- nx.tcl: don't use mixins in method "contains", but remap the new implementation. If there are ten thousands of classes defined, adding mixins to the root meta-class degrades linearly on the number of classes defined (the mixin paths for all classes must be invalidated). This might be a problem for frequent "contains" invocations. - bup version numbers for nx, xotcl2 and nsf to 2.0b2
- 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.
