%%

%% 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.
