For using the addin in development mode, copy the addins folder from the
sandbox into the OpenLayers directory that also contains the lib, theme, img
and other folders. Add a script tag for
addins/timedpointtrack/trunk/lib/TimedPointTrack.js to your application's html.

For creating a single file build, copy the content of the
addins/timedpointtrack/trunk folder to the OpenLayers directory that also contains
the lib, theme and other folders. Add TimedPointTrack.js to the include
section of your build profile and do the build as usual. You do not need to
include an extra script tag in your html, because all required js is already
included in the OpenLayers single file build. You may, however, need to change
the OpenLayers.TimedPointTrackImgPath property (only if you also need to
change OpenLayers.ImgPath, and both locations are the same).

In both cases, add addins/timedpointtrack/trunk/theme/default/timedpointtrack.css
to as css resource to your html page.
