        Flux uses a fork of ZeroMQ's Collective Code Construction Contract
        (https://github.com/flux-framework/rfc/blob/master/spec_1.adoc).
        This model requires a repository fork for every stable release that has
        patch releases.  For example, 0.8.0 and 0.9.0 are both tags within the
        main repository, but 0.8.1 and 0.9.5 would be releases on the v0.8 and
        v0.9 forks, respectively.

        Rather than provide an explicit URL for each patch release, make Spack
        aware of this repo structure.
