-// Wed 27 Apr 2005 - Brain
-// I've taken our our old wildcard routine -
-// although comprehensive, it was topheavy and very
-// slow, and ate masses of cpu when doing lots of
-// comparisons. This is the 'de-facto' routine used
-// by many, nobody really knows who wrote it first
-// or what license its under, i've seen examples of it
-// (unattributed to any author) all over the 'net.
-// For now, we'll just consider this public domain.
