\section{Demonstration: before and after}
 Let's give a demonstration of some before and after code -- after all, you probably won't
 want to try the script if you don't much like the results. You might also like to watch
 the video demonstration I made on youtube \cite{cmh:videodemo}

 As you look at \crefrange{lst:filecontentsbefore}{lst:pstricksafter}, remember that
 \texttt{latexindent.pl} is just following its rules, and there is nothing particular
 about these code snippets. All of the rules can be modified so that you can personalise
 your indentation scheme.

 In each of the samples given in \crefrange{lst:filecontentsbefore}{lst:pstricksafter} the
 `before' case is a `worst case scenario' with no effort to make indentation. The `after'
 result would be the same, regardless of the leading white space at the beginning of each
 line which is stripped by \texttt{latexindent.pl} (unless a \texttt{verbatim}-like
 environment or \texttt{noIndentBlock} is specified -- more on this in
 \cref{sec:defuseloc}).
