Dependency Generators in RPM < 4.9

[T.C. Hollingsworth]

Hi!

For nodejs, we drop a file in /usr/lib/rpm/fileattrs to automatically
generate Provides and Requires based on the metadata shipped with
every Node.js module.  I understand that this isn't supported on RPM <
4.9 (e.g. all current versions of RHEL), but it seems to have some
sort of older generator system [1] we can use?  How do we go about
that?

Thanks!
