A Perl-regex based copy script, derived from the rename script

	I really like the regex syntax of the rename perl script, e.g.:

	copy "s/OldFile/NewFile/" OldFile*

	So here it is!

	Dump of LZW rendering engine for TIC by Deck.

	It always makes me nervous when I see code snippets in dropbox --
	the link can disappear anytime. So I encoded the dropbox ZIP into a
