\subsection{The \texttt{auto} engine}
The automatic engine uses the tests and macros of the other engines
to provide functionality without selecting an engine. We first
define a conditional that, in essence, steps through the available
engines testing for their existence. If any of them exist, we're in
business.

\begin{MacroCode}{package}
-\prg_new_conditional:Nnn\__download_if_auto_test:{F}{
-\end{MacroCode}
- To avoid excessive nesting of conditional statements, we define
- a boolean (initialized to \cs{c_false_bool}) which we then set to
- \cs{c_true_bool} every time we find an engine that exists.
-\begin{MacroCode}{package}
- \bool_set:Nn\l_tmpb_bool{\c_false_bool}

- \__download_if_wget_test:T{\bool_set:Nn\l_tmpb_bool{\c_true_bool}}
-\end{MacroCode}
- We use that boolean to return a result from the conditional.
-\begin{MacroCode}{package}
- \if_bool:N\l_tmpb_bool
+\prg_new_conditional:Nnn\__download_if_auto_test:{F,TF}{

+ }{
+ \prg_return_false:
+ }
+ }
+ }
+ }
}
\end{MacroCode}
\end{macro}

- macros, which selects wget if possible and cURL as a second choice.

\Finale
+ \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{download.tex} 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{download.tex}, 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 packages distributed using
+ \pkg{skdoc} must be extracted using \texttt{pdflatex}, \emph{not}
