      To test the results, issue:
      <command>dbus-run-session ninja test</command>. The tests
      require an active X session to run correctly. It is not necessary to
      run a  separate D-bus session if not in a GNOME session, but it
      provides a clean environment in any case. One test,
      <filename>native-headless</filename>, is known to fail.
