Dear Python Patch Center:

This is my first Python patch submission. Apologies for
any errors of protocol. I have been using these
submitted changes for several years and have even given
it out (I mentioned it a few years back on a python
mailing list.) I am confident to the best of my ability
that these changes are solid.

Unfortunately I don't have the capability of rebuilding
the documentation, but the changes to the documentation
are outlined below.

Please do not hesitate to contact me for further
information or assistance. I would be honored to have
these changes become part of some Python revision, be
it 2.5 or something further in the future.

Thank you,
Eric Woudenberg

From my version of the wave.py file:

These changes allow .wav files containing u-law and
a-law data to be read and written. The user visible
changes are:

1) After a .wav file containing mu-law or a-law data is
opened for reading, a call to getcomptype() returns
'ULAW' (resp. 'ALAW') and a call to getcompname()
returns 'CCITT G.711 u-law' (resp. 'CCITT G.711 a-law').

2) After a wave object is created for writing,
setcomptype() can be called with the arguments ('ULAW',
'CCITT G.711 u-law') (resp. 'ALAW', 'CCITT G.711
a-law'). The second argument (text description) is ignored.

3) The comptype 'PCM' is now a synonym for 'NONE'.
PCM-containing wave files will return 'PCM' instead of
'NONE' for their comptype.
   
Note that this module does not do any u-law or a-law
format conversion to PCM, it simply allows users to
read or write u-law/a-law data from/to .wav files that
have conforming headers. For audio conversion of PCM
data to or from u-law, use the audioop module.

Patch applied to Python 2.4 wave.py

Patch applied to Python 2.5 wave.py

Please read http://www.python.org/dev/patches/
The best format for a patch is a "diff -u" format. It's much much easier
to see what you changed to the existing code, and the same patch often
applies to several versions.
Also, 2.4 and 2.5 are closed for new developments - your changes would
only go to a 2.7 version.

And your change is more likely to be accepted if it contains unit tests
(in Lib/test/test_wave.py)
