Dear maintainer,
after reading the make manual on inclusion of other make files, I was still left with a question.
If a variable is set in a parent makefile, and a child makefile is included, is the variable also set in the child makefile. And the other way around, when a variable is set in the child, is it also still usable in the parent, or does it fall out of scope.
I have figured this out with a simple example, but it would be useful to have in the manual as well, I think. :)
