One of the major pain points of Review Board has been its installation methods. Users had to do a lot to get Review Board up and running initially. We've finally addressed this with new Python Egg packaging and a site installation wizard.
The major parts of installation basically boils down to two commands:
$ sudo easy_install ReviewBoard $ sudo rb-site install /var/www/sitename
While upgrading is now:
$ sudo easy_install --upgrade ReviewBoard $ sudo rb-site upgrade /var/www/sitename
