I'm designing a workbench that lifts some repetitive work from the
programmers' shoulders and that eases the combination of algorithms
that have been developed by different authors.

One part of the workbench is the support for command line parameters.
The workbench should provide the following features:

- modules announce their command line options to a centralized module
- the workbench parses the command line
- it provides the parameters to the respective modules
- it provides a help option, automatically compiled from all announced
options

Now my question: Is there a generic module around that has (some of)
these features?  I'm looking for something like log4j for logging.

Thanks,

Ulrich
