+The ``make.config`` file contains compiler specific parameters. You should change

 The ``configure.sh`` script will first download the
 [Ninja](http://github.com/martine/ninja) build tool, and will then run Ninja
 using the ``install/build.ninja`` file.  The configuration script will work in
 the ``install`` directory.  It will first download into the
