34
 * Compact Disc Control Utility by Serge V. Vakulenko <vak@cronyx.ru>.
35
 * Based on the non-X based CD player by Jean-Marc Zucconi and
36
 * Andrey A. Chernov.
37
 *
38
 * Fixed and further modified on 5-Sep-1995 by Jukka Ukkonen <jau@funet.fi>.
39
 *
40
 * 11-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
41
 *              A couple of further fixes to my own earlier "fixes".
42
 *
43
 * 18-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
44
 *              Added an ability to specify addresses relative to the
45
 *              beginning of a track. This is in fact a variation of
46
 *              doing the simple play_msf() call.
47
 *
48
 * 11-Oct-1995: Serge V.Vakulenko <vak@cronyx.ru>
49
 *              New eject algorithm.
50
 *              Some code style reformatting.
