The gendiff script following my .sig is a standard part of rpm, but is
useful in other situations as well :-)
Basically, whenever you want to make a patch to a file, you save the
original with your special extension - i.e. I save the originals of files
I modify with a '.sopwith' extension ('cp filename.c filename.c.sopwith').
Then when you want to get The Patch for, say, /usr/src/linux, just run:
cd /usr/src
gendiff linux .sopwith > /tmp/mycoolkernel.patch
