thanks to all the contributors who helped put this together. I'm not exactly sure of what's going to happen with this, but for now, at http://openlayers.org/dev/doc/examples.html you can see links to all the examples *with descriptions*. Hooray! git-svn-id: http://svn.openlayers.org/trunk/openlayers@5362 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf

<p>The above map has an overview map control that is created with
|
|
the default options. Much like a regular map, the map contained by
|
|
the overview map control defaults to a geographic projection.</p>
|
|
<div id="map2"></div>
|
|
<p>The second map has an overview map control that is created with
|
|
non-default options. In this case, the mapOptions property of the
|
|
control has been set to use non-default projection related properties.
|
|
In addition, any other properties of the overview map control can be
|
|
set in this way.</p>
