Syncs files between an Android device and your computer.
Like rsync, expects source and destination to be of the form THING:PATH,
or just PATH for the local filesystem. The difference is that adbsync
expects an Android device identifier instead of a hostnam for "THING".
Leave in the colon, but leave out "THING" if you want the defaut device.
(And actually, right now only the default device works.)
