the project is on github with this description (the copy-paste is partial):
------------
clj-sql

This package was written by developers that use clojure.contrib.sql but needed to add a few features to support their projects. Most of the functionality and API is inherited from clojure.contrib.sql

and the creator seems confident about it.

hi, do you think this project should go on ClojureDocs ? :)

Hi.

are you talking about clj-sql or clj-imajine? clj-sql should be more or less stable and is probably ready for general use. I'm still messing around a bit with clj-imajine, so any documentation on it might go out of date quickly. Still, might be worth adding anyway.

Cheers,
Joost.
