a framework for interactive, page-based console applications
The almanac framework aims to serve as an intuitive interface for spinning up interactive, page-based console applications. Think of it as a Python metaprogramming layer on top of Python Prompt Toolkit and Pygments.

"""Welcome to a simple interactive HTTP client.
The current URL to request is the application's current path. Directories will be
created as you cd into them.
