code: def create_relocate_package(cls, package_name, shade_prefix=None, recursive=True):
      
      return cls.create_relocate(from_pattern=cls._format_package_glob(package_name, recursive),

docs: Convenience constructor for a package relocation rule.
  
      Essentially equivalent to just using ``shading_relocate('package_name.**')``.
  
      :param string package_name: Package name to shade (eg, ``org.pantsbuild.example``).
      :param string shade_prefix: Optional prefix to apply to the package. Defaults to
        ``__shaded_by_pants__.``.
      :param bool recursive: Whether to rename everything under any subpackage of ``package_name``,
        or just direct children of the package. (Defaults to True).
