A List of Differences Between Versions?

It's probably available somewhere (I didn't notice it on the IMDb) but I wanted to know if someone could supply a list of the differences between versions. The reason being is I have a version that says it's the unrated directors cut, but it's honestly hard to tell. The beginning of the film, The whole home for the blind explosion and the Toxie massacre that ensues seems to be much gorier than I remembered it being. But aside from that, the rest of the film is rather mild. Just wondering if anyone can supply a list. Thanks!
