Code review comment for lp:~mwhudson/launchpad/recipe-db-schema

Hi there,

This branch adds the db schema for sourcepackagerecipes and associated things that was much discussed on the list. I've written a little code using this schema now (see lp:~mwhudson/launchpad/recipe-model-code) and it still feels more or less right and I would like to start landing code, so now seems like a good time to get this branch formally reviewed.

This presupposes a fairly boring way of representing recipes in the database -- but I think that this will be easier to change if we want to later.

Cheers,
mwh
