[Python-Dev] Substantial rewrite of PEP 3101

[Talin]

I've rewritten large portions of PEP 3101, incorporating some material 
from Patrick Maupin and Eric Smith, as well as rethinking the whole 
custom formatter design. Although it isn't showing up on the web site 
yet, you can view the copy in subversion (and the diffs) here:

    http://svn.python.org/view/peps/trunk/pep-3101.txt

Please let me know of any errors you find, either by mailing me 
directly, or replying to the topic in Python-3000. (I.e. lets not start 
a thread here.)
