/* \summary: AFS RX printer */
/*
* This code unmangles RX packets. RX is the mutant form of RPC that AFS
* uses to communicate between clients and servers.
*
* In this code, I mainly concern myself with decoding the AFS calls, not
* with the guts of RX, per se.
*
* Bah. If I never look at rx_packet.h again, it will be too soon.
*
* Ken Hornstein <kenh@cmf.nrl.navy.mil>
