Setting up cvsfs on GNU/Hurd - A step by step process
Description of cvsfs
cvsfs is a virtual (libnetfs based) filesystem allowing you to mount remotely located CVS modules into your local filesystem. The version controlled files will appear to you just like regular ones. If you just want to view one file (or a small bunch) you furthermore save a lot of network bandwidth since only these files will be downloaded. The usual way to do so would be to check out the whole tree and deleting it after using.
Step by Step process in installing cvsfs
Download and prepare the source files from the CVS repositiory and build them.
$ cvs -z3 -d:pserver:anonymous@cvs.savannah.nongnu.org:/sources/hurdextras co cvsfs
$ cd cvsfs/
$ autoreconf -i
$ ./configure
$ make
$ make install
Set up the translator and start grazing.
$ mkdir -p cvsfs_test
$ settrans -a cvsfs_test /hurd/cvsfs cvs.sourceforge.net /cvsroot/projectname modulename
Example to mount the cvsfs module on hurdextras to a local directory.
$ mkdir cvs.d
$ settrans -ac cvs.d/cvsfs /hurd/cvsfs cvs.savannah.nongnu.org sources/hurdextras cvsfs
Now change to that directory and start using ls, emacs, and whatever you feel
like. 
Happy Hacking.
