Support Markdown file validation under longtest

[nazrulworld]

Hi, I am always used to the tool longtest to validate files that are included in setup.py. I am wondering if it is possible to validate Markdown files in the same way.

Thanks

I hardly ever use this command anymore. Instead I use restview --long-description, or restview CHANGES.rst if I expect problems in that file. See https://pypi.org/project/restview/

Other options:

• https://pypi.org/project/readme-renderer/
• With recent twine versions you can do python setup.py bdist_wheel && twine check dist/*, although this does not open a browser for a visual check.

I am not sure how well those handle MarkDown. I am still only using restructured text, though that may change.
