Fribidi uses c2man to generate its manpage, but c2man is pretty dead. Debian removed it from their distro in around 2005. Ubuntu had it on life-support until 2011, but with a large warning to avoid using it due to upstream dead/abandoned and better modern solutions. Both distros recommend doxygen as an alternative. Therefore, this is a request to switch fribidi to using some other documentation system. Requiring an obsolete and not-widely/directly-available to (re)generate the manpage makes it more difficult to hack/port fribidi.
Right... FWIW I have a fork of c2man that I use to generate fribidi's docs:
This was all written back in 2005... I don't have time or motivation to change it now since the library itself has not changed in almost a decade.
For your info, I know it's an old bug, but I'm working on it. I've created a branch named Doxygen at https://github.com/Oxalin/fribidi/tree/doxygen
Building fribidi build the new doc, but I still want to tune it a bit before proposing a merge.
Please open an issue or Pull-Request on github soon so others are also aware of your work. Thanks.
