This should go in `lib/fpm/package/rpm.rb` because it is so specific to rpm in both name and functionality, and it seems not applicable to any other package format.

Can you move these options?

The impact for your code is that all attributes will become prefixed with `rpm_` like `rpm_verifyscript`, and that the flags will be prefixed with `rpm-` like `--rpm-verifyscript`.

Let me knwo if you have questions about this! Happy to help :)
