The following shell scripts are:

	rm -- remove files to compressed storage in /usr/tmp/.$USER
	unrm -- bring those files back
	rml -- list files "removed"
	rmclean -- clean up /usr/tmp/.$USER

rm, unrm, and rml were originally created by blknowle@uokmax.UUCP (Brad Knowles)
and were modified by jeffm@uokmax.UUCP (Jeff Medcalf).  rmclean was created by
jeffm@uokmax.UUCP.


#! /bin/sh
#This is rm.  It moves files to be removed to /usr/tmp/.$USER, then compresses
#them.  If /usr/tmp/.$USER does not exist, it will be created.  The -f option
#forces removal to be permanent.

Is she spoiled?
No, she always smells that way.
