This document was written with GNU Emacs on FreeBSD. The XML sources use the DocBook XML DTD version 4.2. The images were created with Inkscape. The SVG files were then transformed to PNG and PDF using the Java application batik-rasterizer.
The document was transformed to the PDF and HTML output formats using xsltproc, FOP, and the DocBook XSL stylesheets through customization layers which are part of the documentation sources. The HTML output is further enhanced by a CSS file.
