I wrote:

1. add an Include/pyexpat.h header file which contains a structure similar to the following:

2. during pyexpat initialization, initialize all members of this structure, and make it available as a PyCObject:

3. in cElementTree (or elementtree, or whatever the python version will be named), import pyexpat, fetch the object, and verify

4. in cElementTree (...), do all expat calls via the dispatch table.

I've fixed all this, and checked in 1 and 2.

the remaining issue is how to include cElementTree. the current stand- alone distribution consists of a single cElementTree module, which is in- stalled under site-packages, as usual.

to avoid collisions, it's probably best to install the bundled version under xml.etree, but how do you do that for a C module ?

my current idea is to

1.  include it under a different name (_elementtree.so)

2.  add a cElementTree.py under xml.etree, which simply does

        from _elementtree import *

does anyone have a better idea ?
