+/**
+ *
+ * Loader to add ol.css, ol.js and the example-specific js file to the
+ * documents.
+ *
+ * This loader is used for the hosted examples. It is used in place of the
+ * development loader (examples/loader.js).
+ *
+ * ol.css and ol.js are built with Plovr/Closure, based build/ol.json.
+ * (`make build` should build them). They are located in the ../build/
+ * directory, relatively to this script.
+ *
+ * The script should be named loader.js. So it needs to be renamed to
+ * loader.js from loader_hosted_examples.js.
+ *
+ * Usage:
+ *
+ *     <script src="../loader.js?id=my-demo"></script>
