The project uses a publicly accessible CVS code repository. The latest source as well as all the documentation may be checked out with the following command line:
cvs -d :pserver:email@example.com:/home/cvs co vfer
The CVS repository on sourceforge is not used by the project, it will only contain snapshots of the work. Please use the Internet2 repository for the latest updates.
At the moment, the project has a beta release.
The doxygen html documentation for the project can be found here.
