NAME
       bwhist -	display	a histogram of a black and white bw file on a
       framebuffer

SYNOPSIS
       bwhist [-v] [file.bw]

DESCRIPTION
       Bwhist displays a histogram of the pixel	values in a bw(5) format file.
       If a file is not	given, standard	input is read. The output will be
       displayed on the	frambuffer selected via	the

       FB_FILE environment variable (see libfb(3)).

       The relative frequency is displayed on the x axis scaled	so that	the
       maximum is full screen. The value 0 is at the bottom of the screen, 255
       is at the top.  The output is overlaid on whatever is currently on the
       display.

       The -v flag will	output the histogram values on the terminal.
