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.
