[Twisted-Python] Understanding the role of .tap files

Wow, awesome reply.  That's by far the best explanation of .taps I've 
come accross.  Thank you!

Based on what you said, I'll probably use a simple python file for 
configuration, like so:

file "hepconfig.py":
field1='rasberry sorbet'
field3='cherry garcia'

Then my application can do something like this:

defaultConfig = {'field1': 'chocolate',
                  'field2': 'vanilla',
                  'field3': 'strawberry'}

import hepconfig
userKeys = filter(lambda f: not f.startswith('_'), dir(hepconfig))
userVals = [getattr(hepconfig, key) for key in userKeys]
userConfig = dict(zip(userKeys, userVals))

for key, val in defaultConfig.items():
     userConfig.setdefault(key, val)

... which results in userConfig containing:
{'field1': 'rasberry sorbet',
  'field2': 'vanilla',
  'field3', 'cherry garcia'}

Then I can have a single mktap option, 
--configfile=/path/to/hepconfig.py (which could be hard-coded in .debs 
and .rpms).  I think that strikes a nice balance between avoiding a 
special configuration language, and still being easy for sysadmins to 
figure out.

Does that seem like a reasonable approach?
