tcl
+	- updated TODO
+
+
+	- new function CheckVarName() to check for colons in instance
+	  variable names
+	- unified name-checking in "nx::var import|exists|set"
+	- extended regression test
+
+2010-07-29  ssoberni  
+
+
+	- I created a first draft of the nx language manual, based on the new
+	next::doc facilities. It is still incomplete, but demonstrates the
+	use of next::doc for authoring code documentation.
+	 To re-create the language reference (which is not yet integrated into
+	 the build environment), run:
+	 ./nextsh tests/doc.xotcl
+	 You will then find an output directory "NextLanguageCore" in your
+	 /tmp/ directory.
+	- The next::doc comments which are sourced for generating the manual
+	 can be found in generic/gentclAPI.decls and
+	 generic/predefined.xotcl. I tried to add most comments to the
+	 former, as the complexity of the predefined script does not comfort
+	 documentation comments (and vice versa).
+	- Applied many fixes to the templates (based on the needs of the
+	 language reference)
+
+2010-07-29  Gustaf A. Neumann  
+
+
+	- migration guide overhaul
+
+
+	- define ensemble-like command for accessing instance variables
+	  ::nx::var set ... ::nx::var import ... ::nx::var exists ...
+
+2010-07-28  ssoberni  
+
+
+	Adding the interim logo
+
+
+	- Added a placeholder logo image, to replace the YUI one for the
+	  time being
+	- Provided for giving some version information at either the project or
+	  package level
+
+
+	- Fixed search box and autocompletion support (for packages and
+	  objects)
+	- I allow for selecting/deselecting structural features set
+	  "private" ("deprecated" remains to be done)
+	- I added the generation of links between documentation entities based
+	on {{...}} markers. Any marker (code as well as links) can now be
+	used in both description and parts sections.
+
+2010-07-27  ssoberni  
+
+
+	- Adding basic support for subcommands (a @subcommand part type;
+	  formerly @variant)
+	- Introducing comment reuse and cross-linkage along the class
+	  hierarchy upwards ("subclass of ...", showing inherited
+	  attributes and methods; using a @superclass attribute)
+	- Amending the documentation of @param and @return with "type"
+	  information (checkoptions, constraints, defaults)
+	- Showing both per-class and per-object methods
+	- I now allow for inline- and out-of-line (block) code snippets
+	  in the description sections, based on wiki-like {{{...}}}
+	  marker annotation (same as in scaladoc2).
+	- Adding support for newline representations in description
+	  sections (for a more convenient formatting).
+	- Some bugfixes (e.g., @object-method did not work outside of an
+	  initcmd)
+	- Started refactoring the entity tracing procedure (moving from
+	  [namespace import] resolution to mixin-based creation tracing)
+
+
+	- Adding basic support for subcommands (a @subcommand part type;

+
+2010-07-26  Gustaf Neumann  
+
+
+	- added to git
+
+2010-07-22  Gustaf Neumann  
+
+
+	- don't allow names with namespace separators or colon prefix in
+	  importvar/instvar
+	- provide error message, when method (proc scope) is not found
+	- fix array boundaries for looping on variables in
+	  importvar/instvar
+	- extended regression test
+
+2010-06-23  Gustaf A. Neumann  
+
+
+	- provide spacing in conditional assignments
+
+
+	- fix cleanup of subclasses of metaclasses, keeping metaclass property
+	  (thanks to Stefan for digging into this)
+
+2010-06-18  ssoberni  
+
+
+	 - Added a first set of documentation templates, based on the the
+	  TemplateData engine and the YUI doc styles available from
+	  http://yuilibrary.com/downloads/ (see
+	  library/lib/doc-assets/*.tmpl.html)
+	- Added a @project entity class, which will become the root
+	  concept in a documentation hierarchy. For now, it only serves
+	  for some auxiliary purposes when processing the doc templates.
+	- Continued documenting the next::doc package for testing purposes.
+
+2010-06-16  ssoberni  
+
+
+	 - I made sure that the existing HtmlRenderer infrastructure
+	  remains functional
+	- Added a simplistic templating machinery (see TemplateData), based on
+	cascading [subst] calls in per-object evals (assuming the nonleaf
+	mode) and a basic templating instruction set (i.e., "let", "for", as
+	well as "?" representing if-elseif-else blocks and "include" for
+	composing template fragments). This will help me to transpose the YUI
+	doc templates more easily (and split them up into template fragments).
+	Also, it will allow future documentation writers to provide custom
+	templates or modifications of existing ones. This was somehow inspired
+	by Kristoffer Lawson "templating engine" in his Spindle web framework,
+	which is solely based on Tcl namespaces, however.
+
+2010-06-14  ssoberni  
+
+
+	- Removed @attribute parts and realise them as @param parts which
+	  are parts of @object parts
+	- Renamed PartAttribute->get_part() to require_part()
+	- The line scanner now stores all comment lines as list by using
+	[split] at an early stage to improve the robustness when line strings
+	are fed to list-specific commands.
+
+
+	 - Introduced a PartClass meta-class which seconds Part and its
+	  subclasses (for a uniform id generation etc.)
+	- Removed the kludge around new_from_attribute(), there is now a
+	  canonical new().
+	- "scope" turned into a property of PartAttributes and, as such,
+	  of the association (slot) objects managing parts. this more
+	  closely resembles the idea of per-class and per-object
+	  interfaces. in turn, parts now contain a navigatable
+	  association to their managing part attributes (e.g., to resolve
+	  their scope).
+	- Adding some basic exception-catching infrastructure too better
+	  differentiate between error conditions (style violation,
+	  invalid tags, arbitrary errors emerging from the parsing
+	  machinery). Adjusting and extending the test suite.
+	- Simplified/generalised the parser's tag dispatcher; also, there
+	  is no a general @doc tag which allows to add documentation
+	  lines as tagged parts, rather than a distinct doc block
+	- Removed the tagged_entity mechanisms and per-tag forwards on
+	  EntityClass
+	- Documentation blocks may now contain intermediate space lines
+	  (by adding a space->text transition to the parsing spec).
+	- Adding basic support to trace script sources from [package req]
+	  calls, needs to be polished and refactored
+
+2010-06-05  Gustaf A. Neumann  
+
+
+	- provide explicit error message stating the "substdefault" is
+	  not allowed for setters
+	- don't add "substdefault" a second time, in case it was already
+	  used
+	- never add "substdefault" to methodopts
+	- extended regression test
+
+2010-05-31  ssoberni  
+
+
+	- Renamed EntityFactory to EntityClass
+	- Introduced PartAttribute for managing entity-part associations,
+	  they also protect against duplicate entries
+	- Added NextAttribute (though it should fuse with parameter
+	  entities in the end)
+	- Completed basic support for embedded (initcmd) and freestanding
+	  (script): This multi-stage processing introduces a precedence
+	  order between the commenting levels (script < initcmd < method
+	  bodies).
+	- Renamed most entity classes using their tag equivalent
+	  (@object, ...)
+	- Introduced offset feature for the comment line scanner (offsets
+	  are used to select embedded comment blocks, e.g., in initcmds
+	  or method bodies)
+	- Parsing of arbitrary scripts is now realised in a child interp
+	- Introduced qualified entity names (e.g., @attribute Bar#a1) and
+	  per-object scope (through a scope prefix in tags, e.g.,
+	  @object-method)
+	- Did some cleanup and extended the test suite
+
+2010-05-25  Gustaf A. Neumann  
+
+
+	- minor updates
+
+
+	- fix wording in documentation
+
+
+	- update migration guide from XOTcl 2 to Next
+
+
+	- fix wording in documentation
+
+2010-05-21  ssoberni  
+
+
+	Finished and tested the rewrite of the scanning&parsing front-end for
+	the doc processor. Remains to be integrated with the intermediate @
+	notation (basics are already working)

