libpackage-variant-perl - 1.003002-1.1 main

Package::Variant allows you to build a variable package that contains a
package template and can use it to build variant packages at runtime.
.
Your variable package will export a subroutine which will build a
variant package, combining its arguments with the template, and return
the name of the new variant package.
.
The implementation does not care about what kind of packages it builds,
be they simple function exporters, classes, singletons or something
entirely different.
