 ## Deprecated Components
 
 A number of properties, methods, and constructors have been marked as deprecated for multiple releases in the 2.x series.  For the 2.12 release this deprecated functionality has been moved to a separate deprecated.js file.  If you use any of the constructors or methods below, you will have to explicitly include the deprecated.js file in your build (or add it in a separate `<script>` tag after OpenLayers.js).
