Hi,
I'm happy to release version 0.7.0 of the Promenade library. This release

If you enabled Log4j console logger, the logs should appear in the REPL too.

Btw, would you recommend using an ORM or straight java.jdbc and if an ORM,
any particular one you'd recommend?
ORMs are not prevalent in Clojure. You can use java.jdbc (the 0.3.x series
or later) with one of the SQL generators (HoneySQL, YeSQL etc) that you

The approach to read the database to generate code is pretty interesting.
There is a more portable way to extract the schema information, using
DatabaseMetadata that you can extract from a Connection.
