Changes to rm.pas:
  - supports flags "f" and "r":
    "f" = don't ask any questions (DANGEROUS)
    "r" = delete directories (ask for confirmation, if no "-f")
So "rm -rf" is deadly, BEWARE!!!

Changes to cp.pas:
  - checks if drive is ready or write-protected
  - allows formatting of drive a:/b: if disk isn't formatted
    (you can force this with flag "-z")
-------------------------------------------------------------------
Changes to mv.pas:
  - checks if drive is ready or write-protected
  - renames files instead of copying if source and destination
    are on same drive (faster than copying) [Well almost ever]
  - allows formatting of drive a:/b: if disk isn't formatted
    (you can force this with flag "-z")
