+This is a simple TCP proxy written in Perl that uses IO::Socket::INET and
+IO::Select abstractions to create an evented (asynchronous, on select() call
+based) server.
+
+It was written by Peteris Krumins ([email protected]).
+His blog is at http://www.catonmat.net  --  good coders code, great reuse.
+
+I modified the proxy that I had written for my "Turn any Linux computer into
+SOCKS5 proxy in one command" article:
+
+    http://www.catonmat.net/blog/linux-socks5-proxy
+
+And wrote another article:
+
+    http://catonmat.net/blog/perl-tcp-proxy
+
+------------------------------------------------------------------------------
+
+Here is how it works:
+
+    $ ./tcp-proxy2.pl <local port> <host:port>
+
+This command proxies all tcp connections to <local port> to <host:port>.
+
+------------------------------------------------------------------------------
+
+Happy proxying!
+
