--
-- MODIFICATION ADVICE:
--
-- If you want to customize this file, it is best to make a copy of
-- the source file(s) from which it was produced. Use a different
-- name for your copy(ies) and modify the copy(ies); this will ensure
-- that your modifications do not get overwritten when you install a
-- new release of the standard system. You should also ensure that
-- your modified source file does not generate any modified file with
-- the same name as a standard file.
--
-- You will also need to produce your own, suitably named, .ins file to
-- control the generation of files from your source file; this file
-- should contain your own preambles for the files it generates, not
-- those in the standard .ins files.
