# $Log: quotasanitycheck,v $
# Revision 1.1  1998-09-17 07:30:12  hjp
# Made messages more user friendly (and less admin friendly).
# allow grace time "NOT STARTED".
# 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.
