File

Specifies the AWS Credentials file that will be used to both find the source Profile, and where to write the Session token data.

User

Specify the AWS User associated with the account. This is necessary if the profile's name is different than the one in AWS (or if you're using the default profile).

This may also be required if AWS Policies prevent the user associated with the credentials from listing all MFA Devices associated with the AWS Account.

Profile

Used to specify the AWS Profile in the credentials file for authenticating & generating a new session token. Default: default.

Session

Provide the name of the profile to create with the session token credentials. Default: session_profile

Duration

The lifespan of the session token, in seconds. Default: 3600 (1 hour).

Token

The token from the MFA Device. Can be provided via CLI; if not specified, user will be prompted.

Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
