This program examines and manipulates ICO files. The "-merge" command
packs multiple BMP and ICO files into a single ICO file.  The "-split"
command extracts the images from an ICO file into separate BMP files.
The "-info" command prints basic information about the images in an
ICO file.

usage:
  icoutilz -merge {file.ico | file.bmp mode}... -output icofile
  icoutilz -split -bmp file.ico...
  icoutilz -split -ico file.ico...
  icoutilz -info {file.ico | file.bmp}...

where mode is one of:
  -opaque       No transparency mask.
  -border       The most frequent color from the border of the image is
                used as the transparent color.
  -lowerleft    The color of the pixel in the lower left corner is
                used as the transparent color.
  -pixel x y    The color of the pixel at (x,y) is the transparent color.
                (0,0) is the lower-left corner.
  -palette n    The nth color in the palette is used as the transparent
                color.  The file.bmp must use a color palette.
                Numbering starts at 0, so the first color is 0.
  -rgb #rrggbb  The transparent color in hex.
  -rgb r g b    The transparent color in decimal, 0-255.
  -bmp file     'File' is a 2-color BMP file that is used as the
                transparency mask.

The "-split -bmp" command extracts the images into files named:
filename_wxhxb.BMP and filename_wxhxb_mask.BMP
where: w=width, h=height, b=bits-per-pixel.
The "_mask" file is the transparency mask for the image.
A counter is appended to the filename if there is more than
one image with the same width, height and bits-per-pixel.

The "-split -ico" works like the "-split -bmp" command except it
extracts the images into ICO files so there are no "_mask" files.
