NAME
      smush - defocus an RLE image.

 SYNOPSIS
      smush [ -m maskfile ] [ -n ] [ -o outfile ] [ levels ] [ infile ]

 DESCRIPTION
      Smush convolves an image with a 5x5 Gaussian
      mask, blurring the image.  One may also
      provide a mask in a text file.  The file must
      contain an integer to specify the size of the
      square mask, followed by size*size floats.
      The mask will be normalized (forced to sum to
      1.0) unless the -n flag is given.

      The resulting image is the same size as the
      input image, no sub-sampling takes place.
      The levels option, which defaults to one,
      signifies the number of times which the image
      will be blurred.  Each successive blurring is
      done with a more spread out mask, so a smush
      of level 2 is blurrier than piping two level
      one smush calls.  If no input file is
      specified, smush reads from stdin.  If no
      output file is specified with -o it writes
      the result to stdout.

 BUGS
      Smush should probably automatically generate
      different sized gaussians and other common
      filters.
