• OS information (http://stackoverflow.com/questions/1854/how-to-check-what-os-am-i-running-on-in-python)
• Enchant dictionaries and relevant versions (?)
• pip freeze
• a short, text comment (being able to read it via a github diff screen would be great)
• a json schema for the shape of the score

We already store:

• The timestamp of creation
• The version of revscoring

Maybe also store:

• Hostname
• Username (on host)
• A PAWS "execution ID" that represents the kernel execution that trained the scorer model
