Do you prefer to spend your time writing a program, or writing the interface layer (which handles the command-line options and subcommands, tests them for validity, opens files, etc.)?

Wouldn't it be great if you could just indicate how your command-line interface should work and let something else take care of the details? Good news: Click can do this! It uses decorators, so as to keep your interface functions concerned only with business logic, i.e. dealing with the problem domain. Click has a large set of classes that make it easy to specify the type of your command-line options and arguments, and create custom types if you want. And it generates online help messages, which can be enhanced by optional descriptions that you add to your option specifications.

This talk will give an overview of how to create a Python command-line tool using setup.py packaging, with entry points.
