Parameters (command line, preferences, user input)

I'm looking for a general way to handle a fairly large number of
parameters used by a program that I can apply to future work I do. These
programs are all command line programs and don't have a GUI.

I started implementing this for a project I'm working on and it just
seemed like something that someone else has to have done.

Ideally, what I would like is something like this:

1) Reads in default parameters from preferences.
2) Overrides these defaults using command line switches (long ones)
3) Prompt the user to input anything that is still required.
4) Writes out any changes the user made to preferences (not including
command line changes, probably). The user should be able to disable
this with a command line switch.

There should be a simple way of handling dependencies e.g. XoverProportion
doesn't matter since Xover wasn't selected so the user isn't prompted for
it.

Access to parameters should be very fast.

Is there some open source code out there for this?

Thank you,
