+By default, the file extension from the containing file will automatically be included in the snippet name. For instance, the example above has `BEGIN-SNIPPET my-nice-example` in the JS source, and is subsequently referenced as `"my-nice-example.js"`.

+```js
+var app = new EmberApp({
+  includeFileExtensionInSnippetNames: false
