It's really easy. You just run it with two configuration files as inputs, and it gives a nice X display with different settings, and then settings that are only in one config or the other (resulting from different kernel versions or sub-config options). > Answering a dozen or so questions on the cmdline beats the poop out of > flopping around in menuconfig, or even worse, 2 instances of > menuconfig. > > What is really maddening is that I once knew how to do the stuff with > .config and `make oldconfig'.
