DocBook Njin is designed for our clients to convert docbook xml up to version 4.5 into PDF for their own uses. It is also available for free usage to the docbook community. Some sample xml docbook files are in the samplexml directory. It includes a java runtime (jre1.4.2) to run the apache FOP (0.94) software and the docbook xsl stylesheets (1.72.0) in the docbookNjin directory. Additionally our own customized stylesheets are used to render the docbook information.
