[Zope] Calling External Method...

// Geez, this is a pretty bad idea security-wise.  Your xCGI Python
// function has a docstring and is therefore web-callable, so basically
EEK!  You're right!  OK, that's fixed for now, but I thought I saw in this
mailing list that an external method was required to have a docstring.  What
role does the docstring play, exactly?  My ultimate goal is to be able to
run the C++ program from Zope, returning the results to a Zope generated web
page.  In your opinion, what's the best way to do that?

// I *think* this error message is telling you that it can't format the

I tried taking out the status code stuff and it didn't help.

Am I on the right track with this?  Shouldn't it be easy (& secure) to
launch a C app on the server and pipe the results back to Zope?  If so, how.
The approach I took (above) was recomended by someone else on the list.

Thanks for your help, Chris!