+	  Upgrading to the ::nx::* namespace renaming
+
+
+	tests/doc.xotcl
+
+2010-05-03  Gustaf A. Neumann  
+
+
+	- changed prefix from "::next::" to "::nx"
+
+2010-04-08  Gustaf A. Neumann  
+
+
+	- updated Changelog
+	- added Annouce files
+
+
+	- updated changelog
+	- deactivated assertions for release
+
+2010-04-07  Gustaf A. Neumann  
+
+
+	- namespace changes: mostly due to marketing reasons, the naming of the
+	top-level namespace changed from "xotcl2" to "next". reasons: xotcl
+	is hard to pronounce for beginners, sounds like "exotic" (but who wants
+	to program in an exotic language) has a certain stigma of strange
+	namings (e.g. "instproc"), is seen as a precursor of tcloo, the
+	top-level namespace ::xotcl2:: is not very nice either, the separation
+	of framework and language is not clear.
+	 We have now:
+	 ::next (the new object system, former ::xotcl2)
+	 ::next::core (framework, primitives)
+	 ::xotcl (former xotcl1)
+	- "::xotcl::use" no longer needed, use Tcl standard mechanisms instead
+	(e.g. "package req next"; "package req XOTcl", "namespace import
+	::next*")
+
+2010-04-06  Gustaf A. Neumann  
+
+
+	- first checkin of doc-tools
+
+2010-04-03  Gustaf A. Neumann  
+
+
+	- undid part of last commit
+
+2010-04-02  Gustaf A. Neumann  
+
+
+	- xotcl 1.6.6: initialize value
+
+
+	- backported part of the deletion logic of xotcl 2.0 to 1.6.6 to avoid
+	  a potential crash with volatile objects
+
+2010-03-31  Gustaf Neumann  
+
+
+	- ::xotcl:.configure: added option "keepinitcmd" to flag, whether or
+	  not initcmds should be kept as instance variables
+
+
+	- remove unneeded attribute for method setter
+
+2010-03-29  Gustaf A. Neumann  
+
+
+	- Allow to speficy last arg of objectparameter to replace scripted init
+	block. The redefinition of objectparameter allows us to specify
+	whether no/some/classical/altered/additional arguments should be
+	allowed during object creation
+
+
+	- Handle cases, where objects/classes are created with the name of
+	preexiting namespaces. Cases, where pre-exisitng namespaces contained
+	classes/objects lead to problems, since xotcl did not see the
+	object/classes of the pre-exiting namespace as children of the new
+	object/class.
+
+2010-03-27  Gustaf A. Neumann  
+
+
+	- backport change from 2.0 to 1.6.6 concerning cylcic dependencies
+	  through namespace imported commands
+
+
+	- fix a potential ordering problem with cyclic dependencies created by
+	  namespace import commands
+
+2010-03-26  Gustaf Neumann  
+
+
+	- fix 64bit problem
+
+
+	- fixed 64bit problem
+
+2010-03-26  Gustaf A. Neumann  
+
+
+	- change library/lib/make.xotcl to xotcl2
+
+
+	- xotcl 1.6.6: backport of memory fixes from xotcl 2.0
+
+
+	- add check for optional match arguments in tcl stub generator
+	- fix potential memory leaks all "definitely losts" from valgrind
+	  (except 24 bytes from Tcl_PkgRequire) gone
+
+2010-03-25  Gustaf A. Neumann  
+
+
+	- minor leak cleanup
+
+
+	- make valgrind + system malloc (instead of tcl malloc) run cleanly
+
+2010-03-23  Gustaf A. Neumann  
+
+
+	- replace hash-lookup in namespace in ObjectHasChildren() by
+	  pointer lookup to reduce namespace dependency.
+	- fix memcopy size
+
+2010-03-22  Gustaf A. Neumann  
+
+
+	- xotcl 1.6.6: one more cases for the packaging, where we want to load
+	  xotcl1 not 2
+
+
+	- xotcl 1.6.6: more cases for the regression test, where we want to
+	  load xotcl1 not 2
+
+
+	- xotcl 1.6.6: make sure to load always xotcl 1 versions when
+	  needed
+	- xotcl 1.6.6: make compilation clean when compiled with assertions on
+
+
+	- remove "buffer" from compiled var structures
+	- remove xotcl1 dependency from aol-tcl
+	- removed conditional var table creation by assertion
+	- make clean compile with assertions turned on
+
+2010-03-19  Gustaf A. Neumann  
+
+
+	- add verbosity for varname copying
+
+2010-03-15  Gustaf A. Neumann  
+
+
+	- rename CallStackPush() to CscInit()
+	- rename CallStackPop() to CscFinish()
+
+
+	- get rid of reminder of tcl 8.4 compatiblity and remove range of
+	ifdefs, such as PRE85, FORWARD_COMPATIBLE, TCL85STACK,
+	CANONICAL_ARGS, USE_COMPILED_VAR_RESOLVER
+
+
+	- removed EXPERIMENTAL_CMD_RESOLVER
+
+2010-03-15  Gustaf A. Neumann  
+
+
+	- handling of minimal object systems. For example, the following three
+	  command create an object system around ::object and ::class ...
+	 ::xotcl::createobjectsystem ::object ::class
+	 ::xotcl::alias ::class + ::xotcl::cmd::Class::create
+	 ::xotcl::alias ::object
+	- ::xotcl::cmd::Object::destroy
+	 ... where no internal message dispatch are used (e.g. no
+	 constructor "init", and where just two methods ("+" and "-")
+	 are used to create and destroy objects
+	- extended regression test
+
+2010-03-14  Gustaf A. Neumann  
+
+
+	- provide prefix for internally called methods to distinguish between
+	  methods called on objects or classes
+
+2010-03-13  Gustaf A. Neumann  
+
+
+	- eliminated XOTE___UNKNOWN
+	- renamed __unknown to requireobject
+
+
+	- eliminated XOTE_UNKNOWN
+
+
+	- eliminated XOTE_RESIDUALARGS
+
+
+	- renamed MethodObj() to XOTclMethodObj() (it is an exported
+	  symbol)
+	- eliminated XOTE_MOVE
+
+2010-03-13  Gustaf Neumann  
+
+
+	- replaced hard-coded method calls for XOTE_DEFAULTMETHOD, XOTE_INIT,
+	  XOTE_OBJECTPARAMETER with MethodObj()
+
+2010-03-12  Gustaf A. Neumann  
+
+
+	- created new functions: ObjectSystemFree(), ObjectSystemAdd(),
+	ObjectSystemsCheckSystemMethod(), ObjectSystemsCleanup(),
+	GetObjectSystem(), CallDirectly() for better separation of systems. We
+	keep track which essential system methods are defined and which which
+	methods are potentially overloaded.
+
+2010-03-11  Gustaf A. Neumann  
+
+
+	- move refcount fixing logic for exit from higher stackframes to new
+	  function: finalObjectDeletion()
+
+
+	- first part of allowing arbitrary named internally called methods.
+
+
+	- fix last issue, with freeing objects, when exit happens from higher
+	  stack frames
+
+2010-03-10  Gustaf A. Neumann  
+
+
+	- block call-stack deletes during XOTCL_EXITHANDLER_ON_SOFT_DESTROY;
+	however, this seems to create a small leak during exit (revant for
+	threads); so currently, debug still turned on
+
+2010-03-09  Gustaf A. Neumann  
+
+
+	- replace all CanInvokeDirectly() by InvokeMethodObj()
+
+
+	- remove some more obsolete RCS Ids
+	- call Tcl_Objs "Obj", not "Object"
+
+
+	- remove filter deactivation to a later point in time (should finally
+	  be before freeAllXOTclObjectsAndClasses())
+
+
+	- deactivate filters in finialize
+	- new method InvokeMethodObj() to replace finally CanInvokeDirectly()
+
+2010-03-08  Gustaf A. Neumann  
+
+
+	- one more change for handling expat dirs n version 1.6.6 (fallback to
+	  bundle)
+
+
+	- handling OBJECT-frames in CallStackPopAll() (for handling exit with
+	  active stack frames)
+
+
+	- one more change for handling expat dirs (fallback to bundle)
+
+
+	- call all truely essential methods directly if possible
+	(Object.destroy, Class.alloc, Class.dealloc, Class.create) The basics
+	of XOTcl can work now also in cases, when these are not defined as
+	methods.
+
+
+	- reduce verbosity
+
+
+	-minor cleanup
+
+
+	- make XOTcl_FrameDecls transparent (use variable declarations in
+	  place instead of the macro)
+	- fix variable shadowing bug in error handling (could cause crashes
+	  when initcmd lead to errors)
+
+
+	- define RecreateObject() for internal call via diect invocation
+	- doCleanup is just called by recreate; merge it into
+	XOTclCRecreateMethod. Is method cleanup necessary? is recreate not
+	sufficient?
+
+2010-03-07  Gustaf Neumann  
+
+
+	- call c-implemented methods directly for XOTE_RECREATE as well
+	  (otherwise, create is faster than recreate)
+
+2010-03-06  Gustaf A. Neumann  
+
+
+	- added stefan's expat library linking extension
+
+
+	- remove unneeded files from repository
+
+
+	- get rid of misleading RCS: lines
+	- passing --prefix to subdirs
+	- regenerated configure files
+
+
+	- added Stefan's expat linking addition for debian
+
+
+	- removed redundant section in configure.in (1.6.6)
+
+
+	- updating tcl.m4 in version 1.6.6 to the actual verison (TEA 3.7)
+
+
+	- removed redundant part from configure.in
+	- regenerated configure
+
+2010-03-05  Gustaf A. Neumann  
+
+
+	- call c-implemented methods directly, when this is safe
+	  (implemented for XOTE_ALLOC, XOTE_CLEANUP, XOTE_CONFIGURE,
+	  XOTE_CREATE, XOTE_DEALLOC); this improves create/destroy speed
+	  by up to 15%
+	- allocate namespaces for objects less eager
+	- make nameing more consistent (change newObj into newObject when
+	  variable is an xotcl object)
+
+2010-03-04  Gustaf A. Neumann  
+
+
+	- fixing "-parameter" with empty content
+	- more variable naming cleanup
+	- fix line breaking in serializer for "exportedObjects"
+
+2010-03-02  Gustaf A. Neumann  
+
+
+	- make sure a childobject ::slot exists after calling "-parameter"
+
+
+	- fix syntax in predefined
+	- let serializer call "init" of attributes, even if it is protected
+
+
+	- use a more recent version of unix/tclAppInit.c
+
+
+	- move pre85 stack specific code into xotclStack.c
+
+
+	- change frametype in "info frame" form bitpattern to symbolic names
+
+
+	- fixed wrong name for per-object filter in RelationSlot
+	- fixed condition in filter-incovation to top-level frames
+	- added frametype to information returned by "info frame"
+
+2010-03-01  Gustaf A. Neumann  
+
+
+	- added an experimental "info frame" handler, which appends "object"
+	  and "class" pairs
+
+
+	- remove dependency from xotcl1 in handling of forwarders in
+	  method "copy"
+	- further cleanup using "CONST char *", improving on naming conventions
+
+
+	- further cleanup using "CONST char *"
+
+
+	- use "CONST char *" in generated interface and below
+
+2010-02-28  Gustaf A. Neumann  
+
+
+	- use "::xotcl::current" instead of "xotcl::self" in predefined
+
+
+	- defined "xotcl::current" as synonym for "::xotcl::self"
+	- new options for ::xotcl::current current object == current
+	  current method == current proc current callingmethod == current
+	  callingproc
+	- "self proc" and friends are for backward compatibility for
+	  xotcl1, "current method" and friends are for xotcl2
+	- namespace exported "::xotcl::current"
+
+
+	- minor cleanup (varresolution test and comment)
+
+
+	- updating tcl.m4 to the actual verison (TEA 3.7)
+
+
+	- removed obsolete generic/xotclAppInit.c
+	- changed loading method in xotclsh from Xotcl_Init() to
+	  Tcl_PkgRequire()
+
+
+	- enable compilation with assertion turned on (via NDEBUG)
+	- fix potentially uninitialized flags for ArgumentCheck()
+	- some further cleanup, tested with 32 bit under Mac OS X 10.6
+
+2010-02-26  Gustaf Neumann  
+
+
+	- keep variables defined from an CMETHOD frame local to this
+	  frame (e.g. initcmd, -nonleaf option, ...); previously
+	  variables without xotcl resolver prefix were defined globally
+	- fix regression test according to previous item
+	- generalize nonXotclObjectProcFrame() and rename it to
+	  activeProcFrame()^
+
+2010-02-25  Gustaf A. Neumann  
+
+
+	- working towards KEEP_VARS_IN_CMETHOD_FRAME
+
+2010-02-24  Gustaf A. Neumann  
+
+
+	- requireNameSpace:
+	  * fix potental crash in requireNameSpace in objscoped methods by
+	  swapping all vartable references in objscopes on stack to the
+	  vartable in the namespace, when it is created
+	- extending regression test
+
+2010-02-23  Gustaf A. Neumann  
+
+
+	- fix for logdir parameter (introduced 10 mins ago)
+
+
+	- renaming of instance variable specific primitiva for more
+	  constistency with ::xotcl::importvar:
+	 ::xotcl::exists -> ::xotcl::existsvar
+	 ::xotcl::setinstvar -> ::xotcl::setvar
+
+
+	- removed XOTclCreateClass() and XOTclDeleteClass(); both are identical
+	  with XOTclCreateObject() and XOTclDeleteObject()
+
+
+	- removed obsolete ::xotcl::configure option "cacheinterface"
+
+
+	- added option "-nonleaf" for method alias
+	- added introspection (for "info method definition") for "alias ...
+	  -nonleaf ..."
+
+
+	- XOTclCallStackFindLastInvocation(): return last scripted
+	  invocation
+	- use xotcl1 in webserver test to make rull regression test
+	  working
+	- make xotcl::use silent
+
+
+	- further naming cleanup
+
+
+	- some more minor cleanup
+
+
+	- cleanup in stack handlers (naming, arguments)
+
+
+	- initcmd: use for initcmds CMETHOD frames instead of OBJECT
+	  stack frames
+	- initcmd: skip parent-stack frame's objscope for initcmd
+	- changed hash-based lookup of children into a cmd-based lookup
+	- extended regression test
+
+
+	- call XOTclObject always "object" instead of "obj"
+
+2010-02-22  Gustaf A. Neumann  
+
+
+	- fixed namespace handling on stack for objects with namespaces
+	  (before, it was possible that a variable was created in an
+	  object's namespace without -objscope)
+	- as a consequence, ListChildren() had to be adjused, since it
+	  depended on the previous namespace handling on the stack
+	- fixed object sesolving in NsDotVarResolver() (before, it was
+	  possible that NsDotVarResolver could create variables in the
+	  wrong namespace)
+	- simplified NsDotVarResolver()
+	- more cleanup in name resolver
+	  * USE_DOT is gone
+	  * XOTclDotDotCmd() removed
