Lyrebot is a tiny IRC bot for forwarding messages to offline users.
You can build it using car:
$ car reqs # List dependencies.
$ opam install ... # Install the ones you don't have.
$ car opt # Build, output to ./main.native.
./main.native -help displays a help message:
$ ./main.native -help
Usage: lyrebot [options]

-help Print a synopsis of options.
-host The host to connect to.
-service The service or port to connect to.
-nick The nick to use. Also used for realname, user, etc.
-channel The channel to connect to.
Then when you send a message like this (in the channel or as a private message):
<jyc`> @jyc Long time no see! How are you doing?
... you get a confirmation as a private message:
<lyrebot> I'll forward your message the next time jyc logs in.
... and jyc gets a private message the next time he's online:
<lyrebot> *** You've got mail! ***
<lyrebot> 10:14 2/3 (5d ago) <jyc`> @jyc Long time no see! How are you doing?
