+%% MODIFICATION ADVICE:
+%%
+%% If you want to customize this file, it is best to make a copy of

+%% 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 can then easily distribute your modifications by distributing
+%% the modified and renamed copy of the source file, taking care to
+%% observe the conditions in legal.txt; this will ensure that other
+%% users can safely use your modifications.
+%%
+%% 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.
