+	  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.
