+          A simple Unix utility which reads and writes data across network
+          connections using TCP or UDP protocol. It is designed to be a
+          reliable "back-end" tool that can be used directly or easily driven
+          by other programs and scripts. At the same time it is a feature-rich
+          network debugging and exploration tool, since it can create almost
+          any kind of connection you would need and has several interesting
+          built-in capabilities.
+
+          This package contains the OpenBSD rewrite of netcat, including
+          support for IPv6, proxies, and Unix sockets.
