+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
+ *
+ *
+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
+ * released with almost no problems. 2.6.14-x was released
+ * with some important changes: nfcache was removed; After
+ * some weeks of trouble we figured out that some IMQ fields
+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
+ * These functions are correctly patched by this new patch version.
+ *
+ * Thanks for all who helped to figure out all the problems with
+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
+ * I didn't forget anybody). I apologize again for my lack of time.
+ *
+ * More info at: http://www.linuximq.net/ (Andre Correa)

+ This option adds a `ROUTE' target, which enables you to setup unusual
+ routes. For example, the ROUTE lets you route a received packet through
+ an interface or towards a host, even if the regular destination of the
+ packet is the router itself. The ROUTE target is also able to change the
+ incoming interface of a packet.
+
+ The target can be or not a final target. It has to be used inside the
+ mangle table.
+
+ If you want to compile it as a module, say M here and read
+ Documentation/modules.txt. The module will be called ipt_ROUTE.o.
+ If unsure, say `N'.
