GNU Rush is a Restricted User Shell, designed for sites providing
limited remote access to their resources, such as, for example,
savannah.gnu.org/. Its main program, rush, is configured
as a user login shell for users that are allowed only remote access
to the machine. Using a flexible configuration file, GNU Rush gives
administrator complete control over the command lines that users
execute, and allows to tune the usage of system resources, such as
virtual memory, CPU time, etc. on a per-user basis.
