      Running the tests is not recommended. Failures will occur in the tests,
      depending on the screen resolution/capabilities, fonts installed and
      other X related parameters. Some tests may crash your X Server. To test
      the results anyway, issue: <command>make test</command>. Ensure you run
      it from an X Window display device with the GLX extensions loaded, but
      even so, tests may hang.

    <para>
      <parameter>$([ $(uname -m) = x86_64 ] &amp;&amp; echo
      --enable-64bit)</parameter>: This switch is used to enable 64 bit
      support in <application>Tk</application> on 64 bit operating
      systems.
    </para>

    <para>
      <command>make install-private-headers</command>: This command is
      used to install the <application>Tk</application> library interface
      headers used by other packages if they link to the
      <application>Tk</application> library.
    </para>

    <para>
      <command>ln -v -sf wish&tk-ver; /usr/bin/wish</command>: This
      command is used to create a compatibility symbolic link to the
      <command>wish&tk-ver;</command> file as many packages expect a file
      named <command>wish</command>.
    </para>

    <para>
      <command>sed -e ... tkConfig.sh</command>: The
      <application>Tk</application> package expects that its source tree is
      preserved so that packages depending on it for their compilation
      can utilize it. This <command>sed</command> removes the references to the
      build directory and replaces them with saner system-wide locations.
