/*! This is a test program to read a PrimList from an XML file and send it to the ROD.
It follows the format in Xml/README.rules and illustrated by Xml/Example.xml.
It retrieves any reply buffer generated by the PrimList and prints it to the screen.

This program can be called with optional arguments as follows:
-n :tells it not to initialize the ROD before sending it to the PrimList.
-s# where # is an integer between 1 and 21: set the VME slot number.
-f<filename>: set the name of the XML file to be read to be <filename>

If either -s or -f is missing, the user will be prompted for a value.
No space can come between -s and the slot number or between -f and the file name.

Examples:

./XmlTest -n -s7 -fXml/Exam[ple.xml
  This reads the file Xml/Example.xml and sends it to the ROD in slot 7 without calling
  the initialize() method of RodModule.
  
./XmlTest
  This executes the program, prompting the user for all information and initializing the
  ROD.
