( #3333=superdoc: print w/replies, xml ) Need Help??

You already have all the pieces that you need:

  1. In your root node you show how you get the command line arguments.
  2. bart showed you how to
    1. get the pathname of the project.txt file using File::Basename,
    2. parse the value out of the REVISION_LOCATION: line, and
    3. turn that filename from relative to absolute using File::Spec's rel2abs, using the pathname of project.txt as the base.

If you're unsure on how to open the project.txt file instead of using the magic while(<>) that bart used, please see "Files and I/O" in perlintro.

Updated wording slightly.
