-/**
- * <P>Primary class that drives overall FOP process.
- *
- * <P>Once this class is instantiated, methods are called to set the
- * Renderer to use, the (possibly multiple) ElementMapping(s) to
- * use and the PrintWriter to use to output the results of the
- * rendering (where applicable). In the case of the Renderer and
- * ElementMapping(s), the Driver may be supplied either with the
- * object itself, or the name of the class, in which case Driver will
- * instantiate the class itself. The advantage of the latter is it
- * enables runtime determination of Renderer and ElementMapping(s).
- *
- * <P>Once the Driver is set up, the buildFOTree method
- * is called. Depending on whether DOM or SAX is being used, the
- * invocation of the method is either buildFOTree(Document) or
- * buildFOTree(Parser, InputSource) respectively.
- *
- * <P>A third possibility may be used to build the FO Tree, namely
- * calling getDocumentHandler() and firing the SAX events yourself.
- *
- * <P>Once the FO Tree is built, the format() and render() methods may be
- * called in that order.
- *
- * <P>Here is an example use of Driver from CommandLine.java:
- *
- * <PRE>
- * Driver driver = new Driver();
- * driver.setRenderer("org.apache.fop.render.pdf.PDFRenderer", version);
- * driver.addElementMapping("org.apache.fop.fo.StandardElementMapping");
- * driver.addElementMapping("org.apache.fop.svg.SVGElementMapping");
- * driver.setWriter(new PrintWriter(new FileWriter(args[1])));
- * driver.buildFOTree(parser, fileInputSource(args[0]));
- * driver.format();
- * driver.render();
- * </PRE>
