\begin{adjustwidth}{1cm}{1cm}
	\small
	\texttt{latexindent.pl} is a \texttt{Perl} script that indents \texttt{.tex} (and other)
	files according to an indentation scheme that the user can modify to suit their
	taste. Environments, including those with alignment delimiters (such as \texttt{tabular}),
	and commands, including those that can split braces and brackets across lines,
	are \emph{usually} handled correctly by the script. Options for \texttt{verbatim}-like
	environments and commands, together with indentation after headings (such as \lstinline!chapter!, \lstinline!section!, etc)
	are also available. The script also has the ability to modifiy line breaks, and add
	comment symbols. All user options are customisable via the switches in the YAML interface.

\subsection{The phases of \texttt{latexindent.pl}}
	With these rules in mind, let's study a few test cases:

	latexindent.pl environments-line-break-conflict.tex -s -t -m -o environments-line-break-conflict-mod1.tex -l=env-conflicts-mod1.yaml
	latexindent.pl environments-line-break-conflict-nested.tex -s -t -m -o environments-line-break-conflict-nested-mod-2.tex -l=env-conflicts-mod2.yaml
	latexindent.pl environments-line-break-conflict-nested.tex -s -t -m -o environments-line-break-conflict-nested-mod-3.tex -l=env-conflicts-mod3.yaml
	environments-first-opt-args.tex, see all of the different examples in test-cases.sh
	environments-second-opt-args.tex provides some interesting cases too

	The \lstinline!\fi! command knows to insert a space, so as to give, for example, \lstinline!\fi! text, and avoid things such as \lstinline!\fitext!

	from yaml
