# == Synopsis 
#   This is a tool to help poolpartyrb and chef set haproxy.conf file.
#   It also can list clouds and add the new clouds to the chef server i
#   security group in order to let the chef clients connect to the chef server
#   TODO: list all the ips of a given cloud and list the passenger process(run
#   passenger-status remotly on each server).
#   Note: At the moment the script would work only if there is a cloud.rb in 
#   your cwd.
