What tools exist for analyzing a Perl based system? I've been handed a CD with a Perl/CGI system on it and I'm supposed to report back on its quality/maintainability. I've run it through perltidy so it now conforms to the "one true Perl style" and is legible. It's 37 .pl files, 10K+ lines and a couple of comments.
What other tools exist for analyzing a Perl program? In other languages I have used programs that produce:
- System summaries (lines of code, file statistics...)
- Variable cross-reference
- Tree structure of the system
I've checked google, google groups, cpan, perl.com and here with no luck. Am I just using the wrong search terms?
