/*
* print PPP statistics:
- * pppstats [-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.
+ * pppstats [-a|-d] [-v|-r|-z] [-c count] [-w wait] [interface]
*
+ * -a Show absolute values rather than deltas
+ * -d Show data rate (kB/s) rather than bytes
+ * -v Show more stats for VJ TCP header compression
+ * -r Show compression ratio
+ * -z Show compression statistics instead of default display
*
* History:
* perkins@cps.msu.edu: Added compression statistics and alternate
* display. 11/94
