# $Log: quotasanitycheck.pl,v $
# Revision 1.2  2005-12-12 08:48:59  hjp
# Allow non-word characters in usernames (machine accounts end with $)
#
# Revision 1.1  1998/09/17 08:32:57  hjp
# CVS cleanups:
# 	Added quotasanitycheck.pl and removed quotasanitycheck.
# 	Added quotasanitycheck
#
#
# check quotas for sanity:
#     *	for each user, the difference between current usage and hard
#	limit must be less than the available space (preferably much
#	less).
#     * all quotas must be above some limit
#     * soft quotas  must be less than hard quotas.
