What was the reason to develop doxygen?
I once wrote a GUI widget based on the Qt library (it is still available at http://qdbttabular.sourceforge.net/ and maintained by Sven Meyer). Qt had nicely generated documentation (using an internal tool which they didn’t want to release) and I wrote similar docs by hand. This was a nightmare to maintain, so I wanted a similar tool. I looked at Doc++ but that just wasn’t good enough (it didn’t support signals and slots and did not have the Qt look and feel I had grown to like), so I started to write my own tool…
