Where to get hudson: https://hudson.dev.java.net/
If you have wget then you can do this:
/usr/local/bin/wget -N --no-check-certificate http://hudson.gotdns.com/latest/hudson.war

http://hudson.jboss.org/hudson/ is a real live Hudson site used by jboss.org

http://fisheye4.atlassian.com/browse/~raw,r=12517/hudson/trunk/hudson/pl... is not working for me because my cvs does not parse the huge string that I am using.

I logged into dev.java.net and review this program. It uses stringBuilder in a wasteful way. in arrayToString it creates a new stringBuilder for each line of the modules list. It should use append instead.

Also, since many CVS clients are old, the servers are old, it is prone to failure in many ways. It should not put the whole module list on one line. It should run cvs rtag for each module individually. Still, it still just use one stringBuilder object.

While Java is getting more advanced it is getting more complicated as well. Here are some links to products that may help.
