or
$ export CVSROOT=":pserver:anoncvs@hinezumilabs.org:/home/cvsroot"
$ cvs login

then check it out:

$ cvs -z3 -d :pserver:anoncvs@hinezumilabs.org:/home/cvsroot co netsukuku
or
$ cvs -z3 co netsukuku
(providing the CVSROOT variable was set in the previous step)

your source tree at any time so it is in sync with the latest and

# cvs -z3 update -d -P
