3)   A very similar program I wrote a while back, {Ice}<Koomen>Lisp>COPYDIR, also had an option that would delete all files in the destination directory that matched the source filespec (minus directory, ofcourse) but that were not (or no longer) in the source. For instance, as a result of repeated Brownie''ing {Phylum/Eris}<Lisp>Current> into {Ice}<Lisp>Current> over time a lot of files in the latter directory are now obsolete. '
'
I propose the option PURGE as follows':'
	(COPYFILES	''{Eris}<Lisp>Current>'
				''{Ice}<Lisp>Current>'
				''(>A PURGE))'
'
updates the destination dir from the source dir with all obsolete files purged.'
