+    'description': '''
+This addon will show a confirmation dialog when the user closes
+a window with an OpenERP form containing unsaved data.
+
+This functionality is browser dependent. Opera ignores it at all,
+while Firefox displays a generic confirmation message.
+
+This module is compatible with OpenERP 7.0.
