Create a new Tomb
=================
A Tomb is a special folder that keeps files safe using a password:
it makes use of strong encryption and helps you keep the keys on a
separate USB storage for safer transports.
Inside a Tomb you can store private informations without fear that
other people possessing it will discover your secrets, unless they
have your USB key and your password.
If you choose to proceed now, we'll guide you through the creation
of a new Tomb, You will also need the super-user (sudo) password for
the computer you are using.
If you will, I'll be your Crypto Undertaker.
Do you want to proceed, Master? (y/n)

Operation confirmed! we will now call the undertaker to do its
job, but in order to do so you will need to provide your sudo
password:
