Title: 
  Name clash at target
Goal: 
  Try to move the definition of macro `Person' from module `mr06' to the 
  header file `person.hrl'.
Parameters: 
  [{file,"mr06.erl"},{maclist,["Person"]},{filename,"person.hrl"}].
Documentation: 
  The transformation is refused because `person.hrl' already contains a
  macro definition `Person'. Moving another definition for macro `Person'
  into this file would cause a name clash.
