This app depends on the web2py framework, and it's used at 道德經. The app was built to study hanzi versions of the Dao De Jing in parallel and to publish my English interpretations thereof.

The app contains examples of how to use the unihan database, of how Python interpreters might share a common logger using the zero module, and of how to use the ipset XML-RPC server to blacklist and whitelist network addresses on localhost.
