1Netcat 1.10 is an updated release of Netcat, a simple Unix utility which reads
2and writes data across network connections using TCP or UDP protocol.  It is
3designed to be a reliable "back-end" tool that can be used directly or easily
4driven by other programs and scripts.  At the same time it is a feature-rich
5network debugging and exploration tool, since it can create almost any kind of
6connection you would need and has several interesting built-in capabilities.
