Listings can be done fairly easily in LaTeX; one only has to include the \code{listings} package and start a new \code{lstlisting} block.

\lstset{language=[5.1]Lua,caption={A hello world program in Lua}}
\begin{lstlisting}
-- Comment
print "Hello World!"
\end{lstlisting}

\lstset{language=C,caption={The same program in C}}
\begin{lstlisting}
#include <stdio.h>
// Comment
int main() { printf("Hello World!\n") }
\end{lstlisting}

\begin{figure}[h]
	\centering
	\includegraphics{$HOME/image.png}
	\caption{An image}
	\label{fig:image1}
\end{figure}
