You can use lrr_database.sql in this repo instead. LRR also needs to store assignment submissions. We store them in a folder called `../../lrr_submission`. Note that `lrr_submission` is two levels above the project folder (where many PHP files reside). I copied this folder from the existing one. I think it is also OK if you create an empty folder.
