Subject Re: mysql-connector-python for marvin (was Re: [2/2] git commit: Summary: Replace pymysql with mysql-connector-python)

This classifies as a system dependency. It doesn't need to go in the
license, but also can't be packaged by our packaging specs (of
whatever type). Our packaging can set it as a dependency.

It should also be documented as a requirement in the appropriate
section of the README.
