# @BLURB: helper functions eclass for perl modules
# @DESCRIPTION:
# The perl-functions eclass is designed to allow easier installation of perl
# modules, and their incorporation into the Gentoo Linux system.
# It provides helper functions, no phases or variable manipulation in

# test is completely irrelevant to end users, and frequently fail simply
# because the authors of Test::Pod... changed their recommendations, and thus
# failures are only useful feedback to Authors, not users.
