Hi Pierre,

That’s correct: in this patch set parameters are per-package, and I
think it’s easier to start simple, but we could implement what you
describe without too much hassle I think.

For example, you’d type ‘--with-parameters=x11=false’, and that’d be
applied to all the packages that have an ‘x11’ parameter.

Ludo’.