+	  * improved performance of InterpCompiledDotVarResolver()
+	  * made LookupVarFromTable() obsolete and removed it
+	  * renamed DotVarResolver() and friends to ColonVarResolver() etc.
+	- extended regression test
+
+2010-02-21  Gustaf A. Neumann  
+
+
+	- replaced in predefined occurances of ::xotcl::is by
+	  ::xotcl::objectproperty
+
+
+	- renamed ::xotcl::valuecheck -> ::xotcl::parametercheck
+
+
+	- defined "info is" as alias of "::xotcl::objectproperty"
+
+2010-02-21  Gustaf A. Neumann  
+
+
+	- renamed old "xotcl::is" -> "xotcl::objectproperty"
+	- renamed old "xotcl::is2" -> "xotcl::is"
+	- we have now is tests for objects in ::xotcl::objectproperty
+	::xotcl::objectproperty $obj object ::xotcl::objectproperty $obj
+	class ::xotcl::objectproperty $obj baseclass ::xotcl::objectproperty
+	$obj metaclass ::xotcl::objectproperty $obj type XXXX
+	::xotcl::objectproperty $obj hasmixin XXXX
+	- "::xotcl::is" is the higher level command,
+	 supporting string contstraints "e.g. upper", user defined type checkers
+	and as well object properties (every parameter type supported for
+	object
+	 and method paameter). Examples:
+	 ::xotcl::is $obj object ?-type $type? ?-hasmixin $mixin?
+	 ::xotcl::is $cl class ?-type $type? ?-hasmixin $mixin?
+	 ::xotcl::is obj metaclass
+	 ::xotcl::is $num integer
+	 ::xotcl::is $string upper
+	- implemented 2nd level reference counting for paramObjType
+
+2010-02-20  Gustaf A. Neumann  
+
+
+	- Unified on c-level "info class-mixin-of" and "info
+	  object-mixin-of" to "info mixinof ?-scope all|object|class?
+	  ?-closure? ?pattern? The former "info class-mixin-of" is now
+	  "info mixinof -scope class"
+	- adapted xotcl1 layer for this change
+	- extended experimental ::xotcl::is2 to handle flags -type and
+	  -hasmixin ::xotcl::is2  object ?-type ? ?-hasmixin ?
+
+2010-02-19  Gustaf A. Neumann  
+
+
+	- experimental checking function ::xotcl::is2 implemented, which
+	generalizes between ::xotcl::is and ::xotcl::valuecheck (it is a
+	valuecheck -nocomplain with an ::xotcl::is syntax and switched
+	arguments)
+
+2010-02-19  Gustaf A. Neumann  
+
+
+	- support for method modifier "object", "protected" and "public" for
+	  method "attribute". One can use now e.g.
+	 Class create C {
+	 :attribute a
+	 :public attribute b
+	 :protected attribute c
+	 :object attribute A
+	 :public object attribute B
+	 :protected object attribute C
+	 }
+	 "protected" and "public" refers to the registered accessor functions
+
+2010-02-18  Gustaf A. Neumann  
+
+
+	- centralize fetching of tcl-obj-types in xotcl_init
+
+2010-02-17  Gustaf Neumann  
+
+
+	- fix namespace in method "case" of "Test"
+	- use Test->case for all tests in parameter.xotcl
+
+2010-02-17  Gustaf A. Neumann  
+
+
+	- new "Test case" method with initblock
+
+
+	- removed the following classes and methods
+	::xotcl::Attribute->check_single_value
+	::xotcl::Attribute->check_multiple_values
+	::xotcl::Attribute->mk_type_checker class ::xotcl::Attribute::Nocheck
+
+
+	- added a version of the "attribute" method to predefined
+
+2010-02-15  Gustaf A. Neumann  
+
+
+	- new methods for MetaSlot to factor out common code: + slotName
+	  (to ease name-construction, care about slot container) +
+	  createFromParameterSyntax: essentially move from
+	  ::xotcl::Attribute to the meta class
+	- test environment: make sure to avoid confusions between the
+	  "namespace" method and command
+
+2010-02-14  Gustaf A. Neumann  
+
+
+	- experimental: allow to show built-in types provided that a)
+	  slot= is specified explicitely, and b) the specified slot is
+	  not the default slot. This should guarantee that we do not
+	  interfere with the predefined converters for the c-level
+	  interface.
+	- incremented ref count on results of all-level converter
+	- extended regression test
+
+2010-02-12  Gustaf A. Neumann  
+
+
+	- ::xotcl::valuecheck: moved "-nocomplain" to first position (similar
+	  to e.g. unset)
+
+
+	- fixed result resetting for user defined converters
+
+2010-02-11  Gustaf A. Neumann  
+
+
+	- implemented "info method definition|parameter|args $name" for
+	  settercmds (with parameter constraints)
+	- extended regression test
+
+
+	- fixed returned method name when setter was used on objects
+	- reduce verbosity
+
+
+	- added parameter "incremental" to ::xotcl::Attribute: when set,
+	  one can use "object paramname add|delete $value" etc.
+	- use setters with parameter constraints in slot optimizer
+	- as a consequence, setting attributes via slot names is about
+	  twice as fast as before, when parameter constraints are used.
+	- extended regression test
+
+
+	- added a "-nocomplain" option to ::xotcl::valuecheck
+	- changed semantic of ::xotcl::valuecheck: per default,
+	  valuecheck raises an error or returns true. If "-nocomplain" is
+	  used, valuecheck returns 0 or 1 like implemented befor this
+	  change
+	- extended regression test
+
+
+	- add comment to converter, make it less verbose
+
+
+	- removed duplciate error message in "hasmixin" converter
+	- fixed refcounting in converting user-types in case of errors
+	- extended regression test
+
+
+	- setterCmd(): Do not allow methodNames start with "-"
+	- setterCmd(): Do not allow defaults for setters
+	- extend regression test
+
+2010-02-10  Gustaf A. Neumann  
+
+
+	- Allowed parameter specification for setters. One can define now
+	  a setter with constraints like e.g. ::xotcl::setter o a:integer
+	  to define a setter named "a" for object "o" which has to be
+	  integer.
+	- Extended regression test
+	- Followed nameing conventions for several structures
+
+2010-02-09  Gustaf A. Neumann  
+
+
+	- bumped version number to 1.6.6
+
+
+	   * provide compatibility with 8.6b1
+
+
+	- fixed compilation for tcl 8.6b1
+
+
+	- fixed valuecheck in connection with modifying converters
+	- extended regression test
+
+2010-02-08  Gustaf A. Neumann  
+
+
+	- made error messages for failed conversions more consistent (note that
+	tcl does not provide the parameter name in the error message, but
+	user-defined converters do)
+
+
+	- clean up comments
+
+
+	- renamed "::xotcl::is ... mixin ..." to "::xotcl::is ... hasmixin ..."
+	  (affects parametertypes as well)
+
+
+	- move methodParameter checkers for "mixin", "baseclass" and
+	  "metaclass" to predefined.
+	- deactivated checkMethods in gentclAPI.decls and in xotcl.c
+
+
+	- provide error message for cases, where parameter options are not
+	  allowed (or ignored)
+
+
+	- fix counter initialization in ::xotcl::importvar
+	- register alternate "new" method in "contains" for xotcl2 and (if
+	  available) for xotcl1 objects
+
+2010-02-07  Gustaf A. Neumann  
+
+
+	- streamline quoting in regression test
+
+
+	- handle multivalued + values converted viaCmd converter the new output
+	  list is only built when needed via ArgumentCheckHelper()
+
+2010-02-05  Gustaf Neumann  
+
+
+	- added argument for converter to return the converted tcl_obj, which
+	should be passed on (currently only used for viaCmd); this way, we
+	could remove the kludge of querying the converter after the conversion
+	for special handling.
+
+
+	- treat currently unknown converters in valuecheckcmd as error
+	- fix the regression test from the last changes
+
+
+	- added parameter option slot= to pass slotobj to a certain
+	  parameter
+	- use slot option to keep relation between parameter and slot
+	- object parameter dispatch type checker on slot objects
+	- allow transformation via user-defined converter (can be use to
+	standardize parameter values) experimental implementation,
+	refcounting has to be looked in detail, maybe we need a different
+	interface for the converters
+
+2010-02-04  Gustaf Neumann  
+
+
+	- added error message when substdefault is specified without a
+	  default value
+	- extend regression test
+
+2010-02-03  Gustaf Neumann  
+
+
+	- predefined.xotcl: move toParameterSyntax and objectparameter to
+	  a position, where basic slot definitions are provided
+	- fixed default value setting in bootstrap code
+	- provide more precise error message in converter, when object
+	  type are used
+	- extend regression test
+
+
+	- get rid of convertToObjectOfType(), make convertToClass() and
+	  converterToObject() more general, accepting type constraints
+
+2010-02-02  Gustaf Neumann  
+
+
+	- support for all string constraints provided by "string is ...
+	  $value" in object and method parameters ("alum", "alpha", ...,
+	  "xdigit"). Technically, these types are tclobjs (using
+	  converter convertToTclobj) having pParm->converterArg set to
+	  the constraints.
+	- extended regression test
+
+2010-01-29  Gustaf A. Neumann  
+
+
+	- moved slot optimizer from ::xotcl::ObjectParameterSlot::Optimizer to
+	  ::xotcl::Attribute::Optimizer
+
+
+	- refactor Slot class hierarchie
+	- new methods in ObjectParameterSlot "toParameterSyntax" and
+	  "createFromParameterSyntax"
+	- some more cleanup
+	- removed legacy syntax for "-parmeters"
+
+2010-01-28  Gustaf A. Neumann  
+
+
+	- cleanup of legacy stuff in slot management.
+	  * merged InfoSlot and InterceptorSlot into RelationSlot
+	  * get rid of legacy "mixin set ...." command
+	- renamed "parameterSlot" into "methodParameterSlot" to avoid potential
+	  confusions
+
+
+	- define everything concerning basic slot setup in a single
+	  "namespace eval ::xotcl {...}"
+	- undefine ::xotcl::createBootstrapAttributeSlots after this block
+	- fix default DefaultSuperClass() with isMeta==1 in cases, where
+	  we are already at the root meta class
+	- use "-parameter" in xotcl1 instead of createBootstrapAttributeSlots
+
+2010-01-27  Gustaf Neumann  
+
+
+	- name parameterType -> parameterSlot
+	- use for now same parameterSlot for xotcl1 + 2
+	- disallow unknown types (otherwise interpreted as user-types) in
+	  valuecheck
+
+2010-01-26  Gustaf A. Neumann  
+
+
+	- allow syntax "object,type=::SomeClass" and
+	"class,type=::SomeMetaClass" (currently identical, we should as well
+	check for class/meta-class in case of "class,type=SomeClass")
+
+2010-01-25  Gustaf A. Neumann  
+
+
+	- remove unneeded push and pop operations in ListChildren() and
+	  ObjectHasChildren()
+
+
+	- name XOTclObjects always "object" instead of "obj" to avoid potential
+	  confusion with Tcl_Objs
+
+
+	- support for parameter spec of form "type=XXX" to denote that
+	  the parameter must be an object of the specified type (class;
+	  directly or indirectly)
+	- new built-in converter: convertToObjectOfType()
+	- keep parameterObj (source for conversion to XOTclParam) for
+	  making introspection less work. However, this is only used for
+	  XOTclParams generated via ParamParse().
+	- extending regression test
+
+2010-01-24  Gustaf A. Neumann  
+
+
+	- pass arg from objectparameter as first argument to objparms (similiar
+	  to client data)
+
+
+	- parameterFromSlot returns now pair object-param & method-param
+	- define dissallowed parameter options for object parameter,
+	  method parameter and valuecheck command
+	- make canonical table of parameter options (currently in
+	  tests/parameter.xotcl)
+	- extend regression test
+
+
+	- new cmd "::xotcl::valuecheck  " where
+	  "valueConstraints" is whatever is allowed in e.g. parameters
+	  (including user defined types)
+	- new Tcl_ObjType "xotclParam"
+
+2010-01-23  Gustaf A. Neumann  
+
+
+	- checking multivalued types in "-parameters" by using argument
+	  checker
+	- some cleanup
+	- extend regression test
+
+
+	- added "multivalued" to parameter options
+	- made error message produced by XOTclObjErrType look like Tcl's
+	  error messages
+	- extended regression test
+	- test utility: changed "?" to return error msg in case of error
+
+
+	- don't run multiple queries in "??"
+	- fixed last changes to regression test as usual
+
+2010-01-22  Gustaf A. Neumann  
+
+
+	- new function ::xotcl::parameterFromSlot (used in argument
+	  checker as well)
+	- use ::xotcl::forward in Slot constructor (instead of dispatch)
+	- checking methods on slots for single- and multivalues slots
+	  (can be optimized)
+	- extended regression test
+
+2010-01-21  Gustaf Neumann  
+
+
+	- added instance variable arg for interfacing with parameter
+	  interface. "arg" acts like a clientdata for type converter
+	- added multiple parameter options handling to method "parameter"
+	  to obtain similar functionality from object parameters as from
+	  method parameters
+	- added conveniance method "??" to test to indicated test that
+	  should fail with an error
+	- added severy type converters to achieve same object type
+	  checking as in ::xotcl::is (these are currently in the
+	  regression test, should move finally into predefined.xotcl)
+	- extended regression test
+
+2010-01-19  Gustaf A. Neumann  
+
+
+	- making methodDefinitions NULL terminated
+	- passing optional arg to user-defined argument converter
+	- refuse to redefine type converters for a single parameter
+	- adding regression test for parameters
+
+2010-01-15  Gustaf A. Neumann  
+
+
+	- experimental change of resolver name prefix char from dot to single
+	  colon
+
+2010-01-14  Gustaf A. Neumann  
+
+
+	- extended migration guide
+	- defined eval in predefined via "-nonleaf", used at various
+	  places
