* This PHP script reads points from a database and outputs a text formatted

* In the absence of bbox param it reads all points from the database.
*
* You can point OpenLayers directly at this php script. Optionally you can then
* use a BBOX strategy. This tells OpenLayers to add on a 'bbox' parameter,
* which this script can use to limit the number of points returned.
