I've setup the hudson runs.
Internally (JBoss) they can be accessed here:
http://hudson.qa.jboss.com/hudson/job/Errai/
After
jboss.org sync they will publicly available
at
hudson.jboss.org.
This means from that point people can access latest stable
builds and documentation from that url.
I'll send around an email once the public hudson instance is in sync.
