Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I've inherited some perl code that traverses several source code files with very little documentation. I was hoping that there might be a tool that would reverse engineer the code and would create a flow diagram of the system. Anyone heard of such a beast? Any recommendations short of walking through the code line by line? The code doesn't currently work and they want me to get it working.
