-Disclaimer: 
-===========
-
-This software is provided as is. I take no responsibility if it destroys your
-data or opens up a security hole on your firewall. That said, I have yet to
-hear something about this happening.
-
-I did not create this code myself, most was written by Tom Marshall, later on
-Harald Welte and then Steven van Acker ported it to the new 2.6 netfilter API.
-I just picked up this code in 2007 and made it compile and hopefully work with
-the new changed netfilter API.
-
-Bugs: 
-=====
-
-Of course there are. One of the most important ones, is that you MUST NOT
-filter outgoing connections otherwise the reply packes go missing. I tried to
-figure out, why the _expect call is not taking care of the outgoing connections
-but I was not able to figure this out. I gladly welcome patches that fix this
-and other bugs.
-
-Build Instructions: 
-===================
-
-Have the kernel source ready in some place and NF_CONNTRACK_NAT enabled in the
-configuration otherwise you will get an error during make. The Kbuild setup
-looks in /lib/modules/\`uname -r\`/build for the source. 
-
-If the source is located in another place set the KERNELDIR environment
-variable accordingly.
-
-After that a:
-
-	* make 
-	* make modules_install (as root)
-
-should be enough.  
-Then do a "modprobe nf_nat_rtsp" as root and try to connect to a RTSP
-service.
