This is work in progress towards an importer that can import Stack 2.0 questions into Moodle. It was created by Matti Pauna working with Chris Sangwin and Tim Hunt.
To get this code, run
git clone git://github.com/sangwinc/moodle-qformat_stack.git question/format/stack
in the top-level folder of your Moodle install.
