descriptions from function or class docstrings

[thautwarm]

def f():
    """
    <doc>
    """

call(f)

Above code shall (pretty) print the docstring when using -h option.

Also I wonder if you'd support markdown rendering, and more customizable stuffs including pygments and custom renderers.

Can you provide some examples?

Some wonderful examples in python-prompt-toolkits:

You now can certainly use some markdown rendering package to convert them into HTML,
and use some HTML to terminal text styler to make a good-looking raw text output.

However I think as an argument parsing library, we'd better keep performant. You'd better writing some simpler and faster parsers and transformers to render markdown/pygments.
