AWS CLI OVA2AMI and ISO2AMI

I would like a simple aws command-line to convert an OVA I already have into an AMI image. Additionally, I'd love to do an ISO to AMI image with a second command.

Note, I'm looking at the awscli package from pip:

pip install awscli

I have a 2-hour build process that produces an ova appliance (as well as an ISO). I'd really like to add to my automated process so I can also dump out an AMI file for developer use on an AWS instance.

I'm a heavy python user, so I have preference for a pythonic solution. I would absolutely prefer to use yaml as my configuration and not run aws configure on my build box.

I'm completely new to AWS. The documentation is overwhelming and it doesn't appear to be easily referenced in a way that makes sense to me. After spending a few hours attempting to understand the landscape, I'm no where near providing myself with a solution.
