install/ports/libtelnet/pkg-descr

+From http://github.com/elanthis/libtelnet#readme:
+
+libtelnet provides safe and correct handling of the core TELNET
+protocol.  In addition to the base TELNET protocol, libtelnet also
+implements the Q method of TELNET option negotiation.  libtelnet can
+be used for writing servers, clients, or proxies.
