+/*
+ * Compact Disc Control Utility by Serge V. Vakulenko <vak@cronyx.ru>.
+ * Based on the non-X based CD player by Jean-Marc Zucconi and
+ * Andrey A. Chernov.
+ *
+ * Fixed and further modified on 5-Sep-1995 by Jukka Ukkonen <jau@funet.fi>.
+ *
+ * 11-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
+ * A couple of further fixes to my own earlier "fixes".
+ *
+ * 18-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
+ * Added an ability to specify addresses relative to the
+ * beginning of a track. This is in fact a variation of
+ * doing the simple play_msf() call.
+ *
+ * 11-Oct-1995: Serge V.Vakulenko <vak@cronyx.ru>
+ * New eject algorithm.
+ * Some code style reformatting.
+ *
+ * 13-Dec-1999: Knut A. Syed <kas@kas.no>
+ * Volume-command modified. If used with only one
+ * parameter it now sets both channels. If used without
+ * parameters it will print volume-info.
+ * Version 2.0.1
+ *
+ * 27-Jun-2008 Pietro Cerutti <gahr@FreeBSD.org>
+ * Further enhancement to volume. Values not in range 0-255
+ * are now reduced to be in range. This prevents overflow in
+ * the uchar storing the volume (256 -> 0, -20 -> 236, ...).
+ * Version 2.0.2
+ *