+	- added "info mixinof ?-scope all|object|class? ?pattern?",
+	  dropped "object-mixin-of" and "class-mixin-on" from registerd
+	  method
+	- extended regression test
+	- xotcl1: make "-volatile" invoked via unknown behave correctly
+
+2010-01-11  Gustaf A. Neumann  
+
+
+	- keep orignial objc/objc in call stack context such that
+	  next/self args works with canonical args (allow e.g. different
+	  order of nonpos args in a next)
+	- make naming in xotcl.c more consistent
+	- ensure to return empty, when "info callable -which" fails
+	- extend regression test
+
+
+	- add calltype to tcl85showStack
+
+
+	- Serializer: include ObjectSystemSerializer in "Serializer all"
+	- Serializer: use class-mixin in dependency order
+	- Serializer: add appropriate "::xotcl::use xotcl1|xotcl2"
+	- Serializer: fix syntax in exportMethods
+	- Serializer: provide limited support for exporting aliases for xotcl1
+	  objects
+
+2010-01-09  Gustaf A. Neumann  
+
+
+	- NsDotVarResolver: don't create variables on CMETHOD frames when their
+	  names do not start with a "."
+	- general overhaul of XOTcl_PushFrame()XOTcl_PopFrame():
+	 new functions:
+	   * XOTcl_PushFrameCsc()/XOTcl_PopFrameCsc(): for CMETHOD fames
+	   * XOTcl_PushFrameObj()/XOTcl_PopFrameObj(): for OBJECT frames
+	 (objscope)
+	- preallocate obj->vartable in XOTcl_PushFrameObj() to
+	 avoid situations where to non-existing vartable is created
+	 on demand at different places (e.g. on stack and in
+	 var resolver)
+	- caller of convertToRelationtype(): make sure that last argument
+	 keeping the result is large enough to held pointer (in case of
+	 sizeof(void) != sizeof(int)
+
+2010-01-08  Gustaf A. Neumann  
+
+
+	- use uplevel in slot add/delete to evalute in calling namespace
+	  (for not fully qualified object names)
+	- determine namespace in test method "?" to allow its execution
+	  in an "namespace eval"
+	- added regression tests
+
+
+	- extend regression test
+
+
+	- make sure to have an xotcl frame pushed, when byte-code-compiler is
+	invoked. This is necessary for providing the context for dotCmd
+	resolvers
+
+
+	- improved naming of resolvers: use InterpDot*Resolver and
+	  NsDot*Resolver for interp wide and namespace specific resolvers
+	- added possibility to escape the call of commands starting with a dot
+	  from method bodies by prefixing with a second dot.
+
+
+	- make allocation sizes for dynamically allocated
+	  parameterContexts consistent between alloc and realloc
+	- added sanity check in getAllClassMixinsOf() It seems as it would be
+	possible with __defaultSupeclass to define a class which has itself
+	als a subclass. Just a quick fix, we have investigate more on this.
+
+2010-01-07  Gustaf A. Neumann  
+
+
+	- serializer: move checking of the requested objects to be
+	  exported to the invocation of "Serializer all"
+	- replace "namespace import ::xotcl::*" by "xotcl::use xotcl1"
+
+
+	- improved comments
+
+2010-01-06  Gustaf A. Neumann  
+
+
+	- added option "objectsystems" to ::xotcl::configure to obtain
+	  the currently defined object systems
+	- added option "baseclass" to ::xotcl::is to check, whether a
+	  class is a baseclass of an object system (root class or root
+	  meta-class of object system)
+	- changed result of "... info methods -methodtype scripted" to
+	  return only truely scripted methods (no aliases)
+	- some more cleanup in regression tests
+	- first version of serializer for xotcl1 + xotcl2
+
+2010-01-05  Gustaf A. Neumann  
+
+
+	- modernize test a little: all local definitions of proc "?" are
+	  gone.
+	- added interface to test: "Test parameter count SOMEVALUE" to
+	  specify conveniently e.g. the number of tests the be executed
+	- add XOTCL_CM_NO_UNKNOWN to dispatch of defaultmethod
+
+
+	- added "info method" to migration guide
+
+
+	- added option "-application" to "info callable" to omit methods
+	  from base classes
+	- extended regression test
+	- changed naming of methodtype "system" to "builtin"
+	- added "info methods" to migration guide
+
+
+	- xotcl.c: removed all names starting with "inst" (exception: instvar)
+
+
+	- added option "arg=.." to parameter options; this argument can
+	  be passed to converter; used currently for "type=relation" to
+	  flag, that the relation type is different from the parameter
+	  name
+	- extended "objectparameter" to handle such cases
+	- removed relationtypes "mixin", "filter", "instfilter" and "instmixin"
+	  since not needed due to converterArg
+
+
+	- removed all unreferenced entries from XOTE_*
+	  - regrouped XOTE_* for easier comprehension
+	  - used XOTE_* on more occations
+	- used XOTclCallCommand() for calling Tcl "format" and "interp"
+
+
+	- removed XOTclInstVar from the C-level API. todo: add all xotcl*cmds
+	  to C api, including importvar
+
+
+	- changed resultss of "filtersearch" and "self next" to new
+	  naming Caveat: for xotcl1, there is no mapping for the names to
+	  the old style in "self next" and "self filterreg"
+	- backwards compatible mapping of filterseach in xotcl1
+
+2010-01-04  Gustaf A. Neumann  
+
+
+	- removed dependency on proc/instproc in copy/move. code is now
+	  independet of class system
+
+
+	- allow invovation of fully qualified method names (determined via ...
+	  info method name ...)
+
+
+	- moved cmd flags into xotclInt.h
+	- added missing prototype
+
+
+	- added interface definitions for generated tcl commands to xotcl.c
+
+2010-01-04  Gustaf A. Neumann  
+
+
+	- added experimental flag for alias "-noleaf" to force a stack frame to
+	be written (e.g. necessary for "next"). makes only sense for aliases
+	to c-implemented cmds
+	- fix inconsistent behaviour of dotVarResolver
+	 "o eval {set .x 1}" was setting var ".x" instead of "x"
+	 The problem was due to a interaction between
+	 the namespace varResolver() and the DotVarResolver()
+	- fix for DotCmdResolver during compilation of a proc by Tcl.
+	- extended regression text
+	- found 2 potential bugs (not fixed yet)
+
+2010-01-04  Gustaf A. Neumann  
+
+
+	- moved "-per-object" consequently immediately after obj in the
+	following commands : ::xotcl::alias, ::xotcl::methodproperty,
+	::xotcl::setter to achiev conformance with ::xotcl::forward and
+	::xotcl::method
+
+2010-01-03  Gustaf A. Neumann  
+
+
+	- reduce verbosity
+
+
+	- added ::xotcl::forward as cmd instead of method now, all
+	method-defining-methods (alias, method, forward, setter) are defined
+	as cmds (this should make life of serializer easier)
+
+
+	- added ::xotcl::method as cmd instead of methods object-method and
+	  class-method
+
+
+	- added ::xotcl::exists as cmd
+
+
+	- minor refactoring
+
+
+	- made some more xotcl2 methods protected (no big need to call these
+	  from different objects): unknown, uplevel, upvar
+
+2010-01-03  Gustaf A. Neumann  
+
+
+	- changed assertions: old (xotcl1) interface: 3 methods + 3 info
+	  methods
+	  *  check Options
+	  *  info check
+	  *  invar Conditions
+	  *  info invar
+	  *  instinvar Conditions
+	  *  info instinvar
+	 new (xotcl2) interface: 1 cmd (similar to ::xotcl::relation)
+	 ::xotcl::assertion check|object-invar|class-invar ?arg?
+	- added emulation for xotcl1
+	- deleted namespecific C macros:
+	isInfoString, isInstinvarString, isInvarString, isInstprocString,
+	isProcString
+
+2010-01-02  Gustaf A. Neumann  
+
+
+	- added method "eval" on ::xotcl2::Object
+	- used "o eval {....}" as generic method to apply commands/methods to
+	  other objects
+
+
+	- change and rename cmd instvar ::xotcl::instvar -object someObject
+	newVar into ::xotcl::importvar someObject newVar Rationale of change:
+	only needed in xotcl2 for importing variables from different objects
+
+
+	- handle HAVE_UINTPTR_T like HAVE_INTPTR_T
+	- use ::xotcl::setinstvar instead of ::xotcl::setinstvar in serializer
+
+
+	- use INT2PTR and PTR2INT macros in generated stubs
+
+
+	- update to TEA 3.7 (from TEAD 3.5)
+	- use of INT2PTR to avoid warnings about different sizes on 64bit
+	  architectures
+	- defined HAVE_INTPTR_T as a macro to make definition of INT2PTR working
+
+2010-01-01  Gustaf A. Neumann  
+
+
+	- changed level of headings
+
+
+	- added headings for parameter sections
+
+
+	- first skeleton of migration guide
+
+
+	- renamed "ClassName info instmixinof ?-closure? ?pattern?" into
+	  "ClassName info class-mixin-of ?-closure? ?pattern?"
+	- renamed "ClassName info mixinof ?-closure? ?pattern?" into
+	  "ClassName info object-mixin-of ?-closure? ?pattern?"
+	- added emulation "ClassName info instmixinof|mixinof" for xotcl1
+
+
+	- add minor comment
+
+
+	- reactivated XOTclErrInProc()
+
+
+	- get rid of rst->deallocCalled (not needed due to reference
+	  counting on xotcl objects)
+	- reduce verbosity
+
+
+	- added existence test for slot extractor (needed for 8.5.8)
+	- added refcounting CallStackDoDestroy() to ensure existance of
+	  object until end of function
+	- make sure to call PrimitiveDestroy() before
+	  DeleteCommandFromToken(), otherwise e.g. unset traces on this
+	  object cannot be executed
+	- regression test works again
+
+2009-12-31  Gustaf A. Neumann  
+
+
+	- added refounting in ObjectDispatch() to make sure, obj survives until
+	  the end of the function
+
+
+	- comment manual call to DoDealloc() in case the method has failed
+
+
+	- handle change in tcl 8.5.8:
+	  http://tcl.cvs.sourceforge.net/viewvc/tcl/tcl/generic/tclObj.c?sortby=date&r1=1.139.2.1&r2=1.139.2.2&pathrev=core-8-5-branch in xotcl:
+	  * when e.g. the parent namespace is deleted with a "namespace
+	  delete", the change above causes, the no xotcl methods could be
+	  resolved (and called) anymore.
+	  * therefore, e.g. a "C dealloc c1" did not work, since dealloc
+	  passes c1 via tcl_obj, and the tcl_obj is as well converted to
+	  an xotcl object via Tcl_GetCommandFromObj(), which fails as
+	  well.
+	- to bypass this problem, xotcl has now a C-function DoDealloc(),
+	  which is called, when this situation is detected.
+	- some more cases, where xotcl could reference already freed
+	  memory were fixed (thanks to enable-symbols=mem)
+	- as collateral damage, parts of the regression test don't work
+	  currently
+
+2009-12-30  Gustaf A. Neumann  
+
+
+	- space changes
+
+
+	- made naming more consisent
+	- alway initialize parse context properly
+
+2009-12-29  Gustaf A. Neumann  
+
+
+	- updated tutorial further
+
+
+	- updated first part of tutorial to xotcl2 syntax
+	- fixed examples in tutorial
+	- added soccerClub2.xotcl
+
+
+	- fix example in the tutorial
+
+
+	- new subcommand "... info method body ..." to avoid to relay on syntax
+	  of "info method definition" in xotcl1 compatibility
+
+
+	- removed -per-object from ::xotcl::relation
+	- removed -per-object from methods "mixinguard" and "filterguard"
+	- removed -per-object from methods "alias" and "method"
+	- added "... object filterguard ..." and "... object mixinguard
+	  ..."
+	- implemented "info method definition" with "object" modifier
+	- extended regression test
+
+2009-12-28  Gustaf A. Neumann  
+
+
+	- call __UNKNOWN with XOTCL_CM_NO_PROTECT (don't complain when it is
+	  protected)
+
+
+	- added " object filter" and " object mixin"
+	- use explicit "(object|class)-(mixin|filter)" relations in
+	  ::xotcl::relation
+	- removed "-per-object" from all user-level relation commands
+	  (::xotcl::relation has still "-per-object"), but it is not
+	  needed anymore
+	- register slots "object-mixin" and "object-filter" for conveniance to
+	allow object-filter and object-mixins via configuration via object
+	parameter
+
+
+	- turned "setter" method into a command "::xotcl::setter" with
+	  the same interface like "::xotcl::alias"
+	- removed flag -per-object from XOTclCForwardMethod
+	- require "object" to be followed directly by either method defining
+	command or info, etc. (use "public object method" instead of "object
+	public method")
+
+2009-12-26  Gustaf A. Neumann  
+
+
+	- renamed method property "static" to "redefine-protected"
+
+
+	- removed "-protected" and "-public" from method defining methods
+	  ("alias", "method")
+
+
+	- Definition of method modifiers "public", "protected" and
+	  "object"
+	- all method-creating methods ("method", "alias", "forward",
+	  "setter") return now the fully qualified method names
+	- extending 50 regression tests fpr method modifiers
+	- Make "unknown" for ::xotcl2::Class" to raise an error instead of
+	warning. Otherwise, protected class-level methods would create
+	objects with the name of protected methods. Other option: make calls to
+	protected methods raise an error, instead of calling "unknown"
+
+2009-12-23  Gustaf A. Neumann  
+
+
+	- return fully qualified name from method defining commands (part 1,
+	  "method")
+
+2009-12-22  Gustaf A. Neumann  
+
+
+	- changed in xotcl-core "method" into "object-method" and
+	  "class-method", provided scripted definition for method in
+	  xotcl2
+	- removed "setter" from methods in xotcl1
+	- defined xotcl1 methods in terms of "proc" and "instproc"
+
+2009-12-21  Gustaf A. Neumann  
+
+
+	- dropped method "instvar" from the xotcl2 interface
+
+
+	- Methods defined via "method" are now per default "protected"
+	- new switch "-public" for "method" to define public methods

