I first made a texinfo file, and then translated it into a context file, and it turns out that the latter much simpler to create indexes and such: in the texinfo format, one has to keep track of them in various parts because of TeX's limited ability to do such things. In addition, GNU has policy of enforcing original TeX with limited Unicode support, making it suitable for simpler types of manuals only. There is no requirement to use this format or produce 'info' documentation, but it would be nice to produce an HTML. Personally, I prefer the PDF format.
