lots of my settings are the same for different projects, i.e. where is the
accounting data, where are pdfs stored, etc.   So I end up with a system
that uses config settings at a user level and then project specific, or
overrides at the project level (machine or debug/production specific).
~/.yamjam/config.yaml + project/config.yaml

I like YamJam because it's just a light layer over pyyaml that handles
config setting merging intelligently.

May not be what you are looking for, but it would save you from
re-inventing your .cfg/.yml code to update settings.py.

Django needs some work there, storing db credentials and SECRET_KEY in a
piece of code that needs to be in a repository is troublesome.
