Generating documentation from Perl code (not just POD)

[aufflick]

What I'd like to do is be able to generate documentation of classes, methods, inheritence etc. from Perl code itself (either via parsing or introspection - both have their downfalls).

Ideally a script/module would do that, and also interleave the POD from the file, so any POD directly before the method/sub would be linked to it. Any method/sub without POD would at least be documented by it's name.

Of course a major limitation is that (for OO Perl at least), we have no idea what the method arguments are, simply from robotically inspecting the code. Something I always liked in OpenACS is the way that they replace the builtin Tcl proc keyword with a custom ad_proc keyword that works just the same as proc but which takes an optional documentation block that accepts javadoc-like keyword embedding and also a block detailing any arguments and their default values. Because of the tight coupling, the generated documentation is very rich for little developer effort.

Does anyone know of attempts at this sort of thing in Perl, or have any good ideas to offer? Ideally I want to come up with something that will work with existing Perl code, and that any extensions won't break normal Perl compilation (no literate programming preprocessors need apply).
