-/**
- * Class: OpenLayers.Control
- * Controls affect the display or behavior of the map. They allow everything
- * from panning and zooming to displaying a scale indicator. Controls by
- * default are added to the map they are contained within however it is
- * possible to add a control to an external div by passing the div in the
- * options parameter.
- *
- * Example:
- * The following example shows how to add many of the common controls
- * to a map.
- *
- * > var map = new OpenLayers.Map('map', { controls: [] });
- * >
- * > map.addControl(new OpenLayers.Control.PanZoomBar());
- * > map.addControl(new OpenLayers.Control.MouseToolbar());
- * > map.addControl(new OpenLayers.Control.LayerSwitcher({'ascending':false}));
- * > map.addControl(new OpenLayers.Control.Permalink());
- * > map.addControl(new OpenLayers.Control.Permalink('permalink'));
- * > map.addControl(new OpenLayers.Control.MousePosition());
- * > map.addControl(new OpenLayers.Control.OverviewMap());
- * > map.addControl(new OpenLayers.Control.KeyboardDefaults());
- *
- * The next code fragment is a quick example of how to intercept
- * shift-mouse click to display the extent of the bounding box
- * dragged out by the user. Usually controls are not created
- * in exactly this manner. See the source for a more complete
- * example:
- *
- * > var control = new OpenLayers.Control();
- * > OpenLayers.Util.extend(control, {
- * > draw: function () {
- * > // this Handler.Box will intercept the shift-mousedown
- * > // before Control.MouseDefault gets to see it
- * > this.box = new OpenLayers.Handler.Box( control,
- * > {"done": this.notice},
- * > {keyMask: OpenLayers.Handler.MOD_SHIFT});
- * > this.box.activate();
- * > },

- *
- * Handlers are created by controls, which ultimately have the responsibility

+/**
+ * Class: OpenLayers.Control
+ * Controls affect the display or behavior of the map. They allow everything
+ * from panning and zooming to displaying a scale indicator. Controls by
+ * default are added to the map they are contained within however it is
+ * possible to add a control to an external div by passing the div in the
+ * options parameter.
+ *
+ * Example:
+ * The following example shows how to add many of the common controls
+ * to a map.
+ *
+ * > var map = new OpenLayers.Map('map', { controls: [] });
+ * >
+ * > map.addControl(new OpenLayers.Control.PanZoomBar());
+ * > map.addControl(new OpenLayers.Control.MouseToolbar());
+ * > map.addControl(new OpenLayers.Control.LayerSwitcher({'ascending':false}));
+ * > map.addControl(new OpenLayers.Control.Permalink());
+ * > map.addControl(new OpenLayers.Control.Permalink('permalink'));
+ * > map.addControl(new OpenLayers.Control.MousePosition());
+ * > map.addControl(new OpenLayers.Control.OverviewMap());
+ * > map.addControl(new OpenLayers.Control.KeyboardDefaults());
+ *
+ * The next code fragment is a quick example of how to intercept
+ * shift-mouse click to display the extent of the bounding box
+ * dragged out by the user. Usually controls are not created
+ * in exactly this manner. See the source for a more complete
+ * example:
+ *
+ * > var control = new OpenLayers.Control();
+ * > OpenLayers.Util.extend(control, {
+ * > draw: function () {
+ * > // this Handler.Box will intercept the shift-mousedown
+ * > // before Control.MouseDefault gets to see it
+ * > this.box = new OpenLayers.Handler.Box( control,
+ * > {"done": this.notice},
+ * > {keyMask: OpenLayers.Handler.MOD_SHIFT});
+ * > this.box.activate();
+ * > },
+ * >

+ * Class: OpenLayers.Control

+ * default are added to the map they are contained within however it is
+ * possible to add a control to an external div by passing the div in the
+ * options parameter.
+ *
+ * Example:
+ * The following example shows how to add many of the common controls
+ * to a map.
+ *
+ * > var map = new OpenLayers.Map('map', { controls: [] });
+ * >
+ * > map.addControl(new OpenLayers.Control.PanZoomBar());

+ * > map.addControl(new OpenLayers.Control.LayerSwitcher({'ascending':false}));
+ * > map.addControl(new OpenLayers.Control.Permalink());
+ * > map.addControl(new OpenLayers.Control.Permalink('permalink'));
+ * > map.addControl(new OpenLayers.Control.MousePosition());
+ * > map.addControl(new OpenLayers.Control.OverviewMap());
+ * > map.addControl(new OpenLayers.Control.KeyboardDefaults());
+ *
+ * The next code fragment is a quick example of how to intercept
+ * shift-mouse click to display the extent of the bounding box
+ * dragged out by the user. Usually controls are not created
+ * in exactly this manner. See the source for a more complete
+ * example:

+ * > var control = new OpenLayers.Control();
+ * > OpenLayers.Util.extend(control, {
+ * > draw: function () {
+ * > // this Handler.Box will intercept the shift-mousedown
+ * > // before Control.MouseDefault gets to see it
+ * > this.box = new OpenLayers.Handler.Box( control,
+ * > {"done": this.notice},
+ * > {keyMask: OpenLayers.Handler.MOD_SHIFT});
+ * > this.box.activate();
