NAME
      graytorle - Merges gray scale images into an
      RLE format file.

 SYNOPSIS
      graytorle [ -a ] [ -h hdrsize ] [ -o outfile ] xsize ysize infiles

 DESCRIPTION
      Graytorle reads a list of 8-bit gray scale
      images in unencoded binary format and
      converts them to an RLE(5) image with the
      number of channels corresponding to the
      number of input files.  A command line option
      allows specifying one of the files as an
      alpha channel.

 OPTIONS
      -a   Designates the first file in the input
           list as being information for the alpha
           channel of the image.

      -h hdrsize
           Often gray scale image files include
           some sort of header information.  This
           option allows specification of a count
           of bytes to discard at the beginning of
           each input file.

      xsize
           Specifies the horizontal resolution of
           the input files.

      ysize
           Specifies the vertical resolution of the
           input files.

      -o outfile
           This option is used to name the output
           file.  Otherwise, output is written to
           stdout.

      infiles
           List of input files.
