- 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 accordingly. - Discriminate between parsing simple and complex part entities. In the simple case, multi-line part sections are not allowed anymore. - Adopted the recent changes in the object introspection interfaces
