/**
   This class models the command-line of GraphicsMagick. 
   It extends the class GMOps and adds some utility-methods
   (like appendVertically()) not found in GraphicsMagick, 
   mainly for ease of use.

   <p>If you want to switch between GraphicsMagick and ImageMagick at
   runtime (using the system-property im4java.useGM=true),
   you have to limit yourself to the subset of options
   common to both implementations.</p>
