:Title: Printing a code listing
:Tags: Listings;Computer Science
:Author: Stefan Kottwitz
:Slug: listing

Documentation may contain code samples. The same applies
to theses in computer science. While pseudo-code of algorithms
was covered in the another example, we now like to typeset real code.
To save space, we will use a small "hello world" program as
example.

We will use the listings package which has been designed
for that purpose.

The code is fully explained in the LaTeX Cookbook, Chapter 11,
Science and Technology, Printing a code listing.
