# @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
|
|
# global scope.
