Title: 
  Moving a macro to a module from a header used by multiple modules
Goal: 
  Try to move the definition of macro `Person' from the header file
  `person.hrl' to the module `mr09'.
Parameters: 
  [{file,"person.hrl"},{maclist,["Person"]},{filename,"mr09.erl"}].
Documentation: 
  The transformation is refused because `another.erl' includes `header.hrl',
  and `another.erl' already contains a definition `Person'. Moving
  another definition for macro `Person' into `header.hrl' would cause a 
  name clash in `another.erl'.
