"""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
