Here's a quick of how to get GATOS via anonymous CVS.

        Using CVS:
        
With tcsh:
        setenv CVSROOT :pserver:cvs@cvs.core.binghamton.edu:/usr/local/CVS
With bash:
        export CVSROOT=:pserver:cvs@cvs.core.binghamton.edu:/usr/local/CVS

Then with either:
        cvs login
                -No password, just hit enter you only have to do this the first time.
        cvs checkout gatos ibtk
                -This will create a gatos and an ibtk dir.
        cd ibtk; ./configure; make; make install; cd ..
                -Makes sure you have the newest ibtk.
        cd gatos; ./configure; make; make install
                -installs xatitv + atitv + atito* in /usr/local/bin.

                -Then try it out, and let me know how it works, make sure
to tell me exactly WHEN you got the CVS version.
