---------------------------------------------------
5/2/95
0.2c alpha
***

IMPORTANT NOTICE!!!!!!!!

- IF YOU HAVE A VERSION BEFORE THIS, please
  upgrade and delete your old versions from 
  0.1b through 0.2b


- NEW FFT routine!  Rather, actually the previous
  one I've been using, and the frequencies 
  should be a bit more accurate now, although
  I haven't tested too much (see below).  I think
  some frequencies were missing in previous versions.
  IT IS IN FORTRAN AGAIN, but it works quite well


***
- I can't believe this happened, but, apparently
  the fft code I was emailed was unbeknownst to me
  under a special copyright restriction and since
  _HAS BEEN COMPLETELY REMOVED_.  PLEASE REMOVE
  VERSIONS 0.1b-0.2b if you find them.

  If you contribute code that is fine, just be
  _sure_ where you got the code from and any
  restrictions placed upon its use.  I would have
  _never_ included the code if I had known this.
  The ffts now in place are from netlib
  (netlib.att.com) and are under the netlib policy.

Contributions
-------------
- C ffts from Andreas Schiffler  (F77 not req.)
- spectral windowing from Tatsuo Miyachi

Other
-----
- 16-bit support (some defaults have changed)
- multiple screen resolutions up to 1024x768x256,
  now defaults to 640x480x256 
- on-the-fly changing of sampling rate, bit resolution, 
  screen resolution + more
- added automated zero-calibration
- more command-line options
- more parameter configuration
  e.g. can now revert to all command-line defaults 
- quick-reference screen added (press ?)
- updated man page
- better frequency labeling
