Not really "hip OO lingo", it's just the name of one of the patterns written
up in the "Gang of Four" (GoF) book on design patterns (copyright in my
edition is 1995). All of Matthew's postings have been dealing with
implementation of these design patterns into Ada95 (the book contains examples
in C++).

Design Patterns by Erich Gamma, Richard Helm, Ralph Johnson and John
Vlissides.

"Factory Method
Intent:
Define an interface for creating an object, but let all subclasses decide
which class to instantiate. Factory Method lets a class defer instantiation to
subclasses."

Hope this helps :-)
