[Distutils] Passing in arguments to Distribution?

I maintain the (rather large) PyOpenGL project, which is basically 4
core modules plus 300+ extension modules. One of the features I'd like
to allow for developers is to specify that, for instance, only 1 of the
extension modules be rebuilt during a setup pass (particularly during
development, it can take 3 or 4 minutes just to run the configs for all
the modules, which makes for very slow development).
The way the code currently works is that we override the Distribution
object's "finalize_options" to search out all of the .i (SWIG) files in
the interface sub-directory, creating an Extension object for each one
we find.
What I'd like to do is to tell the code running in the Distribution to
look for a global option (--extensions, for instance) and if it's
present, restrict the set of Extensions that's being built to the list
in the option.
However, I don't see a clean way of passing in arguments to the
Distribution object itself. It seems to be responsible for the parsing
of the command line, but it assumes that it's trying to parse options
for a particular command rather than for the overall process.
Any recipes someone cares to share? At the moment I'm thinking I may
just parse the options myself using getopt, but that seems like it might
cause pain somewhere down the road. I'm going to keep experimenting to
see if I can hack something in, but this seems like it would be a common
requirement, so I would imagine there's a lever somewhere I can throw...
At the moment I'm thinking of moving the module discovery code into the
main setup script, but that's still going to require parsing the options
myself... and that seems wrong somehow...
