  <para>
    The <command>version</command> helper command states the configuration
    file version.
  </para>
  <para>
    If the value passed is newer than the running version of
    <application>Sanewall</application> supports,
    <application>Sanewall</application> will not run.
  </para>
  <para>
    You do not have to specify a version number for a configuration
    file, but by doing so you will prevent <application>Sanewall</application>
    trying to process a file which it cannot handle.
  </para>
  <para>
    The value that <application>Sanewall</application> expects is increased
    every time that the configuration file format changes.
  </para>
