+       from an object in a memory view object.  If a copy is made then the
+       base object for the memory view will be a *new* bytes object. 
+       
+       Otherwise, the base-object will be the object itself and no 
+       data-copying will be done. 
+
+       The buffertype argument can be PyBUF_READ, PyBUF_WRITE,
+       PyBUF_SHADOW to determine whether the returned buffer
+       should be READONLY, WRITABLE, or set to update the
+       original buffer if a copy must be made.  If buffertype is
+       PyBUF_WRITE and the buffer is not contiguous an error will
+       be raised.  In this circumstance, the user can use
+       PyBUF_SHADOW to ensure that a a writable temporary
+       contiguous buffer is returned.  The contents of this
+       contiguous buffer will be copied back into the original
+       object after the memoryview object is deleted as long as
+       the original object is writable and allows setting an
+       exclusive write lock. If this is not allowed by the
+       original object, then a BufferError is raised.
+       
+       If the object is multi-dimensional and if fortran is 'F',
+       the first dimension of the underlying array will vary the
+       fastest in the buffer.  If fortran is 'C', then the last
+       dimension will vary the fastest (C-style contiguous).  If
+       fortran is 'A', then it does not matter and you will get
+       whatever the object decides is more efficient.  
+
+       A new reference is returned that must be DECREF'd when finished.
