MacPorts 2.3.0-beta1 now available for testing

["René J.V. Bertin"]

Just a though/suggestion, if still in time:

would it be possible to add an option to the port command allowing to override the number of build jobs configured in macports.conf ?
Most of the time I let MacPorts builds grind away in the background, and so allow only 2 out of my 4 (virtual) cores, but there are times I'd like to go higher without having to edit the configuration file ...
