+Description: Allow users to claim directories on file systems
+ Machines sometimes have storage devices with useful special properties --
+ such as high performance, or secure erasure on power failure.  Rather than
+ set the root of such a filesystem world-writable and sticky, thereby making
+ another filesystem as hard to use safely as `/tmp', `claim-dir' lets users
+ claim directories on such filesystems via `userv'.  A newly claimed
+ directory is named after the calling user, and created readable and writable
+ only by the calling user -- so he or she can relax the permissions later if
+ necessary.
+ .
+ A script `mount-ephemeral' is included which allows the construction of an
+ ephemeral filesystem -- one which is backed by normal storage (typically in
+ `/tmp'), but encrypted using a temporary key which will be lost at reboot.
+ This script can be used to build a safe place for the storage of
+ temporary secrets.
