devel/p5-Module-Dependency 1.86_2

Module::Dependency - Collection of modules for examining dependencies between parents and children, like Perl files

A set of pure-perl modules and helper programs that let you build a database of the dependency links between a collection of Perl files, and then query that database, even producing text, HTML, PostScript or graphical reports.

The database in question is actually a simple Storable image of a Perl data structure, and you can create as many of these as you want. You can use the command-line tools, or write your own Perl to query and manipulate the data however you want.
