+This module loads protocol metadata into python objects. It provides
+access to spec metadata via a python object model, and can also
+dynamically creating python methods, classes, and modules based on the
+spec metadata. All the generated methods have proper signatures and
+doc strings based on the spec metadata so the python help system can
+be used to browse the spec documentation. The generated methods all
+dispatch to the self.invoke(meth, args) callback of the containing
+class so that the generated code can be reused in a variety of
+situations.
