Generation of wxHelp files

The program tex2help generates .xlp files from LaTeX documents; in particular, it is used on classes.tex from the wxWindows user manual and hyText user manual. The utility makes use of the library tex2any which handles parsing and traversal of LaTeX file structure, allowing the conversion utility to simply output appropriate block information and text to files. Unfortunately I do not have time to document these programs, but examination of the source should give an idea of what's going on.

The file wxhlpblk.h contains block type definitions used by wxHelp and may be included by generators to ensure blocks of the appropriate type are generated.
