+## Shit-simple script to supply the "privmsg <recipient>" of IRC typein, and
+## keep the connection alive.  Pipe this thru "nc -v -w 5 irc-server port".
+## Note that this mechanism makes the script easy to debug without being live,
+## since it just echoes everything bound for the server.
+## if you want autologin-type stuff, construct some appropriate files and
+## shovel them in using the "<" mechanism.
