[mod_python] Error codes

Hi everyone.

I'm getting back into an old mod_python project I was working on a while
ago, and something has changed in regards to apache errors.

I have a bit of code which ends with:

else:
    raise apache.ERROR


I can't find anything in any mod_python documentation that even mentions
errors, other than to see the official apache docs. Unfortunately,
that's not useful since obviously "apache.ERROR" is a mod_python thing
and not an apache thing.

Can someone point me to the documentation detailing the list of apache
error codes and their uses?

Thanks!
