Buildbot documentation

[MK-MacPorts at techno.ms]

This link shows a nice waterfall graph where you can see which tasks are running currently:

	http://build.macports.org/waterfall

The first column shows who submitted changes at which time. These changes will go into the next build as soon as the currently running one has finished.

Clicking on "build XXXX" reveals which ports are actually being built together in a certain build. The various stages of a build may give you important info if you have to debug something, i.e. compile/progress or compile/stdio.

Hmm, I don't know whether there is any detailed description somewhere on MacPorts' wiki, though. At least the Guide has not yet any info about it! Perhaps it's a good idea to add a little section about this tool. I'd be willing to arrange that if someone has valuable input to offer.
