* last changes:
* 18.12.93 - first version, OK
* 01.01.94 - generalized & clean up HE
* 10.06.94 - first linux version HE
* 12.06.94 - wav header alignment problem fixed HE
* 12.08.94 - open the cdrom device O_RDONLY makes more sense :-)
* no more floating point math
* change to sector size 2352 which is more common
* sub-q-channel information per kernel ioctl requested
* doesn't work as well as before
* some new options (-max -i)
* 01.02.95 - async i/o via semaphores and shared memory
* 03.02.95 - overlapped reading on sectors
* 03.02.95 - generalized sample rates. all integral divisors are legal
* 04.02.95 - sun format added
* more divisors: all integral halves >= 1 allowed
* floating point math needed again
* 06.02.95 - bugfix for last track and not d0
* tested with photo-cd with audio tracks
* tested with xa disk
* 29.01.96 - new options for bulk transfer
* 01.06.96 - tested with enhanced cd
* 01.06.96 - tested with cd-plus
* 02.06.96 - support pipes
* 02.06.96 - support raw format
* 04.02.96 - security hole fixed
