+      '' GNU Rush is a Restricted User Shell, designed for sites
+         providing limited remote access to their resources, such as
+         svn or git repositories, scp, or the like.  Using a
+         sophisticated configuration file, Rush gives you complete
+         control over the command lines that users execute, as well as
+         over the usage of system resources, such as virtual memory,
+         CPU time, etc.
+
+         In particular, it allows remote programs to be run in a chrooted
+         environment, which is important with such programs as
+         sftp-server or scp, that lack this ability.
