I'm pleased to report that Crw (and the Java front-end JCrw) works significantly better than Canon's Mac software. They're still not as good as the official Canon software on the PC, which lets you click on an image and say "this is white", and preview the result, but they're light-years ahead of the garbage Canon software.

Now, it wouldn't be all that hard to hack all of this up, given all the pieces that are here. Hmm...
