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