Description:

Doxygen is a documentation system for C, C++ and IDL. It can generate an
on-line class browser (in HTML) and/or an off-line reference manual (in LaTeX)
from a set of documented source files. There is also support for generating man
lpages and for converting the generated output into Postscript, hyperlinked PDF
or compressed HTML. The documentation is extracted directly from the sources.

Doxygen can also be configured to extract the code-structure from undocumented
source files. This can be very useful to quickly find your way in large source
distributions.
