Use Doxia as CMS Rendering Engine?

Hi,

I'd like to use Doxia (specifically Confluence Module) as an HTML-rendering engine in my CMS but I didn't see any code examples showing how to use it from regular java code.  Could someone please show me, or point me to an example of how to use Doxia to convert a string of text into HTML using the Confluence module, for example?

Thank you
