I concur. zmqd user code looks much cleaner than the original C code. Kudos to you! I also like the docs. I see you used your own ddoc file (https://github.com/kyllingstad/ltkdoc). Clean and to the point. I might steal it :) Btw, there should be a place to put third parties ddoc templates. Maybe a wiki page?
