+       This module contains JavaScript bindings based on gobject-introspection.
+
+       Because JavaScript is pretty free-form, consistent coding style and unit tests
+       are critical to give it some structure and keep it readable.
+       We propose that all GNOME usage of JavaScript conform to the style guide
+       in doc/Style_Guide.txt to help keep things sane.
