You can set environment variables from the Supervisord config

I often tell clients to consolidate their config files, from all their various apps, inside of a folder inside of /etc (I assume Linux servers).

But an interesting alternative is to set the config in the Supervisord config, and thus consolidate all logging and config info in one place.

[program:django]
environment =
    SITE=domain1,
    DJANGO_SETTINGS_MODULE=foo.settings.local,
    DB_USER=foo,
    DB_PASS=bar
command = python manage.py command

One could simply have different entries for development, certain branches, and also the production service.
