libclass-factory-perl - 1.06-5 main

This is a simple module that factory classes can use to generate new
types of objects on the fly, providing a consistent interface to common
groups of objects.
.
Factory classes are used when you have different implementations for
the same set of tasks but may not know in advance what implementations
you will be using. With a factory class this is easy. Class::Factory
even provides a simple constructor for you.
