You need a cvs client (that works with your firewall, if any)

the repository name is
   @code{:pserver:anoncvs@@software.biostat.washington.edu:/var/anoncvs}

using a command-line cvs client (i.e. on Unix or DOS), first type:
   @code{cvs -d :pserver:anoncvs@@software.biostat.washington.edu:/var/anoncvs login}

password is anoncvs

then type:
   @code{cvs -d :pserver:anoncvs@@software.biostat.washington.edu:/var/anoncvs co ess}
