Good way to write a C extension to Ruby?

< ^ > P N |<>|^_>< --- | ~ ...Help

Hi,

Whats a good way to write a C extension to Ruby?

I'm aware that there's a chapter about in the Pickaxe book (I think),
and will be checking that out, and also SWIG, if it supports Ruby. But
looking for replies from anyone who has already tried any of these
ways, and their feedback.

Thanks
