/*
 *	checknotes
 *
 *	A program which prints the notesfiles modified since the
 *	user's last entry. The output is a list of the modified
 *	notesfiles. 
 *	
 *	The program exits with a zero status if there ARE modified
 *	notesfiles, and non-zero if there are not. This is to
 *	correspond with the "true" and "false" programs and 
 *	to permit use of the program in shell scripts.
 *
 *	The optional "-q" parameter disables the printing of the
 *	names of the notesfiles, the exit code is the only metho
 *	of determining the existence of new notes.
 *
 *	Original Coding:	Ray Essick	June 12, 1982
