/*
* QUOTA An implementation of the diskquota system for the LINUX operating
* system. QUOTA is implemented using the BSD systemcall interface
* as the means of communication with the user level. Should work for
* all filesystems because of integration into the VFS layer of the
* operating system. This is based on the Melbourne quota system wich
* uses both user and group quota files.
*
* Program to query for the internal statistics.
*
* Author: Marco van Wieringen <mvw@planets.elm.net>
