Right, sorry for the long wait, here is the first version.
To run it you will need the following:
* A UNIX compatible command line diff utility (on windows I use the one that comes with MinGW)
* Python 2.4 installed
Extract the three python files and run the one called diffbb.py, it should print out some usage instructions about the arguments it takes.
I haven't had a lot of time to test this thing all that rigorously, although it seems to at least create correct MOD files even if the choice of find targets and such is still a bit brainless.
Please take a copy and test it to destruction. I'll do some more work in the future to trim down the inline find strings and pick better targets to ensure higher compatibility with other mods.
If you have any trouble with the script then I'll try and help, but I can't really help with things like installing a diff utility etc...
