#!/usr/bin/env ruby
# == this_cluster
# Script used to launch multiple server instances.
# It takes most of the same argument as the +thin+ script
# plus the -n option to specify the number of servers to run.
# 
# Also, you can store your options into a config file, create it like this:
#  thin_cluster config -C /var/www/my_app/current config
# Then a config file will be created in /var/www/my_app/current/config/thin.yml
# with the default options.
# You can launch your 3 servers with:
#  thin_cluster start
# And stop them with:
#  thin_cluster stop
#
# Run <tt>thin_cluster help</tt> to get help.
