userv 1.1.1 (i386 binary) in ubuntu trusty

 userv allows one program to invoke another when only limited trust
 exists between them. It is a tool which can be used to avoid having
 to give other system services root privilege, and which allows users
 to more securely have programs provide services to others.
 .
 userv can be useful as `glue' for system administrators; there are
 not many full-blown userv-using applications yet.
