%% 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 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.
%% The names of the source files used are shown above.
