    # 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.
