@unnumbered
and @appendix
Use the @unnumbered
command to create a chapter that appears
in a printed manual without chapter numbers of any kind. Use the
@appendix
command to create an appendix in a printed manual
that is labelled by letter (`A', `B', ...) instead of by number.
Write an @appendix
or @unnumbered
command at the
beginning of a line and follow it on the same line by the title, as
you would if you were creating a chapter.
