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