+	  "all|protected|public"
+	- new flag for "info methods": -callprotection", values
+	  "all|protected|public"
+	- converted part of regression test
+
+
+	- minor refactoring to reflect changes in "info methods"
+
+2009-12-19  Gustaf A. Neumann  
+
+
+	- changed "info methods" (without defined, as defined in xotcl1)
+	  into "info callable"
+	- changed "info methods -defined" into "info methods"
+	- replaced "procsearch " by "info callable -which "
+	- added emulation for procsearch for xotcl1
+
+2009-12-18  Gustaf A. Neumann  
+
+
+	- removed "obj|class info alias"; obsoleted by "info method definition"
+
+
+	- renamed "info method pre" to "info method precondition"
+	- renamed "info method post" to "info method postcondition"
+
+
+	- removed "-per-object" slot from infoslot->get and infoslot->add
+
+
+	- reduce verbosity
+
+
+	- added changes for new behavior
+
+
+	- keep last setting of per-object and per-class mixins, when list of
+	new mixins contains invalid ones (prev. versions: registered mixins
+	were reset)
+
+
+	- reseting interceptor list in interceptorslot->mixin via relation
+	- adding rests for behavior, when setting invalid mixins
+
+2009-12-17  Gustaf A. Neumann  
+
+
+	- remove experimental code
+
+
+	- info "pre" is gone, now subcommand " info method pre
+	  ", added emulation in xotcl1
+	- info "inst pre" is gone, now subcommand " info method pre
+	  ", added emulation in xotcl1
+	- info "post" is gone, now subcommand " info method post
+	  ", added emulation in xotcl1
+	- info "instpost" is gone, now subcommand " info method post
+	  ", added emulation in xotcl1
+	- "info instinvar" gone, added emulation in xotcl1
+
+
+	- minor cleanup of obsolete code
+
+
+	- removed deprecated calls from predefined and regression test
+
+
+	   * info params removed
+	  * info instparams removed
+	  * added subcommand to "info method args ": similar to "info
+	method parameter ...", but returns only names of parameters instead
+	of full parameter definitions
+
+
+	- method "instfilterguard" is gone (for xotcl2) we have now
+	  " filterguard  ... " " filterguard
+	  ?-per-object?  "
+	- added emulation for old "filterguard" and "instfilterguard" in xotcl1
+
+
+	- "info instforward" gone, added emulation in xotcl1

