  # The upstream supports two configuration workflow:

  # one is to generate ./configure via `autoconf`,

  # the other is to run ./configure2.

  # ./configure2 is a configureation script included in the upstream source

  # that supports common "--<name>" flags and generates config.mak and config.h.

  # See INSTALL inside the upstream source for detail.
