  This format supports:
  </p><table border="0" summary="Simple list" class="simplelist"><tr><td><a class="ulink" href="http://www.humminbird.com" target="_top">Humminbird</a>
       waypoints and routes (<code class="filename">.hwr</code> files)</td></tr><tr><td><a class="ulink" href="http://www.humminbird.com" target="_top">Humminbird</a>
       tracks (<code class="filename">.ht</code> files)</td></tr><tr><td><a class="ulink" href="http://www.humminbird.com" target="_top">Humminbird</a>
       <code class="filename">.dat</code> files. (These accompany the
       <code class="filename">.png</code> files you get when you take snapshots.
       There are also <code class="filename">.dat</code> files generated when making
       recordings, but those are not supported here.)</td></tr></table><p>
</p><p>
  If you do "save all nav data" on the device, you'll get a 
  <code class="filename">data.hwr</code> and a <code class="filename">000.ht</code> file on the
  flash card (on a 797 in the <code class="filename">matrix</code> directory).
</p><p>
  The humminbird module can read all of these file formats, but you need to
  tell it which ones to write. By default, you get a <code class="filename">.hwr</code>
  file, to get a track (<code class="filename">.ht</code> file), use the
  "humminbird-track" format.
</p><p>
  </p><div class="informalfigure"><div class="mediaobject"><img src="humminbird.png" /></div></div><p> 
</p><p>
Note:<code class="filename">.dat</code> files are read-only, they only make sense
together with their images.
</p><p>
  Supported models:
  </p><table border="0" summary="Simple list" class="simplelist"><tr><td>797c2i SI</td></tr></table><p>
 (They should all work, but this is the only one tested so far.)
 </p><p>
  Known limits:
  </p><table border="0" summary="Simple list" class="simplelist"><tr><td>max 12 characters for waypoint names.</td></tr><tr><td>max 20 characters for route and track names.</td></tr><tr><td>max 50 points per route. Use <a class="link" href="filter_simplify.html" title="Simplify routes (simplify)">simplify</a> filter (count=50 or less) if you have routes with more points!</td></tr><tr><td>max 21835 points per track.</td></tr></table><p>
