Fred Drake 7b8195a209 \programopt: New macro, used to mark command-line parameters in the 
text.  Looks like \program.

\citetitle:   New macro, used to mark titles of cited works (like the
              names of the Python manuals).  Accepts & discards an
              optional parameter that is only used by the HTML
              formatter.  Looks like \emph.

% Deprecation stuff.
% Should be extended to allow an index / list of deprecated stuff. But
% there's a lot of stuff that needs to be done to make that automatable.
%
% First parameter is the release number that deprecates the feature, the
% second is the action the should be taken by users of the feature.

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