+
+
+	- "info instfilter" gone, added emulation in xotcl1
+
+
+	- "info instmixinguard" gone, added emulation in xotcl1
+
+
+	- "info instmixin" gone, added emulation in xotcl1
+
+
+	- provide method get for Interceptor slots
+	- added tests/info-method.xotcl
+	- added tests/interceptor-slot.xotcl
+
+
+	- handling forward case with nonpos-arg and zero positional
+	  arguments (many thanks to Stefan)
+	- treating "-per-object" in infoslot get method (many thanks to
+	  Stefan)
+	- removing obsolete function from xotcl.c
+
+2009-12-16  Gustaf A. Neumann  
+
+
+	- method "instmixinguard" is gone (for xotcl2) we have now
+	  " mixinguard  ... " " mixinguard
+	  ?-per-object?  "
+	- added emulation for old "mixinguard" and "instmixinguard" in xotcl1
+	- xotcl1: defined "parametercmd" and "instparametercmd" in terms of
+	 alias instead of forward
+
+2009-12-15  Gustaf A. Neumann  
+
+
+	- forward: new option for handling flags syntax "%-SOMEFLAG ?insert?%"
+	The option checks the actual arguments, if they start with "-", it
+	compares it with the provided name. If it matches, the flag is consumed
+	and added at the provided position in the output list. If the flag does
+	not match, but "insert" is given with the value of 1, then the flag is
+	output as well. Note that the last feature is added for omitting double
+	inserts.
+	- due to the new forward option, the following important
+	 cases work now:
+	 - adding/deleting/... per-object mixins for classes via
+	 slot methods
+	 C mixin -per-object add M
+	 - adding per-object mixins for classes in short form
+	 C mixin -per-object M
+	- added "what" argument to deprecated command to let the
+	 user be more exact, what is actually deprecated
+
+2009-12-01  Gustaf A. Neumann  
+
+
+	- new XOTclClassInfoMixinMethod (will replace
+	  XOTclClassInfoInstmixinMethod)
+	- adding some tracing for handling "mixin" in relation cmd and
+	  info methos for now
+	- removed registry of instmixin and instfilter for xotcl2
+
+2009-11-30  Gustaf A. Neumann  
+
+
+	- moving definitions to the right place
+	- added "-per-object" to XOTclRelationCmd
+	- skipping "mixin" and "filter" in ::xotcl::parametersFromSlots
+	  for xotcl1 objects
+	- added parameter "forward-per-object" to slots in order to flag
+	  whether "per-object" should be passed via the forwarder
+	- new function MethodTypeMatches() for filtering on methodtypes
+	- provide faster lookup when pattern for info methods does not contain
+	  meta characters
+
+2009-11-16  Gustaf A. Neumann  
+
+
+	- updated changelog
+
+2009-11-11  Gustaf A. Neumann  
+
+
+	- removed "-per-object" from " info alias"
+
+
+	- xotcl2: implemented " info -per-object subcmd" (moved
+	  "-per-object" in front of info, since it specifies, what kind
+	  of info is requested). As a consequence,
+	  XOTclObjInfoMethodMethod() works returns always object specific
+	  infos and XOTclClassInfoMethodMethod() class specific infos, no
+	  "-per-object" switch for the subcmd required.
+	- cleanup in other subcomds than "info method" and "info methods"
+	  required
+
+
+	- gentTclAPI: create every converter only once.

