DESCRIPTION

This module mediates between some version that perl sees in a package and the version that is published by the CPAN indexer.

It's only written as a helper module for both CPAN.pm and CPANPLUS.pm.

As it stands it predates version.pm but has the same goal: make version strings visible and comparable.
