Presumably one of the original staff who bulk-transferred mods there from other sources, since I didn't submit it back then. They probably didn't have time to actually check what all those hundreds of mods they uploaded were, and just put up some token description.
As far as I can see the above linked file should be the most recent version (if you can call something a year and a half old recent).
Be aware that the hack is incompatible with the USM mod "out of the box" since it was released earlier than USM, you'll need to do some manual merging if you want to use both. (I should probably make a new version of the hack which is a bit more compatible with other things...)
