\def\EveryVerbatimCodes{}

% \Verbatim is redefined temporarilly in \Get@Verbatim to scan the
% verbatim text. \Verbatim is used so that error messages are more
% enlightening. \next checks whether \Verbatim found its argument,
% and attempts to recover if not.
%
% Heuristically, if current environment is `foo' and argument of
% \Get@Verbatim is \The@Verbatim, then definition of \Verbatim is
%
% \def\Verbatim#1^^M#2^^M\the\EndVerbatimTokens\end{foo}{%
%  \xdef\The@Verbatim{\noexpand\Every@VerbatimLine#2}%
%  \endgroup\end{foo}}
%
% \The@Verbatim is then equal to the verbatim text, with spaces
% replaced by \Verbatim@Space, tabs replaced by \Verbatim@Tab,
% and ` replaced by \@lquote. In addition, each line begins with
% \Every@VerbatimLine, and each line but the last ends with
% \Verbatim@Par. It is then possible to redefine these when formatting
% the verbatim text. To insert each line as an argument to \foo, use
%   \def\Every@VerbatimLine#1\Verbatim@Par{\foo{#1}}
%   \The@Verbatim\Verbatim@Par
%
\newtoks\EndVerbatimTokens
