% \paragraph*{Description.}
% This short package randomizes a list of tokens. The command, \cs{ranToks},
-% takes one argument, which is, in turn, a list of tokens:
-%\begin{verbatim}
-% \ranToks{<name>}
-% {
-% {tok_1}{tok_2}...{tok_n}
+% takes one argument, which is a list of tokens:
+%\begin{quote}\ttfamily
+% \string\ranToks\darg{\ameta{name}}\\
+% \darg{\\\null
+% \qquad\darg{\ameta{tok\SUB1}}\darg{\ameta{tok\SUB2}}...\darg{\ameta{tok\SUB{n}}}\\
% }
-%\end{verbatim}
+%\end{quote}
% The command defines a series of $n$ internal commands, one for each of the tokens.
% The definitions are essentially randomized. The randomized tokens are accessed through
% the command \cs{useRanTok}. For example
-%\begin{verbatim}
-% \useRanTok{1}, \useRanTok{2},..., \useRanTok{n}
-%\end{verbatim}
+%\begin{quote}\ttfamily
+%\cs{useRanTok\darg{1}}, \cs{useRanTok\darg{2}},..., \cs{useRanTok\darg{n}}
+%\end{quote}
% gives a random listing of the $n$ tokens. These can be arranged on the page
% as desired.
%
% There is a second construct, designed for more elaborate randomization.
