Revision:	1.4
Committed:	Mon Jun 10 14:10:43 2002 UTC (22 years, 3 months ago) by tdb
Branch:	MAIN
CVS Tags:	HEAD
Changes since 1.3:	+2 -2 lines
State:	*FILE REMOVED*
Log Message:	Tidy up of files. These are all old things that are not only no longer used but are also probably useless to anyone other than us. This saves checking them out all the time, and makes the "cms/source" tree contain only current stuff. They'll still exist in the attic's though :)
