+.SH NAME
+nc \- TCP/IP swiss army knife
+.SH SYNOPSIS
+.B nc
+.I "[-options] hostname port[s] [ports] ..."
+.br
+.B nc
+.I "-l -p port [-options] [hostname] [port]"
+.SH "DESCRIPTION"
+.B netcat
+is 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.  Netcat, or "nc" as the actual program is named, should
+have been supplied long ago as another one of those cryptic but
+standard Unix tools.
+.P
+In the simplest usage, "nc host port" creates a TCP connection to the
+given port on the given target host.  Your standard input is then sent
+to the host, and anything that comes back across the connection is
+sent to your standard output.  This continues indefinitely, until the
+network side of the connection shuts down.  Note that this behavior is
+different from most other applications which shut everything down and
+exit after an end-of-file on the standard input.
+.P
+Netcat can also function as a server, by listening for inbound
+connections on arbitrary ports and then doing the same reading and
+writing.  With minor limitations, netcat doesn't really care if it
+runs in "client" or "server" mode -- it still shovels data back and
+forth until there isn't any more left. In either mode, shutdown can be
+forced after a configurable time of inactivity on the network side.
+.P
+And it can do this via UDP too, so netcat is possibly the "udp
+telnet-like" application you always wanted for testing your UDP-mode
+servers.  UDP, as the "U" implies, gives less reliable data
+transmission than TCP connections and some systems may have trouble
+sending large amounts of data that way, but it's still a useful
+capability to have.
+.P
+You may be asking "why not just use telnet to connect to arbitrary
+ports?" Valid question, and here are some reasons.  Telnet has the
+"standard input EOF" problem, so one must introduce calculated delays
+in driving scripts to allow network output to finish.  This is the
+main reason netcat stays running until the *network* side closes.
+Telnet also will not transfer arbitrary binary data, because certain
+characters are interpreted as telnet options and are thus removed from
+the data stream.  Telnet also emits some of its diagnostic messages to
+standard output, where netcat keeps such things religiously separated
+from its *output* and will never modify any of the real data in
+transit unless you *really* want it to.  And of course telnet is
+incapable of listening for inbound connections, or using UDP instead.
+Netcat doesn't have any of these limitations, is much smaller and
+faster than telnet, and has many other advantages.

+.SH COPYRIGHT
+Netcat is entirely my own creation, although plenty of other code was
+used as examples.  It is freely given away to the Internet community
+in the hope that it will be useful, with no restrictions except giving
+credit where it is due.  No GPLs, Berkeley copyrights or any of that
+nonsense.  The author assumes NO responsibility for how anyone uses
+it.  If netcat makes you rich somehow and you're feeling generous,
+mail me a check.  If you are affiliated in any way with Microsoft
+Network, get a life.  Always ski in control.  Comments, questions, and
+patches to hobbit@avian.org.
+.SH BUGS
+Efforts have been made to have netcat "do the right thing" in all its
+various modes.  If you believe that it is doing the wrong thing under
+whatever circumstances, please notify me and tell me how you think it
+should behave.  If netcat is not able to do some task you think up,
+minor tweaks to the code will probably fix that.  It provides a basic
+and easily-modified template for writing other network applications,
+and I certainly encourage people to make custom mods and send in any
+improvements they make to it. Continued feedback from the Internet
+community is always welcome!
+.P
+Some port names in /etc/services contain hyphens -- netcat currently
+will not correctly parse those, so specify ranges using numbers if you
+can.
