.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module mediates between some version that perl sees in a package
and the version that is published by the CPAN indexer.
.PP
It's only written as a helper module for both CPAN.pm and CPANPLUS.pm.
.PP
As it stands it predates version.pm but has the same goal: make
version strings visible and comparable.
