	 *

	 *		inofficial (modified) version and thus may have bugs

	 *		cdrecord.
	 *
	 *		Or clearly state that there is absolutely no support
	 *		for the modified version you did create.
	 *
	 *	-	Tell the users not to ask the original author for
	 *		help.
	 *
	 * This limitation definitely also applies when you use any other
	 * cdrecord release together with libscg-0.6 or later, or when you
	 * use any amount of code from cdrecord-1.11a17 or later.
	 * In fact, it applies to any version of cdrecord, see also
	 * GPL Preamble, subsection 6.
	 *
	 * I am sorry for the inconvenience but I am forced to do this because
	 * some people create inofficial branches. These branches create
	 * problems but the initiators do not give support and thus cause the
	 * development of the official cdrecord versions to slow down because
	 * I am loaded with unneeded work.
	 *
	 * Please note that this is a memorandum on how I interpret the GPL.
	 * If you use/modify/redistribute cdrecord, you need to accept it
	 * this way.

	 * of cdrecord nor a new version of star from the original author
