+ * Copyright (C) 1984, Sun Microsystems, Inc.
+ *
+ * The following procedures are supported by the protocol:
+ *
+ * PMAPPROC_NULL() returns ()
+ *	takes nothing, returns nothing
+ *
+ * PMAPPROC_SET(struct pmap) returns (bool_t)
+ *	TRUE is success, FALSE is failure.  Registers the tuple
+ *	[prog, vers, prot, port].
+ *
+ * PMAPPROC_UNSET(struct pmap) returns (bool_t)
+ *	TRUE is success, FALSE is failure.  Un-registers pair
+ *	[prog, vers].  prot and port are ignored.
+ *
+ * PMAPPROC_GETPORT(struct pmap) returns (long unsigned).
+ *	0 is failure.  Otherwise returns the port number where the pair
+ *	[prog, vers] is registered.  It may lie!
+ *
+ * PMAPPROC_DUMP() RETURNS (struct pmaplist *)
+ *
+ * PMAPPROC_CALLIT(unsigned, unsigned, unsigned, string<>)
+ *	RETURNS (port, string<>);
+ * usage: encapsulatedresults = PMAPPROC_CALLIT(prog, vers, proc, encapsulatedargs);
+ *	Calls the procedure on the local machine.  If it is not registered,
+ *	this procedure is quite; ie it does not return error information!!!
+ *	This procedure only is supported on rpc/udp and calls via
+ *	rpc/udp.  This routine only passes null authentication parameters.
+ *	This file has no interface to xdr routines for PMAPPROC_CALLIT.
+ *
+ * The service supports remote procedure calls on udp/ip or tcp/ip socket 111.
