Currently, there is are no formal releases of the BKNR environment. We are working with a Subversion repository which is publicy accessible. A big thanks to the folks at common-lisp.net for hosting our project!
The BKNR repository contains the framework, all software packages used by BKNR as well as well as several real-world applications which have been deployed in the internet. The application sources are provided as example material.
To check out the current state of the repository, please install the Subversion client on your machine and type
svn co svn://common-lisp.net/project/bknr/svn/trunk bknr-svn
This will store the source tree in the bknr-svn directory of your local file system. You may specify a different path if you wish.
The repository may also be browsed online.
