    <para>
      This package does not have a working testsuite. However, there is a
      useable basic graphical web browser in the build directory,
      <application>build/bin/MiniBrowser</application>. If launching it fails,
      there is a problem with the build.

    <note><para>
      When installing, the Makefile does some additional compiling and linking.
      If you do not have Xorg in /usr, the LIBRARY_PATH and PKG_CONFIG_PATH
      variables need to be defined for the root user.  If using sudo to assume
      root, use the -E option to pass your current environment variables for the
      install process.
