"""dbvault: Dropbox Encrypted Folders
This script makes it easy to set up, mount and unmount encrypted folders for use
in Dropbox. It depends on fuse-encfs in Linux.
To initialize it in a new Dropbox installation:
$ dbvault init
To mount later:
$ dbvault mount
And unmount:
$ dbvault umount
--Kirsle
