Tutorial
The Clojuratica Tutorial covers all of Clojuratica's features and is currently the only documentation.
The Tutorial is available in Mathematica Notebook (.nb) format and Adobe PDF format.
If formal, per-function documentation would be useful to you, please post a message on the Google group. It will be done eventually and requests would speed it up.
It is strongly recommended that you view the Tutorial in Mathematica Notebook format. The browsing is easier, the formatting is better, and the Mathematica code examples are executable.
If you do not have Mathematica, you can view the Tutorial using the free Mathematica Player, available for download from the Wolfram Research web site.
