1 /*
2 * Compact Disc Control Utility by Serge V. Vakulenko <vak@cronyx.ru>.
3 * Based on the non-X based CD player by Jean-Marc Zucconi and
4 * Andrey A. Chernov.
5 *
6 * Fixed and further modified on 5-Sep-1995 by Jukka Ukkonen <jau@funet.fi>.
7 *
8 * 11-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
9 * A couple of further fixes to my own earlier "fixes".
10 *
11 * 18-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
12 * Added an ability to specify addresses relative to the
13 * beginning of a track. This is in fact a variation of
14 * doing the simple play_msf() call.
15 *
16 * 11-Oct-1995: Serge V.Vakulenko <vak@cronyx.ru>
17 * New eject algorithm.
18 * Some code style reformatting.
19 *
