"""
A script to query the Amazon Web Services usage reports programmatically.
Ideally this wouldn't exist, and Amazon would provide an API we can use
instead, but hey - that's life.
Basically takes your AWS account username and password, logs into the
website as you, and grabs the data out. Always gets the 'All Usage Types'
report for the specified service.
Requirements:
* Mechanize: http://wwwsearch.sourceforge.net/mechanize/
You can install this via pip/easy_install
Run with -h to see the available options.
