%%% From KT: The example environment.   This is similar to verbatim, but only treats end
%%% of line and space as verbatim; control sequences, braces, and such work as
%%% before.  One situation in which this is useful is when you want to include
%%% italic text.  Unfortunately, if you include {\it stuff} the space between
%%% \it and stuff is typeset, since spaces are treated verbatim.  One way to
%%% avoid this is to type {\it{}stuff}.  A better way is to say \i{stuff}; \i
%%% is defined within example for just this purpose.

%%% We reuse as much LaTeX code as possible -- in a sneaky way by making
%%% \dospecials be a no-op, thus preventing the deactivation of the special
%%% characters.  Because special characters still work, we don't need the
%%% hackery needed by \endverbatim.
%%% Adjacent lines of an example environment get \examplepenalty inserted
%%% between them.  Beginning a line with \hinge removes the immediately
%%% preceding penalty.  Thus, setting \examplepenalty to 10000 prevents
%%% line breaks except between lines separated by \hinge.
