# Elixir Type specs cleaner v1.0.1
#
# I wanted to understand the time cost of having type specs in practically all
# our modules of a large Elixir codebase since, by using remote structs on type
# specs instead of struct references that would become a compile time
# dependency, we already saw some time improvements.
#
# Good (using `Bar.t`): `@spec foo(String.t) :: Bar.t`
# Bad (using `%Bar{}`): `@spec foo(String.t) :: %Bar{}`

This script emulates a stand-alone Python based client. It relies on Boto3 to access AWS, but
requires your Django server to have an API for your user to access Cognito based credentials

Because of Cognito, the client (this script) will only get temporary AWS credentials associated
to your user and only your user, and based on whatever you configure your AIM Policy to be.

Most Cognito examples demonstrate how to use Cognito for Mobile Apps, so this scripts demonstrate
how to create a stand-alone Python script but operating similarly to these apps.
