/*
   Make direct calls to process the various CLI option handling groups
   as defined in "MagickWand/operators.c" which uses a special
   MagickCLI type of 'wand'.

   This is essentually the calls 'ProcessCommandOptions()' make
   though without as many error and sanity checks.

   Compile with ImageMagick-devlop installed...

     gcc -lMagickWand -lMagickCore cli_operators.c -o cli_operators

   Compile and run directly from Source Directory...
