[Python-3000] py3k conversion docs?

[Guido van Rossum]

I haven't seen the patch you mention, and unfortunately there aren't
docs for the conversion yet.

However, one thing to note is that in 2.x, the PyString type ('str')
is used for binary data, encoded text data, and decoded text data. In
3.0, binary and encoded text are represented using PyBytes ('bytes'),
and decoded text is represented as PyUnicode (now called 'str').
Perhaps it helps understanding the patch knowing that 'char*' is
likely encoded text, while 'PyUNICODE*' is likely decoded text.

Sorry,
