Description

We have run into more than one publisher supplied question banks that are too large to be imported by Moodle without hitting a PHP memory limit. In this particular case they are in Blackboard format with many chapter files.

I'll see if I can make one manually that will do the same thing - I can't supply the problem ones for copyright reasons.
