Version 0.3 alpha:
* NEC code debugged, quality not perfect (periodic noises)
* due to kernel fixes i could succesfully test the generic interface with 
*  nsectors > 1. this caused some fixes in my code.
* when recording with nsectors > 1 fixed the display 
*  (now increments in seconds)
* generic scsi interface changes introduced by kernel version 1.1.68 have been
*  followed
* index scanner still needs usleeps. maybe a toshiba 3401 bug?
* pressing ^c when using the generic interface may leave the process hanging

Version 0.2beta:
* fixed strange distortions when undersampling was not a power of 2
* fixed 44.1 / 16bit / mono recording
* fixed Makefile to propagate the HAVE_SOUND macro
* fixed kernel patch for Sony scsi drives
* changed default interface for SCSI from generic to ioctl again
* changed default generic device to /dev/sgc
* changed the -i option to allow recording to begin on a given 
  index
* set nsectors depending on device
* optimizations in the output conversion

Version 0.2alpha:
* added soundcard support (hear the pure digital sound :-)

Version 0.1:
* restructuring for more interface support
* added the generic scsi interface
* avoided sector copying for 1-to-1 conversion
* added the ioctl interface for sbpcd cdrom drives, FEEDBACK needed
* prepared routines for plextor and other cdroms, FEEDBACK needed
* increased MAXTRK from 30 to 100 allowing more tracks

Version 0.01:
* fixed open bug: used O_RDONLY instead of O_RDWR
* fixed tabs in Makefile
* fixed display when reaching a new index
* removed erasing of output file prior to writing. Now file can
  be /dev/null. 
* removed dos ASPI interface
* replaced floating point calculation by integer math.
* new option: -max select cd quality.
* new option: -i suppress sampling. just show info.
* new option: -e echo audio data to soundcard while recording
* new option: -n suppress recording to file
* some code cleanup, use more symbolic constants from cdrom.h.
  this requires newer kernel versions.
* sampling has become faster in avoiding a sector copy operation
* Toshiba 4101 is reported to work.
