This description was added 20 years ago [1]. It does not convey any
useful information except for a feeling of nostalgia.

External modules have traditionally used "grep" to check for
specific `CONFIG_` settings directly in .config. This usage is
broken. As introduced before, external modules should use
kbuild for building and can therefore use the same methods as
in-tree modules when testing for `CONFIG_` definitions.
