This project is complete web application composed of:

• A command interpreter to manipulate data without a visual interface, like in a Shell (perfect for development and debugging)
  
• A website (the front-end) that shows the final product to everybody: static and dynamic
  
• A database or files that store data (data = objects)
  
• An API that provides a communication interface between the front-end and your data (retrieve, create, delete, update them)
  

The cmd interpreter provides a simple framework for writing line-oriented command interpreters.
It can be used for for test harnesses, administrative tools, and prototypes

The cmd module contains one public class, Cmd designed to be used as a base class for command processors such as interactive shells and other command interpreters.
By default it uses readline for interactive prompt handling, command line editing, and command completion.

It can be used to:

• Processing Commands
• Command Arguments
• Live Help
• Auto-Completion
• Overriding Base Class Methods
• Configuring Cmd Through Attributes
• Shelling Out
