  We have made the assumption that the user has the knowledge of 
  Object Oriented programing of C under Windows.

  This example will:
  1. load the image from a file, whose name is sent through the command line,
     using LFile::LoadFile(),
  2. display the image,
  3. save the image to the output directory using a callback and status
     window.

  Usage: SAVECB <filename> <output directory>
