## 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.
