+=head1 SYNOPSIS
+
+    test-server [socket|[address:]port|-]
+
+=head1 DESCRIPTION
+
+This command starts a test server simulating a Quancom USB-OPTO device.
+It's use is for testing purpose only (testing the Quancom.pm module).
+
+=head1 INVOCATION
+
+On invocation you may pass a parameter:
+
+=over
+
+=item I<socket>
+
+This should be the name of a socket file. The socket file must not
+exist, it will be created. The name has contain at least on slash ("/")
+to be distinguished from a port number.
+
+=item [I<address:>]I<port>
+
+Using this the server will bind to the specified port on 0.0.0.0 or the 
+address supplied.
+
+=item B<->
+
+Using a single "-" the server will communicate over STDIN/STDOUT. Some
+changes in behaviour are implicit set. See L<Quancom::Test::Server> for
+more details. This option is for testing the test server.
+
+=item B<no parameter at all>
+
+If you do not pass anything, the server creates a temporary socket file.
+
+=back
+
+In all cases, the server tells you on STDERR about the "channel" used
+for communication.
