Dear Wise Monks,

I am trying to track the module dependencies for a large perl project (e.g. package ABC uses package DEF uses...). I was hoping to find or create an automatic tool to do this, similar to the "cdep" tool that John Lakos made in Large-Scale C++ Software Design.

I set up a miminal package, referring to another minimal package:

package ABC;
use DEF;
1;
[download]

I thought perhaps something like this would work:

perl -MO=Xref,-oreport ABC.pm
grep -w Package report | grep -v '(' | sort -u > dep_report
[download]

However, all I get is:

    Package attributes
    Package UNIVERSAL
[download]

Is there a better tool available to find the module "use" dependencies? Thanks for your help.
