+=head1 NAME
+
+Net::SNPP - Simple Network Pager Protocol Client
+
+=head1 SYNOPSIS
+
+    use Net::SNPP;
+    
+    # Constructors
+    $snpp = Net::SNPP->new('snpphost');
+    $snpp = Net::SNPP->new('snpphost', Timeout => 60);
+
+=head1 NOTE
+
+This module is not complete, yet !
+
+=head1 DESCRIPTION
+
+This module implements a client interface to the SNPP protocol, enabling
+a perl5 application to talk to SNPP servers. This documentation assumes
+that you are familiar with the SNPP protocol described in RFC1861.
+
+A new Net::SNPP object must be created with the I<new> method. Once
+this has been done, all SNPP commands are accessed through this object.
+
+=head1 EXAMPLES
+
+This example will send a pager message in one hour saying "Your lunch is ready"
+
+    #!/usr/local/bin/perl -w
+    
+    use Net::SNPP;
+    
+    $snpp = Net::SNPP->new('snpphost');
+    
+    $snpp->send( Pager   => $some_pager_number,
+	         Message => "Your lunch is ready",
+	         Alert   => 1,
+	         Hold    => time + 3600, # lunch ready in 1 hour :-)
+	       ) || die $snpp->message;
+    
+    $snpp->quit;
+
+=head1 CONSTRUCTOR
+
+=over 4
+
+=item new ( [ HOST, ] [ OPTIONS ] )
+
+This is the constructor for a new Net::SNPP object. C<HOST> is the
+name of the remote host to which a SNPP connection is required.
+
+If C<HOST> is not given, then the C<SNPP_Host> specified in C<Net::Config>
+will be used.
+
+C<OPTIONS> are passed in a hash like fashion, using key and value pairs.
+Possible options are:
+
+B<Timeout> - Maximum time, in seconds, to wait for a response from the
+SNPP server (default: 120)
+
+B<Debug> - Enable debugging information
+
+
+Example:
+
+
+    $snpp = Net::SNPP->new('snpphost',
+			   Debug => 1,
+			  );
+
+=head1 METHODS
+
+Unless otherwise stated all methods return either a I<true> or I<false>
+value, with I<true> meaning that the operation was a success. When a method
+states that it returns a value, failure will be returned as I<undef> or an
+empty list.
+
+=over 4
+
+=item reset ()
+
+=item help ()
+
+Request help text from the server. Returns the text or undef upon failure
+
+=item quit ()
+
+Send the QUIT command to the remote SNPP server and close the socket connection.
+
+=back
+
+=head1 EXPORTS
+
+C<Net::SNPP> exports all that C<Net::CMD> exports, plus three more subroutines
+that can bu used to compare against the result of C<status>. These are :-
+C<CMD_2WAYERROR>, C<CMD_2WAYOK>, and C<CMD_2WAYQUEUED>.
