Extract source URLs from RPM spec files

Hi,

I would like to create a probram that would download automatically the
source files of packages given a spec file and build it using rpmbuild.

But I just wonder how to extract the source URLs from the spec file. I can't
use standard srep and sed since often the Source line contains variables
that need to be resolved.

I found that rpm has an option --specfile that seems deigned for that
purpose. But rpm do not seems to be aware of the source filenames
unfortunately.

Does anyone knows how I could extract this information without writing a
spec file parser ?

Thanks.

Mildred
