This script runs a cake shell in the background with -d and should be placed in
your [App]/Console dir under the name "launch" etc.  Maybe good to execute local
worker instance.

	launch [options] [shell name]

	*or*

	launch [options] -s [shell name]

OPTIONS:
	-s	Cake shell you want to run (overrides non-option argument)
	-f	Maximum number of forks
	-d	Run in background
EOF
}

if [ "$1" = "help" ]; then
	usage
	exit 1

In the event that anyone finds this...don't use it. Use supervisord along with your normal blocking shells and let supervisord manage the process. http://supervisord.org/

Any tutorial to use cakephp with supervisor ?
