// This program demonstrates processing of command-line parameters
//  using the UTIL library. Note: this only works if you have the
//  code for the UTIL library --- more generic command-line processing
//  will be covered later

//  To compile, save into mainCMD.cxx within Proto
//  and update Makefile to build from mainCMD.cxx instead of main.cxx
//  Then type make clean; make

#include <iostream>
#include "UTIL/paramproc.h"
