    <para>
      If you wish to, test the installation of <application>SDL</application>
      using the included test programs. It is not required to install any of
      the resulting binaries to validate the installation. Issue the following
      commands to build the test programs:

    <para>
      You'll need to manually run all the test programs (they are listed in
      the <filename>README</filename> file in this directory).  Many of them
      will need to be manually killed, and you'll need to turn your speakers
      on with the volume at a suitable level.
