[Zope] ZopeProfiler and Kcachegrind, how to convert statistics files ?

[Jean-Michel FRANCOIS]

It's done, i m now able to use KCachegrind with ZopeProfiler. I have
patched pyprof2calltree to work with python2.4:

But something don't work : the call_info variable is not a sequence but
a integer, so i have fixed it like that:
