Non-standard versions

If you feel the need to make a version of LaTeX that differs from the standard version in ways that are not possible using the above configuration possibilities, then you should first read Modifying LaTeX in the file modguide.tex; this will probably make you realise that you do not have any such need.

Thus we are sure that you will never need to create a non-standard version and, even if you do create one, we hope that you will not distribute such a version. Nevertheless, you are permitted to do this provided you take great care to do the following:

• respect the conditions in legal.txt and individual files regarding modification of files and changing the name;
• change all the relevant `\typeout banners': i.e. those produced by all the non-standard files in your version and by the format;
• ensure that the method used to run your version is clearly distinguished from that used to run standard LaTeX; e.g. by using a command name or menu entry that is clearly different from latex (or LaTeX etc).
