The install docs are also in the nightly tarball build.
I spent much of yesterday and am spending much of today on preliminary work to roll out the beta tarball, so ye of little faith will be proved wrong before long. We really *will* have a beta, yes indeed!
I hope the news doesn't cause *too* many heart attacks! :)
It will probably be the end of the weekend before I actually release it, as I have other (client) work I also need to work on during the week.
But ... the wheels are finally turning and it will happen.
