-- SYNOPSIS
-- Define default internal macros.
--
-- DESCRIPTION
-- This file adds to the internal macro tables the set of default
-- internal macros, and for those that are accessible internally via
-- variables creates these variables, and initializes them to point
-- at the default values of these macros.