+	  "
+	   * "info method definition" returns full cmds
+	 (e.g. for scripted methods parameters, body, pre- and postconditions)
+	   * fixed proper list handling in AssertionList()
+	   * added tests for "info method" (infomethodtest.xotcl)
+	- changed method "alias" in xotcl2:

+	 ".... -cmd -source-object -source-method -source-per-object:switch"
+	   * determine method cmdname via "... info method name "
+	 and pass it to alias
+	- method "parametercmd" and "instparametercmd" are gone (for xotcl2)
+	 we have now
+	 " setter "
+	 " setter ?-per-object? "
+	- added emulation for old "parametercmd" and "instparametercmd" in
+	  xotcl1
+	- method "instforward" is gone (for xotcl2),

+	  invokeCmdMethod()
+	- renamed DoCallProcCheck() into InvokeMethod()
+
+2009-08-17  Gustaf A. Neumann  
+
+
+	- removed XOTclCallStack definition and datastructures, when compiled
+	  with TCL85STACK
+	- CallStackPop(): when compiled with TCL85STACK,
+	 the function just initializes a given call stack content;
+	 allocation based on C-Stack
+	- some function cleanup and minor optimizations
+
+2009-08-14  Gustaf A. Neumann  
+
+
+	- added option withRootClass to ComputePrecedenceList();
+	- exclude rootClass in search for defaults (for the time being)
+	- implemented cmd ::xotcl::instvar
+
+2009-08-13  Gustaf A. Neumann  
+
+
+	- get rid of fakeNS
+	- minor simplification in XOTcl_PopFrame()
+
+
+	- Removed currentFramePtr (the pointer from the xotcl stack to the tcl
+	stack) from the call stack content. Now, all access to the call stack
+	content happens via the tcl85stack.
+	- For the time being, the xotcl stack is purely an allocation stack
+	(we still have to evaluate, where we should store the call stack
+	content efficiently:
+	some options: via alloca, on the c-stack, on the tcl stack, on an
+	allocation stack)
+
+
+	- new method CallStackPopAll() for making ExitHandler() independent
+	  from call stack structures
+
+
+	- implemented doCleanup() independent from stack structures
+	- some variable renaming
+
+
+	- renamed UndestroyObj() to CallStackMarkUndestroyed() and implemented
+	  it for tcl85stack
+
+
+	- get rid of CallStackIsDestroyed()
+
+
+	- move tcl85showStack(), nonXotclObjectProcFrame() and
+	  nextFrameOfType() to xotclStack*.c
+
+
+	- get rid of GetSelfProc()
+	- implemented XOTclNextMethod() for tcl85stack
+
+
+	- implemented XOTclForwardMethod () for tcl85stack
+
+
+	- return Tcl frame pointer as last arguments in
+	  CallStackGetFrame() and CallStackGetTopFrame()
+	- pass call stack content to GetSelfProc()
+	- some simplifications to avoid multipe stack searches
+	- implemented XOTclSelfSubCommand () for tcl85stack
+
+
+	- implemented FilterActiveOnObj() for tcl85stack
+
+
+	- pass conditionally XOTclCallStackContent to GuardCall() due to
+	  different stack lifetime
+	- CallStackPush() returns now callstack content
+	- implemented CallStackFindActiveFilter() for tcl85stack
+
+
+	- implemented computeLevelObj() for tcl85stack
+
+2009-08-12  Gustaf A. Neumann  
+
+
+	- implemented CallStackUseActiveFrames() for tcl85stack
+	- nonXotclObjectProcFrame returns now only active frames
+
+2009-08-11  Gustaf A. Neumann  
+
+
+	- implemented XOTclCallStackFindActiveFrame() for tcl85stack
+
+
+	- defined new (3rd) frame type FRAME_IS_XOTCL_CMETHOD for calling
+	  c-implemented methods (the same as FRAME_IS_XOTCL_OBJECT,
+	  except that it uses csc as clientData instead of only the xotcl
+	  object
+	- implemented XOTclCallStackFindLastInvocation() for tcl85stack
+
+
+	- pass call stack content explicitly to
+	  canonicalNonpositionalArgs to obtain active class or object
+	- fix two more regression test entries with canonical args (info
+	  body, order in info locals)
+	- canonical args passes now regression test (also in connection with
+	  tcl85stack)
+
+
+	- pass call stack content explicityl to XOTclNextMethod, which is
+	  used on one occurance outside the tcl callstack scope, such
+	  that CallStackGetTopFrame() gets the previous stack entry
+	- implemented CallStackGetTopFrame() for tcl85stack
+	- implemented CallStackGetObjectFrame() for tcl85stack
+
+2009-08-10  Gustaf A. Neumann  
+
+
+	- new function CallStackDestroyObject() to factor out xotcl stack
+	access Since tcl-stack-entries have a lightly different life-time
+	(pop is managed by tcl), we have as well slightly different life-times
+	of objects. One test in the test suite is deactivated for now, we will
+	see, if this turs out to become a problem as we proceed.
+
+
+	- new function CallStackClearCmdReferences() to factor out xotcl stack
+	  access
+
+
+	- moved stack procs into new files xotclStack.c and xotclStack85.c
+	- based CallStackGetFrame() in addition to GetSelfObj() to new
+	  stack structure, when TCL86STACK is defined
+	- fixed error and warning message for failed assertions to avoid access
+	  to the xotcl stack
+
+
+	- follow naming conventions for defines TCL85STACK_TRACE
+	- deactivate CANONICAL_ARGS for the time being
+
+
+	- Stefan implementation for args with canonical args
+	- canonicalNonpositionalArgs() receives explicit current xotcl object
+
+2009-08-09  Gustaf A. Neumann  
+
+
+	- remove debug output
+
+2009-08-09  Gustaf Neumann  
+
+
+	- rename variable "ns" (namespace pointer) to "nsPtr" for tcl naming
+	  compliance
+
+
+	- simplified callingNameSpace() significantly (works with and
+	  without TCL85STACK the same way)
+	- simplified GuardCall (removed argument push)
+	- removed unneeded functions, reduced tracing
+
+2009-08-09  Gustaf A. Neumann  
+
+
+	- snapshot 3
+	- first version passing regression test again
+
+2009-08-07  Gustaf A. Neumann  
+
+
+	more trace
+
+
+	- snapshot #2
+
+2009-08-06  Gustaf A. Neumann  
+
+
+	- starting to use tcl85 stack (when complied with TCL85STACK).
+	  Goal is to remove the own stack handling, when compiled with
+	  Tcl 8.5+ Introduced two frame types, FRAME_IS_XOTCL_METHOD and
+	  FRAME_IS_XOTCL_OBJECt
+	- Currently, only self is resolved this way from the Tcl stack.
+	- Currentlsy, just parts (e.g. testo.tcl) of the regression test work
+
+2009-08-05  Gustaf A. Neumann  
+
+
+	- updating changelog
+	- cleanup and documentation in xotcl.c
+
+
+	- cleanup of arguments in makeproc (Stefan Sobernig)
+
+
+	- finishing unset unspefied values in nonpos arg passing under
+	canonical args, when a nonposarg has no default, and the parameter is
+	not required, we have to unset the dummy default value. Since causes
+	some overhead, since unset is done via ::xotcl::unsetUnknownArgs
+
+2009-08-04  Gustaf A. Neumann  
+
+
+	commit snapshot
+
+2009-08-03  Gustaf Neumann  
+
+
+	- releasing dynamically allocated parse contexts
+	- tried to reduce overhead of method invocation when no nonposArgs are
+	  used, but failed, sind proc has neither flags not clientData
+
+2009-07-29  Gustaf Neumann  
+
+
+	- make ifdsize explicit (stubcode generator)
+	- new method parseContextInit(), will be used for variable sized
+	  interfaces (for nonpos arg parsing)
+
+2009-07-28  Gustaf Neumann  
+
+
+	- first implementation of canonical arguments
+
+2009-07-24  Gustaf Neumann  
+
+
+	removed duplicate line
+
+2009-07-07  Gustaf A. Neumann  
+
+
+	- based introspection for procs/instprocs on new argument definition
+	  structures
+	 - allowing type checkers also for positional arguments
+	 (for now only, when nonpos args are given as well; we have
+	 to think about using these either for all procs/instprocs,
+	 or only, when e.g. type checkers are used; we have to
+	 make more benchmarking to get a better foundation)
+	 - registered the following type checkers for procs/instprocs:
+	 switch, integer, boolean, object, class
+	 Example
+	 o proc bar {-enable:switch o:object c:class} {
+	 return "o=$o c=$c"
+	 }
+	 - generated interface for ::xotcl::configure; now 97 interfaces are
+	 generated; shortcoming for bool/int converter stubs: optional
+	 0-vaues are not recognized, so use tclobj for the time being
+	 - extended regression test
+
+2009-07-06  Gustaf A. Neumann  
+
+
+	 - parse non-pos-args for procs/instprocs into new argument
+	  definition structure
+	- using new parseObjv for calling procs and instproc when
+	  nonpos-args are used (invocation time went from 9.08ms to
+	  5.95ms)
+	- TODO: complete implementation for regression test, base
+	  introspection/copy etc. on new structures
+
+2009-07-05  Gustaf A. Neumann  
+
+
+	 - support for enumeration types in c-code generator
+	- use function pointer for type checker instead of strings
+	- generated interface for ::xotcl::methodproperty
+
+2009-07-04  Gustaf A. Neumann  
+
+
+	- ::xotcl::my generated
+
+
+	- generated interface for ::xotcl::relation
+
+
+	 - support for generating interface for ::xotcl commands
+	- generated interface for ::xotcl::alias
+
+
+	- removed compatibility for versions before Tcl 8.4 (was not tested
+	  anyhow) This version requires at least Tcl 8.4.
+
+2009-07-01  Gustaf A. Neumann  
+
+
+	- separated C-code generator from declarations
+
+2009-07-01  Gustaf Neumann  
+
+
+	 - moved all definitions of method commands to generated code
+	- from 15356 generic/xotcl.c => 13408
+
+2009-06-30  Gustaf Neumann  
+
+
+	- all object methods generated
+	- added reference counting for patternobj
+	- some cleanup and reordering
+
+2009-06-30  Gustaf A. Neumann  
+
+
+	- committing snapshot
+
+2009-06-29  Gustaf Neumann  
+
+
+	- fixed regression test
+
+
+	- improved varargs handler, instforward
+
+2009-06-29  Gustaf A. Neumann  
+
+
+	 - !!! removed obsolete features
+	  * ability to specify nonpos args and pos args as different
+	  arguments
+	  * compile flags AUTOVARS, REFCOUNTED, REFCOUNT_TRACE
+	- added -flags with one argument + type
+	- generated all class methods from interface descriptions
+	- transtional version, not all test of regression test work correctly
+
+
+	- 3 class methods generated, handling args/allargs
+
+2009-06-28  Gustaf A. Neumann  
+
+
+	- added check methods
+
+
+	- all " info" commands generated
+
+
+	 - changed " info hasNamespace" to " info
+	  hasnamespace" (all commands and info options are lowercase
+	  only, no underscore)
+	- 11 " info" commands generated
+
+
+	- objv-stubs for all 23 class info methods
+
+2009-06-28  Gustaf Neumann  
+
+
+	- defined 5 more info methods view generator
+	- simplified objpattern handling
+
+2009-06-28  Gustaf A. Neumann  
+
+
+	- improved changelog entry
+
+
+	- added c-stub generate (generates Tcl_ObjCmdProc from method
+	  definitions in Tcl)
+
+2009-06-27  Gustaf A. Neumann  
+
+
+	- added generator for tclAPI.h
+	- defined 8 info methods based on the new objv parseing
+	  infrastructure
+	- replaced occurances of "instdestroy" by "dealloc" in documentation
+
+2009-06-27  Gustaf Neumann  
+
+
+	- committing snapshot
+	- changed method name "instdestroy" into "dealloc"
+	- new file: tclAPI.h
+
+2009-06-26  Gustaf A. Neumann  
+
+
+	- implemented yet another objv parser
+	- used currently only for XOTclClassInfoInstancesMethod()
+
+2009-06-25  Gustaf A. Neumann  
+
+
+	- new command: ::xotcl::createobjectsystem  
+	This command creates a basic object system with the specified
+	 as most general root class and the specified metaclass as
+	most general meta class.
+	 Example: ::xotcl::createobjectsystem ::oo::object ::oo::class
+	 In general, it would be possible to remove an objects system
+	 at runtime, but there is so far no tcl interface for this.
+	- extended framework to work with multiple root classes
+	- the basic root class of XOTcl is now ::xotcl::Object again
+	 (instead of ::oo::object) as before. The old setup can be
+	 achieved on the Tcl-layer.
+
+2009-06-25  Gustaf Neumann  
+
+
+	- added metaclass property for root metaclass
+	- metaclass property is set via ::xotcl::relation ... metaclass
+
+2009-06-23  Gustaf A. Neumann  
+
+
+	- new parse() infrastructure for factoring out common parsing
+	  patterns of objv[] parsers
+	- new error message handler: XOTclObjErrArgCntObj()
+	- shortend code by about 1000 lines (about 100 due to parse())

