I've just installed Grive from a opensuse package, and no problem.
Did the grive -a , inserted the key - no problem.

But then, I don't understand how it works, because, first it starts to
sync a folder that I didn't want it to sync, nor I know why Grive choose
that particular folder.

I've moved the .grive from that folder to a folder that I want to be
sycn, I call it Drive.

I try to call grive, but it was necessary to do grive -a again. ok,
insert another key again.

But then, he stared to sycn all my Home folder .... not sure way.

Is there something that I'm missing here ?
