IRC_mention_notifier.rb

# PROBLEM: when someone replies to you publicly in an IRC channel you may not be 
# notified of it if you are away from your computer. The common format for public 
# replies looks like this:
#
#   <jchris> maxo_: yeah mine is way better
#
# SOLUTION: Sign up for notifo as both a supplier and a consumer, and install the 
# notifo app on your smartphone. Execute this in cron every minute to have new 
# mentions sent to your phone as push notifications. 
# 
# This is configured for IRSSI style logs, you can tweak the pattern matching to 
# match whatever logs you want
#
# You will also want to execute this once with the notifo.post line commented out 
# so that it adds all vestigial mentions to the running list of mentions to ignore
