If you want to download the development code you have to checkout it from the
cvs repository:
(Warning: It is highly probable the development code will not work!)

$ cvs -d :pserver:anoncvs@hinezumilabs.org:/home/cvsroot login
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)


Once you've checked out a copy of the source tree, you can update
your source tree at any time so it is in sync with the latest and
greatest by running the command:
# cvs -z3 update -d -P

Or use github:
