I wondered about that.  I didn't see git.  Sorry, and yes, that is good.

Yes, but as has been discussed already by now, we're not sure if those
features are actually supported, and some seem to be sure they are not. 
The confusion comes in because the Microsoft XP MX330-packaged scanning
software does do autodetect of a sort (when you specify "picture", it
takes all picture-looking things and makes a seperate cropped file for
each, and does a pretty darn good job of it without cutting too much or
too little), so presumably that's software driven by the program in the
computer, not in the scanner/multifunction device.

No, apparently the documentation was more outdated than git, so we're good
once that's done.  If I had known this existed back in the summer, I would
have had many more months of not having to run VMWARE with XP in it,
crashing my computer so much ...
