--- Comment #3 from Erik Schilling ablu.erikschilling@googlemail.com --- Please upload your SRPM to a place which is accessible with a direct wget call. That allows tools like fedora-review (https://fedorahosted.org/FedoraReview/) to automatically detect the SRPM. Also you cannot download the SRPM from koji after the build is done. And the spec file alone is not enough since patches and sources are not included there.
The SRPM is a package which basically contains the .spec file together with all its dependencies (sources and patches mainly).
