`user services' - program call across trust boundaries

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.
