""" | |
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. | |
