This is just a proof-of-concept example for rbot druby-based api. This program
reads lines of text from the standard input and sends them to a specified irc
channel or user via rbot. Make sure you have remotectl.rb plugin loaded before
use.

The necessary setup is:
    1) # create a new rbot user ("rmuser", in this example) with a password
       # ("rmpw", in this example). in an open query to rbot:

       <you> user create rmuser rmpw
       <rbot> created botuser remote

    2) # add a remotectl permission to your newly created remote user:

       <you> permissions set +remotectl for rmuser
       <rbot> okies!

    3) # add specific permissions for the commands you want to allow via
       # remote interface. for example, in this script we want 'say',
       # 'action' and other basic commands to work:

       <you> permissions set +basics::talk::do for remote
       <rbot> alright

    4) # run the #{$0} and type something. the message should
       # show up on your channel / arrive as an irc private message.
       
       [you@yourhost ~]$ ./bin/rbot-remote -u rmuser -p rmpw -d '#your-channel'
       hello, world!
       <Ctrl-D>
       [you@yourhost ~]$

    exit 0
