	I believe Christoper is now Chris Kane <Chris_Kane@next.com>.
	
	He has nothing to do with this compilation.  I just found the
	source code, compiled it, and thought it might come in handy.
	
	Usage is simple (see below).
	
	Tested under NeXT and Intel.  Compiled quadfat.

 
Usage: set-vol [-s] [-m | -M] [-l <left_vol>] [-r <right_vol>] [-v <vol>]
        Displays and optionally sets the mute and volume settings.
        Options: (in any order)
          -s  silent mode; settings are not displayed
          -m  unmute external speakers
          -M  mute external speakers
          -l  set volume of left speaker
          -r  set volume of right speaker
          -v  set both speakers; shorthand for '-l <vol> -r <vol>'
        If both -m and -M are specified, the rightmost of them has effect.
        The parameters <left_vol>, <right_vol>, and <vol> should be
        integers in the range 0 (minimum volume) to 43 (maximum volume).
