169 .IX Header "DESCRIPTION"
170 This module mediates between some version that perl sees in a package
171 and the version that is published by the \s-1CPAN\s0 indexer.
173 It's only written as a helper module for both \s-1CPAN\s0.pm and \s-1CPANPLUS\s0.pm.
175 As it stands it predates version.pm but has the same goal: make
176 version strings visible and comparable.
179 This program is free software; you can redistribute it and/or
