Hmm this seems to be truly broken:

I don't use Windows nor harbored-mod. Does anyone care about this? (feel free to pick up this PR)

At first glance this is #65

At first glance this is #65

Yup most likely - we only run dub build for Travis as well. I have rebased this PR to do the same (just building). We should probably switch back to dub test once #65 is fixed.

I opened an issue, s.t. it's not forgotten once this PR is merged:
