Schema-Checking for Configuration File

[pgierz]

The config file (aka user runscript, user script, whatever), should undergo a sanity check when loading to avoid erroneous entries and potentially confusing error tracebacks. I would recommend leveraging the cerberus library for this.

From the documentation:

CERBERUS, n. The watch-dog of Hades, whose duty it was to guard the entrance; everybody, sooner or later, had to go there, and nobody wanted to carry off the entrance. - Ambrose Bierce, The Devil’s Dictionary

Given that CMORization is one of those "the devil is in the details" tasks, I feel like this is an appropriate library to use 😉
