// Function: main

// Purpose:
//   Writes out a Java class that contains VisIt's version number. The class
//   is autogenerated so we don't have to keep doing it by hand.
//
// Notes:      
//
// Programmer: Brad Whitlock
// Creation:   Wed Aug 21 12:24:23 PDT 2002

//   Get the input and output file from the command line.
