+password store in a Tomb and then keep your password tree encrypted when you
+are not using it.  It uses the same GPG key to encrypt passwords and tomb,
+therefore you don't need to manage more key or secret.  Moreover, you can ask
+pass-tomb to automatically close your store after a given time.")
