doxygen

Documentation system for C, C++, and other languages

Doxygen is a documentation system for C++, C, Java, Objective-C, Python, IDL (Corba and Microsoft flavors) and to some extent PHP, C#, and D. It can generate an on-line class browser (in HTML) and/or an off-line reference manual (in LaTeX/PostScript/PDF) from a set of documented source files. The documentation is extracted directly from the sources.
