#A script to post back to Slack via the webhooks API

##why this exists?

Slack's own hubot adapter needs the hubot installation to be accessible via web. This can be problematic in some cases, as a security risk.

This hack let's you run your Hubot behind a firewall, and connect to Slack via the IRC gateway.

To respond, Hubot uses the incoming webhooks end-point of Slack.

# This is a configuration script for using Rainbows with EventMachine. I'm providing it incase somebody finds it useful. But honestly, you 
# should stop using EventMachine and use threads instead. The ThreadPool version of this is also in my gist list, and I recommend taking a look at that instead.

# NO, SERIOUSLY, STOP USING EVENTMACHINE.
