+A list of xstatic modules containing javascript and scss files to be included
+in the compressed set of files that are loaded on every page. Related files
+specified in ``ADD_XSTATIC_MODULES`` do not need to be included in
+``ADD_JS_FILES``. This option expects a list of tuples, each consists of
+a xstatic module and a list of javascript files to be loaded if any.
+For more details, please check the comment of ``BASE_XSTATIC_MODULES``
+in openstack_dashboard/utils/settings.py.
