The macro tt(ATEXIT) takes one parameter list as argument. The text of the
parameter list is appended to the output file. Note that this text is subject
to character table translations etc..

A good example of the usage of this macro is the following. A document in the
LaTeX typesetting language requires tt(\end{document}) to occur at the end of
the document. To automatically append this string to the output file, the
following specification can be used:

verb(ATEXIT(NOEXPAND(\end{document})))

Several tt(ATEXIT) lists can be defined. They are appended to the output file
in the bf(reverse) order of specification; i.e., the first tt(ATEXIT) list is
appended to the output file last. That means that in general the tt(ATEXIT) 
text should be specified when a `matching' starting command is sent to the 
output file; as in:

verb(\
COMMENT(Start the LaTeX document.)
NOEXPAND(\begin{document})

COMMENT(Make sure that the ending is
        on time.)
ATEXIT(NOEXPAND(\end{document})))
