This is a collection of example programs to show how you can use the standard Python module docopt to handle command-line aruguments.

• one_arg.py: one positional argument
• nargs2.py: another way to handle two positional arguments
• nargs+.py: one or more positional arguments
• cat_n.py: a Python implementation of cat -n
• manual.py: manually validating an argument value inside get_args (using type-docopt)
• two_args.py: two positional arguments (automatic validating using Pydantic)
• choices.py: using choices to restrict values (automatic validating using Pydantic)
