\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 personalize 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}).
