Description:

This module allows you to build packages that return different variations
depending on what parameters are given.

Users of your package will receive a subroutine able to take parameters and
return the name of a suitable variant package. The implmenetation does not
care about what kind of package it builds.

Declaring a variable package
There are two important parts to creating a variable package. You first
have to give 'Package::Variant' some basic information about what kind
of package you want to provide, and how. The second part is
implementing a method receiving the user's arguments and generating
your variants.
