I do not care about the rest, It's "I *do NOT know* what the rest do". I cannot document something that I have no knowledge of, can I? So as a reasonable start I added only those that I'm familiar with (and I have explicitly stated that in previous emails), and I disagree with the "bad attitude" label. > This should be all or nothing. > > I do not think all the env variables can be summarized > to fit in help. So the rational for that was that people run "make help" and find out about new build targets, for instance, but there is no way for people to find out about new Kconfig features (and yes, we are talking "new features" here) that are controlled by env variables. We need to do something about it, don't you agree?
