+.Sh NAME
+.Nm portmap
+.Nd
+.Tn DARPA
+port to
+.Tn RPC
+program number mapper
+.Sh SYNOPSIS
+.Nm portmap
+.Op Fl d
+.Sh DESCRIPTION
+.Nm Portmap
+is a server that converts
+.Tn RPC
+program numbers into
+.Tn DARPA
+protocol port numbers.
+It must be running in order to make
+.Tn RPC
+calls.
+.Pp
+When an
+.Tn RPC
+server is started, it will tell
+.Nm portmap
+what port number it is listening to, and what
+.Tn RPC
+program numbers it is prepared to serve.
+When a client wishes to make an
+.Tn RPC
+call to a given program number,
+it will first contact
+.Nm portmap
+on the server machine to determine
+the port number where
+.Tn RPC
+packets should be sent.
+.Pp
+.Nm Portmap
+must be started before any
+.Tn RPC
+servers are invoked.
+.Pp
+Normally
+.Nm portmap
+forks and dissociates itself from the terminal
+like any other daemon.
+.Nm Portmap
+then logs errors using
+.Xr syslog 3 .
+.Pp
+Option available:
+.Bl -tag -width Ds
+.It Fl d
+(debug) prevents
+.Nm portmap
+from running as a daemon,
+and causes errors and debugging information
+to be printed to the standard error output.
