"This is a skimpy overview; see the DeveloperGuide for the real meat."

I'm probably being stupid, but I can't find it. Can somebody point me in the
right direction please?

(Problem I'm trying to solve: I need to package up ruby-oci8 into RPM. I
need to decide whether I'd better served by packaging it as a gem, then
using gem2spec; or just packaging it as a native RPM. I've never built a
rubygem before so I need some "start here" documentation)

Thanks,

Brian.
