+/* \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.
