Jon,

Thanks for the advice. It will still be a while until I have something
working but yes, I will create a merge request once I have a skeleton for
the importer.

@Jeff Young - I've made you an editor of the document I made on Pad Stacks
<https://docs.google.com/document/d/1lxBI7_X_I7pO-nuDHPRVlfRBH24XTmwuuN69o_Bqk3s/edit?usp=sharing>.
Hopefully you will have received a separate email with an editor's link.
Let me know if that wasn't the case.

Roberto
