Demo EXE HTTP Service

This is a simple HTTP service that can be used to demonstrate the use of PyInstaller to create an executable from a Python script that is a web server. The components of the service are:

• A cli.py Python script that prints hello world for the user.
• A README.md file that describes the service and how to use it.
• A LICENSE file that contains the MIT license for the service.
• A requirements.txt file that lists the Python packages required by the service.
• A requirements.in file that is used to generate the requirements.txt file.
• A Makefile that contains targets for building and cleaning the service.
• A make.bat file that contains targets for building and cleaning the service on Windows.
