Here are some approaches we've used:

1. Write a small script which sets PYTHONPATH and then calls the app.
   Make a different script for each setup you need.

2. Use a small script to set a couple of envvars, which in turn are
   used to find the right config file, which has all the config
   decisions you want.

archtool_path= os.getenv('ARCHTOOL_PATH')
archtool_cfg = os.getenv('ARCHTOOL_CFG')
sys.path.insert(0,archtool_path)
import archtool
exec "import archtool.%s as cfg" % archtool_cfg
