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 implementation does not care about what kind of package it builds.

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.
