   The copy code was based in GNU's cp, and was written by:
   Torbjorn Granlund, David MacKenzie, and Jim Meyering.

   The move code was based in GNU's mv, and was written by:
   Mike Parker and David MacKenzie.

   Janne Kukonlehto added much error recovery to them for being used
   in an interactive program.
