	Usage: check_fileage -f /mount/path/file.ext -w nnnn -c nnnn [-d A|C|M] [-V] [-h]
	
	Options:
	 -h, --help
	    Print detailed help screen
	 -d, --datetype
	    Date Type: Return the date as defined:
	            A: (time of most recent access),
	            M: (time of most recent content modification),
	            C: (platform dependent; time of most recent metadata change on Unix, or the time of creation on Windows).
	            The default is M.
	 -f, --file
	    The absolute path and file name.
	 -w, --warning
	    The age of the file in minutes to generate a warning notification.
	 -c, --critical
	    The age of the file in minutes to generate a critical notification.
	 -x, --fail-on-not-exists
	    Returns WARN if the file does not exist.
	 -X, --ok-on-not-exists
	    Returns OK if the file does not exist.
	 -V, --version
	    State the Version
	
	Examples:
	    check_fileage -f /path/to/file -w 1440 -C 2880
	        Returns OK if the file is less than the warning time in age.
