	echo "will be merged to form the root directory of the cdr$suffix."
	echo
	echo "In order to place multiple directories in the cdr$suffix's root directory,"
	echo "you need to graft them into place. For example, to create a cdr$suffix"

	echo "Don't forget the slashes when grafting a directory into place"
	echo "or the cdr$suffix will contain its contents, not the directory itself."
	echo "See \"man mkisofs\" for more details."
	echo
	echo "The -i option treats the (single) non-option command line argument as the"
	echo "name of an iso9660 image file and burns it as an image, not as a file."
	echo "If you pass a single non-option command line argument to cdr$suffix, and"
	echo "it ends with \".cd\" or \".iso\", cdr$suffix will ask if you want it to assume"
