Manipulating sets from the 2.4 C API?

[Dave Opstad]

I just looked through the Python/C API reference for 2.4.3 and didn't 
see anything about using sets. I'd been expecting things like PySet_New, 
PySet_Check etc.

If I want to handle sets should I just use a dictionary's keys and 
ignore the values, or is there some more explicit set support somewhere 
I'm not seeing?

Thanks,
