24 /* \summary: AFS RX printer */
25
26 /*
27 * This code unmangles RX packets. RX is the mutant form of RPC that AFS
28 * uses to communicate between clients and servers.
29 *
30 * In this code, I mainly concern myself with decoding the AFS calls, not
31 * with the guts of RX, per se.
32 *
33 * Bah. If I never look at rx_packet.h again, it will be too soon.
