StreamReaderWriter Objects
..........................

The `StreamReaderWriter' allows wrapping streams which work in both
read and write modes.

The design is such that one can use the factory functions returned by
the `lookup()' function to construct the instance.

`StreamReaderWriter(stream, Reader, Writer, errors)'
     Creates a `StreamReaderWriter' instance.  STREAM must be a
     file-like object.  READER and WRITER must be factory functions or
     classes providing the `StreamReader' and `StreamWriter' interface
     resp.  Error handling is done in the same way as defined for the
     stream readers and writers.

`StreamReaderWriter' instances define the combined interfaces of
`StreamReader' and `StreamWriter' classes. They inherit all other
methods and attribute from the underlying stream.
