That module is a sort of simlink on my system, to the "sre" module.  
(Or the "pre" module if I were to uncomment one of the lines.)

Can someone explain why the code imports both from * and from "__all__" 
?  I've never seen the import __all__ before.  (It looks like this:

if engine == "sre":
     # New unicode-aware engine
     from sre import *
     from sre import __all__
else:
     # Old 1.5.2 engine.  This one supports 8-bit strings only,
     # and will be removed in 2.0 final.
     from pre import *
     from pre import __all__

thank you)
