|
-- 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.
