+% \subsubsection{Examples}
+% \DescribeEnv[<example code>]{example}
+% Perhaps the most powerful way to illustrate features of a package
+% is to show their function by examples. This is made possible by
+% the \env{example} environment. By enclosing example code in this
+% environment, the actual code is typeset next to the result it would
+% produce, as seen below\footnote{Note that the showcased \env{example}
+% environment doesn't contain another \env{example} environment --- the
+% environment is not intended to be nested inside itself.}\footnote{The
+% percent characters in the example are caused by the \pkg{docstrip}
+% requirement of prefixing the documentation with them.}:
+% \begin{example}
+% Simply typesetting a
+% \emph{paragraph} may
+% be simple enough, but
+% it should showcase
+% the utility of the
+% environment well enough.
+% \end{example}
+%
+% Note that for this to work the package obviously needs to be loaded.
+% As such, it is probably a good idea to combine the use of \env{example}
+% with the \opt{load} option, so be sure to read up on the caveats of
+% using that option (see page \pageref{ssec:options:load}).
+%
+% Since the \env{example} environment is based on the same mechanisms
+% as \env{MacroCode}, (mostly) the same typesetting properties apply.
+% In particular, the code will be highlighted if \pkg{minted} is
+% available. \Notice{Since the backend utilizes \cs{verbatim}, the
+% usual caveats apply. In particular, leaving whitespace before
+% \cs{end}\marg{example} will result in an extra newline at the end
+% of the displayed code.}

+% \subsection{Special case: syntax highlighting}
+% We support syntax highlighting through \pkg{minted}, but only if
+% we're running with unrestricted \cs{write18} access \emph{and}
+% there exists a suitable executable (\texttt{pygmentize}). Since
+% \pkg{minted} bails out without \cs{write18} access, we have to test
+% that before even loading it.
+%
+% \subsubsection{A simple \cs{write18} test}
+% Using the \cs{pdf@shellescape} macro from \pkg{pdftexcmds}, we
+% can define a new conditional that decides if we have unrestricted
+% \cs{write18} or not.
+% \begin{macro*}{\__skdoc_if_shellescape:T}
+% \begin{macro*}{\__skdoc_if_shellescape:F}
+% \begin{macro}{\__skdoc_if_shellescape:TF}
+% \begin{macrocode}

+ \if_cs_exist:N\pdf@shellescape
+% \end{macrocode}
+% If the command sequence exists (it really should), we test to see
+% if it is equal to one. The \cs{pdf@shellescape} macro will be zero
+% if no \cs{write18} access is available, two if we have restricted
+% access and one if access is unrestricted.
+% \begin{macrocode}
+ \if_int_compare:w\pdf@shellescape=\c_one
+ \prg_return_true:
+ \else:
+ \prg_return_false:
+ \fi:
+% \end{macrocode}
+% If the command sequence doesn't exist, we assume that we have
+% unrestricted \cs{write18} access (we probably don't), and let
+% \LaTeX\ complain about it later.
+% \begin{macrocode}
+ \else:
+ \prg_return_true:
+ \fi:
+}
+% \end{macrocode}
+% \end{macro}
+% \end{macro*}
+% \end{macro*}
+%
+% \subsubsection{Testing for an application}
+% In order to find out wether \texttt{pygmentize} is installed, we
+% have to test for its binary. This is done by shelling out to
+% \texttt{which} and reading a temporary file, which means we need
+% a way to delete that file.
+% \begin{macro}{\__skdoc_rm:n}[1]
+% {The file to be removed}
+% \begin{macrocode}
+\cs_new:Npn\__skdoc_rm:n#1{
+ \immediate\write18{rm~#1}
+}
+% \end{macrocode}
+% \end{macro}
+% Now, let's define the actual test. Note that this test will fail
+% on non-unixy platforms (\emph{i.e.} Windows). Deal with it for now.
+% \begin{macro*}{\__skdoc_if_pygmentize:nT}
+% \begin{macro*}{\__skdoc_if_pygmentize:nF}
+% \begin{macro}{\__skdoc_if_pygmentize:nTF}[1]
+% {The name of the binary to check existence of}
+% \begin{macrocode}
+\prg_new_conditional:Nnn\__skdoc_if_pygmentize:{T,F,TF}{
+% \end{macrocode}
+% First, run \texttt{which} to create the temporary file.
+% \begin{macrocode}
+ \immediate\write18{which~pygmentize~&&~touch~\jobname.aex}
+% \end{macrocode}
+% A temporary boolean is defined to hold the result of the test (this
+% is a bit of carco cult programming, any clues as to why placing the
+% result inside \cs{file_if_exists:nTF} doesn't work are welcome), and
+% if the test is successful we remove the temporary file.
+% \begin{macrocode}
+ \bool_set:Nn\l_tmpa_bool{\c_false_bool}
+ \file_if_exist:nT{\jobname.aex}{
+ \__skdoc_rm:n{\jobname.aex}
+ \bool_set:Nn\l_tmpa_bool{\c_true_bool}
+ }
+% \end{macrocode}
+% Finally, the temporary boolean is used to return a result.
+% \begin{macrocode}
+ \if_bool:N\l_tmpa_bool
+ \prg_return_true:
+ \else:
+ \prg_return_false:
+ \fi:
+}
+% \end{macrocode}
+% \end{macro}
+% \end{macro*}
+% \end{macro*}
+%
+% Using the macros defined above, we can test for both \cs{write18}
+% and \texttt{pygmentize}, loading \pkg{minted} and setting a flag
+% if both exist. If the option \opt{highlight} was supplied and set
+% to \texttt{false}, we do nothing.
+% \begin{macrocode}
+\ifskdoc@highlight
+ \IfFileExists{\skdoc@load.sty}{

+ \__skdoc_if_pygmentize:TF{
+ \bool_gset_true:N\g__skdoc_use_minted_bool
+ \RequirePackage{minted}
+% \end{macrocode}
+% Now that we have \pkg{minted}, we redefine the style of the line
+% numbers to match what we have further down for the non-highlighted
+% mode.

+% \texttt{pygmentize -S default -f latex}, with modifications. Note
+% the abundancy of \verb|#| characters; this is somewhat black magic,
+% but apparently \LaTeX\ expands them one more time than I'd expect
+% in this context. Probably a \LaTeX3 artifact. Also, the macro names
+% somehow correspond to Pygments entities (see \emph{e.g.}

+% The divider coffin, being dependent on the height of the two previous

+% specified earlier (by \cs{c__skdoc_example_linewidth_dim}). Margins

+% It's finally time to join and typeset the coffins. We clear a temporary

+% \section{Installation}
+% The easiest way to install this package is using the package
+% manager provided by your \LaTeX\ installation if such a program
+% is available. Failing that, provided you have obtained the package
+% source (\file{skdoc.dtx} and \file{Makefile}) from either CTAN
+% or Github, running \texttt{make install} inside the source directory
+% works well. This will extract the documentation and code from
+% \file{skdoc.dtx}, install all files into the TDS tree at
+% \texttt{TEXMFHOME} and run \texttt{mktexlsr}.
+%
+% If you want to extract code and documentation without installing
+% the package, run \texttt{make all} instead. If you insist on not
+% using \texttt{make}, remember that \file{skdoc.cls} is generated
+% by running \texttt{tex}, while the documentation is generated by
+% running \texttt{pdflatex}.
