Dist::Requires is a Perl module that answers the question "Which
packages are required to install a distribution with a
particular version of perl?" The distribution can be in an
archive file or unpacked into a directory. By default, the
requirements will only include packages that are newer than the
ones in the perl core (if they were in the core at all). You can
turn this feature off to get all requirements. You can also
control which version of perl to consider. my $dr =
Dist::Requires->new(); # From a distribution archive file... my
$prereqs = $dr->prerequisites(dist => 'Foo-Bar-1.2.tar.gz'); #
From an unpacked distribution directory... my $prereqs =
$dr->prerequisites(dist => 'Foo-Bar-1.2');
