SYNOPSIS
      xclone <filename>

DESCRIPTION
      Updates and clones an object. On error, the error log file will be
      printed. Moves the object (if possible) into your inventory. If the
      object has been cloned successfully, the variable "$clone" will be set,
      to make sure we don't lose the object out of sight :)

EXAMPLE
      xclone /std/thing
      xcall $clone->SetShort("a BIG thing!");
