It looks as though setup_db.py and the www directory are still missing in the released version on pypi.
In trying to set up from scratch, no tables were being created on install (I'm using MariaDB/MySQL). The only way I could get it to work was to include the setup_db.py file and add the setup="pas.plugins.sqlalchemy.setup_db.prepare" line to configure.zcml as per the README. This is also not in the docs at pypi.
