+Traitlets is a framework that lets Python classes have attributes with
+type checking, dynamically calculated default values, and 'on change'
+callbacks.
+
+The package also includes a mechanism to use traitlets for
+configuration, loading values from files or from command line arguments.
+This is a distinct layer on top of traitlets, so you can use traitlets
+in your code without using the configuration machinery.
