   6# for building kernel modules, we use kernel build system using make, as
   7# with Linux. We have a skeleton BSDmakefile, which pulls many of its
   8# values from the environment. Each module only has a single source file
   9# right now, which allows us to simplify things. We pull in the sourcer
  10# files from the individual meson.build files, and then use a custom
  11# target to call make, passing in the values as env parameters.
