AutoScaling Setup
-----------------

This script helps to setup a autoscaling cluster without going through
the pain of figuring out how a API works. The only reason behind 
writing this script is to make things easier and faster.

This script is built on top of boto API for Python. You need to have 
Python boto 2.0 version pre installed on your machine to use this script.

This script brings together all peices needed by for setting up auto scaling, like
auto scaling configurations, load balancer configurations, cloud watch configuration, 
ec2 instances configuration etc and making this easier. You pass all the configurations
or parameters to a single script which gets job done sooner.


usage: autoscale.py [-h] --access-key <access key> --secret-key <secret key>

                         <load balancer> --min-size <minimum size> --max-size
