+add_extension
+=============
+This command allows you to inject an external script code from the specified file into the current page.
+
+```json
+{
+ "name": "add_extension",
+ "args": [
+ "/www/web/script_extensions/extension.js"
+ ]
+}
+```
+If the script was properly injected the response should be:
+```json
+{
+ "response": "success"
+}
+```
+For more details on how this works check [PhantomJS injectJS documentation](http://phantomjs.org/api/webpage/method/inject-js.html)
