Devel::Loaded - Post-execution dump of loaded modules

    perl -MDevel::Loaded programname 2>/dev/null

The Devel::Loaded module installs an at-exit handler to generate a dump of all the module files used by a Perl program. If used in conjunction with a perl -c, you find those files loaded in at compile time with "use". If you are willing to wait until after the program runs, you can get them all.

This is compile-time only:

    $ perl -MDevel::Loaded perldoc 2>/dev/null
    /usr/local/devperl/lib/5.00554/Exporter.pm
    /usr/local/devperl/lib/5.00554/strict.pm
    /usr/local/devperl/lib/5.00554/vars.pm
    /usr/local/devperl/lib/5.00554/i686-linux/Config.pm
    /usr/local/devperl/lib/5.00554/Getopt/Std.pm

This will also catch run-time loads:

    #!/usr/bin/perl
    use Devel::Loaded;
    ...

The plxload and the pmload programs, which use this technique.

Neil Bowers has written a review <http://neilb.org/reviews/dependencies.html> of Perl modules for getting dependency information (26 of them at the time of writing).
