    ``qrmr get-config https://example.com/dev_config.json``

    Retrieves a JSON file or url with AWS Config profiles allowing AWS IAM 
    Assume Role operations.

    The ``~/.aws/credentials`` file should contain only `credential` profiles,
    while the ``~/.aws/config`` file should only contain `config` profiles with
    which one can role assume into other AWS accounts.

    You need to have your environments set up according to the AWS Well-Architected
    Framework meaning: a central AWS account with all IAM Users and AssumeRole
    permissions to other accounts, other accounts with IAM Roles with TrustRelationships
    to the central AssumeRole roles.

    This QRMR function allows you to publish a JSON file with config profiles 
    for different teams to ease setup and changes in IAM setup and terminal usage.
