DocBookDoclet works like any other doclet . Consult http://java.sun.com/j2se/javadoc/ for further information on Javadoc and the Javadoc API. It can be invoked with default options by supplying the path to the doclet archive and the doclet invocation class (which is "org.dbdoclet.doclet.docbook.DocBookDoclet"). dbdoclet provides some doclet specific options. They are described in chapter Chapter 6.