+
+
+	- fixed bug in "info precedence -intrinsic"
+
+
+	 - define default meta-class for ::xotcl::Class
+	- use default meta-class, when a the topmost meta-class of an
+	  object system is deleted
+	- fix regression test
+
+
+	- work on collateral damage after merge
+	- fixed many test cases from the regression thest
+	- wrote some changes to ChangeLog as a reminder
+
+
+	- new regression test file
+
+
+	 merge with 1.6.3 (HEAD)
+
+2009-06-19  Gustaf Neumann  
+
+
+	- follow Tcl's naming conventions more closely
+
+2009-06-14  Gustaf A. Neumann  
+
+
+	- updated Changelog
+
+
+	- fixed potential access to deleted command list item in
+	  FilterSearchAgain()
+	- fixed potential access deleted xotcl object by switching order
+	  in a condition

+
+
+	updated changelog, wrote announcement
+
+
+	- removed references to 1.6.2
+
+2009-03-04  Gustaf Neumann  
+
+
+	- re-enable small optimization
+
+
+	- factor out common code
+
+
+	- provide compatibility with Tcl 8.4
+
+2009-03-04  Gustaf A. Neumann  
+
+
+	- bump version number to 1.6.3
+
+
+	- simplify semantics of MixinSeekCurrent and FilterSeekCurrent,
+	  improve speed
+	- remove necessity to have tclCompile.h
+	- improve documentation
+
+2009-03-02  Gustaf A. Neumann  
+
+
+	some small performance improvements (use CreateHashEntry instead of
+	FindHashEntry, remove unneded argument, improve order of long and
+	expressions)
+
+
+	- some code cleanup
+	- new methods, when compiled with tcl 8.5; + MakeProcError (producing
+	error messages from xotcl methods) + PushProcCallFrame (compile
+	method to byte-code) The new support allows to call code at the begin
+	of a proc without using the old approach based on :xotcl::initProcNS
+
+2009-02-19  Gustaf A. Neumann  
+
+
+	- add comments to var resolution tests for objects without namespaces
+
+
+	- fixed reference counting
+	- removed temporary hacks
+	- added CONST to several functions
+	- added relative namespace handling
+
+2009-02-18  Gustaf A. Neumann  
+
+
+	- added Stefan's work for namespace resolvers
+	- fixed a memory leak for "obj exists" due to the changes
+	- found another memory leak, when e.g. "::info" is added as an alias
+	  and "info exists" is tested against non-existing vars
+
+2009-01-19  Gustaf A. Neumann  
+
+
+	- Correct deletion of user-metaclasses
+	- commenting existing and potential usage of namespace resolvers
+
+2008-12-01  Gustaf A. Neumann  
+
+
+	- Correct deletion of user-metaclasses: Deletion of
+	  user-metaclasses could lead to undestroyable objects, since the
+	  instances of the user-metaclasses were reclassed to
+	  ::xotcl::Object instead of ::xotcl::Class.
+	- extend regression test for such situations
+
+2008-11-03  Gustaf A. Neumann  
+
+
+	- remove CVS-based date line from documentation
+
+
+	- minor documentation updates

+	- some cleanup
+
+2008-10-17  Gustaf Neumann  
+
+
+	- handle nonposargs in method "copy" properly

+	- upgrading and downgrading can be performed via create (but
+	  using destroy/create instead of recreate)
+	- fixed bug, where an "o info precedence" could core, after a
+	  class C was destroyed, where class C was used as a superclass
+	  of a mixin of o.
+	- minor refactoring
+
+
+	extended regression test
+
+
+	fix close of TT
+
+2008-09-10  Gustaf A. Neumann

+
+	first part of fix when a class is "casted" (via method "class") into an
+	object
+
+2008-06-24  Gustaf A. Neumann  
+
+
+	added release statement to Changelog
+
+
+	added annouce files for 1.6.1
+
+2008-06-23  Gustaf A. Neumann  
+
+
+	   * additional argument for "info precedence": "-intrinsic"
+	  Syntax:  info precedence ?-intrinsic? ?pattern? If
+	  "-intrinsic" is specified, only the classes of the superclass
+	  type hierarchy are returnd. Otherwise, the precedence contains
+	  mixin classes as well.
+	  * Remove pattern argument from "info class"
+	  * Check results for guards to be boolean instead of integer (now,
+	  guards are allowed to return e.g. "true")
+	  * Bump version number to 1.6.1
+
+2008-06-04  Gustaf Neumann  
+
+
+	  * check in guards for boolean values, not for integer values, such
+	  that a guard {true} means success
+
+2008-05-30  Gustaf A. Neumann  
+
+
+	   * updating language reference
+	   * Fix contents for %proc in forwarders in cases,
+	 where the forwarder was called via next and
+	 the argument list for next was provided.
+	 Previously, "next" was used for %proc.
+
+2008-05-28  Gustaf Neumann  
+
+
+	   * make "info (inst)?forward -definition name" more robust
+	  (provide an error message, if  is nog given
+	  * New info subcommands "info parametercmd" and "info
+	  instparametercmd"
+	  * export *parametercmds in Serializer, use "-noinit" on slots as well
+
+2008-05-26  Gustaf Neumann  
+
+
+	- fixed bug in info instdefault, when argument is an empty string.
+
+2008-05-09  Gustaf A. Neumann

+2008-02-21  Gustaf A. Neumann  
+
+
+	- improved formatting and wording in Changelog entry
+
+
+	  * replaced Tcl_ObjSetVar2() with Tcl_SetVar2Ex() in nonposargs, since

+	referenced directly from from Tcl,
+
+2008-02-08  Martin Matuska  
+
+
+	- new info option for "info instmixin" supporting -guards and
+	  -closure support
+	- extended test cases for "info instmixin"
+
+2008-02-06  Gustaf A. Neumann  
+
+
+	   * Continued with info orthogonality change
+	  info mixin ?pattern?
+	  info instmixin ?pattern?
+	 ?pattern? behaves exactly like in the change of two days
+	 ago. Preceding colons in the name of the queried class are not
+	 required.
+	 Still to do "-closure" in
+	  info instmixin -closure ?pattern?
+	   * In all mentioned calls, where pattern refers to an object/class
+	 and it contains wild-cards, a preceding :: is added automatically
+	 to the search pattern, if it is missing. Since all object names
+	 start with ::, an omitted leading :: in a search pattern is an
+	 obvious mistake
+	   * Made the behavior "pattern" in the following calls identical
+	 concerning wild cards and object lookups
+	  mixin delete pattern
+	  instmixin delete pattern
+	  superclass delete pattern
+	   * extended regresson test
+
+2008-02-05  Gustaf A. Neumann  
+
+
+	 - fix getAllClassMixinsOf to handle combinations of transitive
+	  per class mixins and inheriting per-class mixin via the class
+	  hierarchy, removed getAllSubClasses
+	- extend test cases

+2008-02-04  Gustaf A. Neumann  
+
+
+	  * Potential incompatibility: provide a uniform interface to the
+	  following info subcommands
+	  info superclass ?-closure? ?pattern?
+	  info subclass ?-closure? ?pattern?
+	  info instances ?-closure? ?pattern?
+	  info instmixinof ?-closure? ?pattern?
+	  info mixinof ?pattern?
+	 In cases, where the option "-closure" is defined,
+	 the values are computed transitively.
+	 In cases, where a pattern is specified, and
+	 the pattern contains meta-characters, a list
+	 of results is returned matching the pattern
+	 (like "string match"). When no matching value
+	 is found, an empty list is returned.
+	 In cases, where a pattern is specified, and
+	 the pattern contains no meta-characters,
+	 a single value is returned korrespinding to
+	 the specified value. The pattern is used
+	 to lookup an object or class, such it is
+	 not necessary to provide fully qualified names).
+	 if there is no match, empty is returned.
+	 Previously, "info superclass" and "info subclass"
+	 returned a boolean value and performed
+	 always a transitive search. Returning ""
+	 is more consistent and more in line with Tcl.
+	 By using the option "-closure" one can
+	 perform the lookup in the transitive
+	 or in the intransitive sets.
+	 Still to do:
+	 children
+	 parent
+	 classchildren
+	 classparent
