+=head1 NAME
+
+Net::DummyInetd - A dummy Inetd server
+
+=head1 SYNOPSIS
+
+    use Net::DummyInetd;
+    use Net::SMTP;
+    
+    $inetd = new Net::DummyInetd qw(/usr/lib/sendmail -ba -bs);
+    
+    $smtp  = Net::SMTP->new('localhost', Port => $inetd->port);
+
+=head1 DESCRIPTION
+
+C<Net::DummyInetd> is just what it's name says, it is a dummy inetd server.
+Creation of a C<Net::DummyInetd> will cause a child process to be spawned off
+which will listen to a socket. When a connection arrives on this socket
+the specified command is fork'd and exec'd with STDIN and STDOUT file
+descriptors duplicated to the new socket.
+
+This package was added as an example of how to use C<Net::SMTP> to connect
+to a C<sendmail> process, which is not the default, via SIDIN and STDOUT.
+A C<Net::Inetd> package will be available in the next release of C<libnet>
+
+=head1 CONSTRUCTOR
+
+=over 4
+
+=item new ( CMD )
+
+Creates a new object and spawns a child process which listens to a socket.
+C<CMD> is a list, which will be passed to C<exec> when a new process needs
+to be created.
