-# The workflow has a dropdown menu with two options:
-#
-# Build RPMs - Build release RPMs and tarballs and put them into an artifact
-#              ZIP file.  The directory structure used in the ZIP file mirrors
-#              the ZFS yum repo.
-#
-# Test repo -  Test install the ZFS RPMs from the ZFS repo.  On EL distos, this
-#              will do a DKMS and KMOD test install from both the regular and
-#              testing repos.  On Fedora, it will do a DKMS install from the
-#              regular repo.  All test install results will be displayed in the
-#              Summary page.  Note that the workflow provides an optional text
-#              text box where you can specify the full URL to an alternate repo.
