+> Make cleanup routine delete <tmpfile>.$$ also.
+> When debugging, write a (one line) shell script to remove temporary
	files after investigation and tell the user about it.
+> Use more variables to specify location of remote logfiles. This should
	make it easier to use other servers/repositories.
+> Use xargs to invoke cvs, instead of using shell while loops. It looks
	cleaner and is probably more efficient.
+> Misc. small fixes, cleanup, and error checking.
