I wrote a filter for doxygen so it could be used on perl code with suitable comments.

See http://smop.org/computing/perl/doxygen.html

It really helps if you know C++ when using it, because the comments you have to place in front of your code are basically a translation from perl to C++ function prototypes.

Take a look at the generated demo docs, at the source perl code and decide whether it's sufficiently "better" for you than POD.

For most perl code, I think POD wins, but DoxyGen::Filter could be useful if you program in a heavy OO, java-like style.
