/**
 * New lines in Java are handled differently than in C.
 * 
 * New line handling is system dependent.  In Windows it is \r\n, in
 * Unix, Linux, and OS X it is \n and in MAC OS 9 and earlier it was \r.
 * There are additional choices but that covers the present large deployments.
 *
 * C handles this by grabbing \n in String IO and mapping it correctly.
 * 
 * Java treats \n in strings as just another character so \n is not going
 * to get a newline in Windows (but works for many other operating systems).
 *
 * Java's first approach to handling the issue is to provide methods for
 * appending newlines  (System.out.println with newline as well as 
 * System.out.print without newline.)
 * 
 * Java "knows" the correct newline sequence (and many other system
 * dependencies) through configuration * settings which are accessible through
 * the System class.
 *
 * In this case, the property line.separator has the correct string for
 * providing a "newline" behavior on the present platform.
