-%The command \lstinline{\nimgame} presents the Nim game within \lstinline!\begin{center}...\end{center}!. An optional flag \lstinline{inline} can be used to produce the Nim game without the \lstinline{center} environment. For example, the command \lstinline!\nimgame[inline]{5,3,4}! will produce outline like this: \nimgame[inline]{5,3,4}
-%
-%One reason for this is that \lstinline{\nimgame} will not work in a \lstinline{standalone} document with the \lstinline{crop} option unless the \lstinline{inline} option is used.

 %There is no limit in the code to the number of piles or the number in a pile, but this code doesn't do anything to cope when line breaks start happening, and presumably there is a computational limit.

+% \begin{itemize}
+%    \item v1.1: added option to make inline Nim game.
+%    \item v1.2: \begin{itemize}
+%        \item switched \verb|\begin{center}| to \verb|\centering| (because the former doesn't work in \verb|standalone| documents and the latter doesn't add vertical space);
+%        \item removed some whitespace that appeared to the right of the last heap.
