else the loader must create a new module object and add it to sys.modules.

B The __file__ attribute must be set. String say "<frozen>"
C The __name__ attribute must be set. If one uses
imp.new_module() then the attribute is set automatically.
D If it\'s a package, the __path__ variable must be set. This must
be a list, but may be empty if __path__ has no further
significance to the importer (more on this later).
