3: * Compact Disc Control Utility by Serge V. Vakulenko <vak@cronyx.ru>.
4: * Based on the non-X based CD player by Jean-Marc Zucconi and
5: * Andrey A. Chernov.
6: *
7: * Fixed and further modified on 5-Sep-1995 by Jukka Ukkonen <jau@funet.fi>.
8: *
9: * 11-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
10: * A couple of further fixes to my own earlier "fixes".
11: *
12: * 18-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
13: * Added an ability to specify addresses relative to the
14: * beginning of a track. This is in fact a variation of
15: * doing the simple play_msf() call.
16: *
17: * 11-Oct-1995: Serge V.Vakulenko <vak@cronyx.ru>
18: * New eject algorithm.
19: * Some code style reformatting.
20: *
