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
