This book is written in Novdoc, a subset of DocBook (see
http://www.docbook.org). The XML source files were
validated by xmllint, processed by
xsltproc, and converted into XSL-FO using a customized
version of Norman Walsh's stylesheets. The final PDF is formatted through
XEP from RenderX. The open source tools and the
environment used to build this manual are available in the package
susedoc that is shipped with
openSUSE.
