# Author: Pieter Noordhuis
# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
#   the WebSocket protocol implementation in the cramp gem does not work
#   well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

# since there is no deb package for Ubuntu 8.04 LTS, this is what I had to do
# download latest stable version of mongodb and move to /usr/local/mongodb
# add "export PATH=$PATH:/usr/local/mongodb/bin" to /etc/profile
# make directories for the data /db/mongodb/master and /db/mongodb/slave
# chown those directories to the user you want
# move this script to /etc/init.d/mongodb
# chmod +x /etc/init.d/mongodb
# update-rc.d mongodb defaults
