# Maintain the JBoss DocBook system

The structure of the `docbook-support` module is illustrated in . The contents are as follows.

## The docbook-support module

- The `support` directory contains Java libraries and executables for XML processors. It also contains standard DocBook XSL stylesheets. This is the place for "system" software.
- The `styles` directory contains DocBook styles we developed in-house for JBoss. Each language would have a separate set of styles.
- The `docs` directory contains this guide to serve as a template for other projects.
- The `support.xml` file contains all the necessary ANT tasks to build DocBooks. It is referenced from the `build.xml` file for each individual DocBook project.
