This file would be read in setup.py file while packaging and distributing the library.

But this standard still had one problem — there was always a chance of misconfiguration while setting up CI/CD pipeline. Hence, errors like ending up with an outdatedIf you are interested in learning more about what has been deprecated and what are the new alternatives, you can check thisThe new packaging standard is not directly compatible with the commonly used virtual environment tools.
