/// ## AWS
///
/// The `aws` module shows the current AWS region and profile and an expiration timer when using temporary credentials.
/// The output of the module uses the `AWS_REGION`, `AWS_DEFAULT_REGION`, and `AWS_PROFILE` env vars and the `~/.aws/config` and `~/.aws/credentials` files as required.
///
/// The module will display a profile only if its credentials are present in `~/.aws/credentials` or if a `credential_process` or `sso_start_url` are defined in `~/.aws/config`. Alternatively, having any of the `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, or `AWS_SESSION_TOKEN` env vars defined will also suffice.
/// If the option `force_display` is set to `true`, all available information will be displayed even if no credentials per the conditions above are detected.
///
/// When using [aws-vault](https://github.com/99designs/aws-vault) the profile
/// is read from the `AWS_VAULT` env var and the credentials expiration date
/// is read from the `AWS_SESSION_EXPIRATION` or `AWS_CREDENTIAL_EXPIRATION`
/// var.
///
/// When using [awsu](https://github.com/kreuzwerker/awsu) the profile
/// is read from the `AWSU_PROFILE` env var.
///
/// When using [`AWSume`](https://awsu.me) the profile
/// is read from the `AWSUME_PROFILE` env var and the credentials expiration
/// date is read from the `AWSUME_EXPIRATION` env var.
