DESCRIPTION = "Secure rlogin/rsh/rcp/telnet replacement (OpenSSH) \
Ssh (Secure Shell) is a program for logging into a remote machine \
and for executing commands on a remote machine. \
It provides secure encrypted communications between two untrusted \
hosts over an insecure network.  X11 connections and arbitrary TCP/IP \
ports can also be forwarded over the secure channel. \
It is intended as a replacement for rlogin, rsh and rcp, and can be \
used to provide applications with a secure communication channel."
