There are two ways to run the examples:

1. Oxygen XML provides an NVDL Processing Instruction (PI) that you can
place at the top of your XML document (after the XML declaration), e.g.

   
<?oxygen NVDLSchema="Book-Plus-NYtimes.nvdl"?>

Then you simply open the XML document in Oxygen XML and click on the 
validate button (the red checkmark).

2. Alternatively, open a DOS window, change to this directory, and then type:

  run

An NVDL processor, oNVDL, is already bundled in with this tutorial, so you should be
able to immediately run the examples.

No News Is Good News!  If all you see after typing "run" is "Done" 
then there were no errors in your NVDL script.
