Fred Drake 9466b9a10d Add some (commented out) macros to change the page size to the size of
typical published manuals, so people can more easily see what they're
really asking for.  ;-)

Revise the verbatim environment: simple implementation, but more
compatible if a document also add \usepackage{verbatim} at the
beginning.

Declare \modindex, \bimodindex, \exmodindex, and \stmodindex
obsolete.  These still work just fine, but \declaremodule should be
used instead.  The obsolete macros will print a warning on standard
out.

% Example:
% \deprecated{1.5.1}{Use \method{frobnicate()} instead.}
