How to display source code with keyword highlighting and proper comment color

Originally posted at here

Include the package needed with the following line:

\usepackage{listings}

A template of quoting source code with syntax highlighting is as follows:

\usepackage{color}
\usepackage{listings}
\definecolor{Brown}{cmyk}{0,0.81,1,0.60}
\definecolor{OliveGreen}{cmyk}{0.64,0,0.95,0.40}
\definecolor{CadetBlue}{cmyk}{0.62,0.57,0.23,0}
\begin{document}

\lstset{language=VBScript,frame=ltrb,framesep=5pt,basicstyle=\normalsize,
keywordstyle=\ttfamily\color{OliveGreen},
morekeywords={one,two,three},
commentstyle=\color{Brown},
stringstyle=\ttfamily,
showstringspaces=ture}

\begin{lstlisting}
…
\end{lstlisting}

Adjust accordingly to your preferred language, style and color.
