cvsfs4hurd is a translator for the GNU Hurd, which allows to "mount" a CVS module into your local filesystem. It allows to view version controlled files as like they were regular files on your disk, however saving much network bandwidth.
This provides a package which presents the CVS contents as mountable file system.
It allows to view the versioned files as like they were ordinary files on a disk.
There is also a possibility to check in/out some files for editing.
