"The :mod:`io` module provides the Python interfaces to stream handling. "
"Under Python 2.x, this is proposed as an alternative to the built-in :class:"
"`file` object, but in Python 3.x it is the default interface to access files "
"and streams."

"Since this module has been designed primarily for Python 3.x, you have to be "
"aware that all uses of \"bytes\" in this document refer to the :class:`str` "
"type (of which :class:`bytes` is an alias), and all uses of \"text\" refer "
"to the :class:`unicode` type.  Furthermore, those two types are not "
"interchangeable in the :mod:`io` APIs."

"At the top of the I/O hierarchy is the abstract base class :class:`IOBase`.  "
"It defines the basic interface to a stream.  Note, however, that there is no "
"separation between reading and writing to streams; implementations are "
"allowed to raise an :exc:`IOError` if they do not support a given operation."
msgstr ""

"Extending :class:`IOBase` is :class:`RawIOBase` which deals simply with the "

":class:`BufferedIOBase` deals with buffering on a raw byte stream (:class:"
"`RawIOBase`).  Its subclasses, :class:`BufferedWriter`, :class:"
"`BufferedReader`, and :class:`BufferedRWPair` buffer streams that are "
