#   make              # install deps (repo-local) and serve at http://127.0.0.1:4000/
#   make HOST=0.0.0.0 # serve on all interfaces (e.g. when working on a remote box)
#   make build        # just build the site into _site/
#   make clean        # remove build output
#   make distclean    # also remove installed gems (vendor/)
