Detailed Description

template<class T, class Arg>
class PreFactory< T, Arg >

Implements a template for the "PreFactory" pattern.

The "factory" pattern is a technique for creating new instances of objects which defines an abstract interface, (represented by the "Make" module). The subclasses of factory decide which class to instantiate.

Each subclass of factory "registers" itself at compile time; therefore, the addition of a new factory requires no change the parent class.
