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.
