/*
* print PPP statistics:
* ipppstats [-i interval] [-v] [-r] [-c] [interface]
*
* -i <update interval in seconds>
* -v Verbose mode for default display
* -r Show compression ratio in default display
* -c Show Compression statistics instead of default display
* -a Do not show relative values. Show absolute values at all times.
*
*
* History:
* perkins@cps.msu.edu: Added compression statistics and alternate
* display. 11/94
* Brad Parker (brad@cayman.com) 6/92
