My additions are:
This program is very useful for me. Up till now, I've made all my help files with this program. You can insert links, bitmaps etc. It has everything you need to make a Windows Help File. Of course some knowledge of the RTF format is required.
In Feb. 2002 the program got a face-lift. Also in addition to the MAP file generator, it makes also a "cont" (content) file. The extension can be changed to cnt and than edited with the Windows Help File Compiler. It will work without editing, but there might be some "beauty" problems.
Since January 20, 2002, this program has also a help file. In fact, it's so simple that you won't need one. But it is very good to have an example RTF file with this program.
