JCuckoo download page
Right now the only access to the files is via cvs. Please see this page for instructions how to use sourceforge.net cvs service. The module name is JCuckoo.
You can also browse the cvs repository via a www interface.
Please note that right now there are no tagged releases. The code in the cvs repository is not giaranteed to work at all. So if you are an user interested in using JCuckoo for your own purposes I suppose this will not be a big help to you. First alpha version however is quite close and will be usable so please keep your eye on the project!
