� Z S )� MemoryBufferan Object interface to BIO_s_mem.
Empirical testing suggests that this class performs less well than
cStringIO, because cStringIO is implemented in C, whereas this class
is implemented in Python. Thus, the recommended practice is to use
cStringIO for regular work and convert said cStringIO object to
a MemoryBuffer object only when necessary.

This class interfaces Python to OpenSSL functions that expect BIO. For
general file manipulation in Python, use Python's builtin file object.

Its principal function is to be BIO_push()'ed on top of a BIO_f_ssl, so
that makefile() of said underlying SSL socket works.
