What's GNU: Texinfo
Texinfo provides a clean input language with everything necessary for producing handsome printed documentation and highly usable on-line hypertext help. The info viewer provides a friendly interface for reading the on-line Info files.
The nicest thing I have found about Texinfo is that you don't need to know TeX to use it. I have been happily writing in Texinfo for around seven years, and have not really needed to learn TeX. Even though Texinfo has over 160 commands, what I've covered in this article is 95% of what most people would use on a day-to-day basis.
I also recommend buying and reading the Texinfo manual from the FSF. It is well-written and thorough. You will need to do this anyway if you plan to write a large Texinfo file, as this article has just scratched the surface. The Texinfo manual comes with the Texinfo distribution, and is of course written in Texinfo; this provides a nice example that uses all of Texinfo's features.
Thanks to Miriam Robbins for making me clarify a number of points in this article, and to Robert J. Chassell of the FSF (primary author of the Texinfo manual) for his comments.
