      Python Fire is a library for automatically generating command line
      interfaces (CLIs) from absolutely any Python object.

      * Python Fire is a simple way to create a CLI in Python.

      * Python Fire is a helpful tool for developing and debugging
        Python code.

      * Python Fire helps with exploring existing code or turning other
        people's code into a CLI.

      * Python Fire makes transitioning between Bash and Python easier.

      * Python Fire makes using a Python REPL easier by setting up the
        REPL with the modules and variables you'll need already imported
        and created.
