[mod_python] How do you specify the order in which mod_python Handlers are called?

I need to make sure multiple mod_python handlers are called in a specific order.
I also need to make sure they are before and/or after other "built in"
handlers such as mod_dav.

I am using Apache2 and mod_python 3.1.4, I can't find any examples or
specific details on this, and as I am not an Apache2 expert ( yet )
reading thru the apache docs is not going very fast.
