+ * route        This file contains an implementation of the command
+ *              that manages the IP routing table in the kernel.
+ *
+ * Version:     route 1.94 (1997-09-21)
+ *
+ * Maintainer:	Bernd 'eckes' Eckenfels, <net-tools@lina.inka.de>
+ *
+ * Author:      Fred N. van Kempen, <waltje@uwalt.nl.mugnet.org>
+ *		(derived from FvK's 'route.c     1.70    01/04/94')
+ *
+ * Modifications:
+ *	 	Johannes Stille:	for Net-2Debugged by 
+ *					<johannes@titan.os.open.de>
+ *	 	Linus Torvalds:		Misc Changes
+ *	 	Alan Cox:		add the new mtu/window stuff
+ *	 	Miquel van Smoorenburg:	rt_add and rt_del
+ *	 {1.79}	Bernd Eckenfels:	route_info
+ *	 {1.80}	Bernd Eckenfels:	reject, metric, irtt, 1.2.x support.
+ *	 {1.81}	Bernd Eckenfels:	reject routes need a dummy device
+ *960127 {1.82} Bernd Eckenfels:	'mod' and 'dyn' 'reinstate' added
+ *960129 {1.83}	Bernd Eckenfels:	resolve and getsock now in lib/, 
+ *					REJECT displays '-' as gatway.
+ *960202 {1.84} Bernd Eckenfels:	net-features support added
+ *960203 {1.85} Bernd Eckenfels:	"#ifdef' in '#if' for net-features
+ *					-A  (aftrans) support, get_longopts
+ *960206 {1.86} Bernd Eckenfels:	route_init();
+ *960218 {1.87} Bernd Eckenfels:	netinet/in.h added
+ *960221 {1.88}	Bernd Eckenfels:	aftrans_dfl support
+ *960222 {1.90} Bernd Eckenfels:	moved all AF specific code to lib/.
+ *960413 {1.91} Bernd Eckenfels:	new RTACTION support+FLAG_CACHE/FIB
+ *960426 {1.92} Bernd Eckenfels:	FLAG_SYM/-N support
