I realize that Project Management and Version Control are different, but I have found Rcs.pm to be invaluable for automating the transfer of project files to or from an RCS version control system.

In addition, Rcs.pm is the only software I was able to find anywhere for scripting the RCS system.

When I used this software, I saved my company hours of manually moving files. That was last year, and since then I have been sold on Perl, because it has so many useful (and free) modules that are not found anywhere else.
