      This will make use of the new headers_install rule in recent kernels.

      This is most probably what you want to use.

    help

      M. Mazur used to maintain a tree of sanitised headers, but it is now

      obsoleted by the headers_install rule (above), and has not seen eny

      update since 2.6.12

    help

      This will simply copy the kernel headers to the toolchain.

      You do NOT want this. It's badly broken because it leaks kernel internals

      to userspace.

      If you have some kernel headers lying around, you can enter the path

      See extra versions (kernel with 4 numbers, eg 2.6.19.1).

      If you say 'no', you'll only see sub-level, 3-digit versions.

      If you say 'yes', you'll see far more versions!

      It is recommended that you say 'no', unless you _*know*_

      that an extra version fixes a headers bug.
