The Tain

This has always a very useful little app, but now that it has a GUI interface, well I dont know how it could get any better.

OmniPatch does exactly as it advertises, creates and applies patch files. This may not seem like much, but when you are trying to get maps tested, well OmniPatch makes things that much easier for testers to update without massive downloads of the full files. Not to mention it works on other file types as well. :o)
