      # HEADS UP:
      # 1. The shiny server installation step will download various node
      #    and npm bits from the net.  They seem to have them well
      #    constrained ("npm shrinkwrap"?), but this package is not
      #    "air gappable".
      # 2. Docs say that it requires 'gcc'.  depends_on() won't do the
      #    right thing, it's Up To You.
