# role, and one user, which is named for whoever is running the
# script, with a randomly generated password.

# Setting up permissioning in an empty database.

# What's messy here is that you need permission to add users,
# roles and firms --- but in an empty database, there are no
# records around which can give us permission to add any new
# records.  So, to avoid raw SQL, we have the following nonsense:
