UnRarX 2.2 is utility for Mac OS X to unpack files stored in the Rar archive format. I don't use Rar. If you do and have tried UnRarX, please let us know here how it works for you.

The UnRarX website says that source code will be released on SourceForge. However, there isn't any source code on there. So, although UnRarX lists its license as GPL, I'm going to call it Freeware for now.
