* Uses the NFS style quota system/quotactl rather than the Melbourne
* quota system.
*
- * $Log$
- * Revision 1.5 1990-03-06 15:59:08 jnrees
- * x*.5 replaced with x/2;
- * x*1.2 with (x*6)/5;
- * This avoids linking in the floating-point library.
- *
- * Revision 1.4 90/01/27 19:48:05 jnrees
- * Grows quotas file if necessary
- * Allows setting quota for a range of uid's.
- *
- * Revision 1.3 88/10/06 10:46:08 raeburn
- * (mar) Don't expire timers on users currently over quota.
