+# with Linux. We have a skeleton BSDmakefile, which pulls many of its
+# values from the environment. Each module only has a single source file
+# right now, which allows us to simplify things. We pull in the sourcer
+# files from the individual meson.build files, and then use a custom
+# target to call make, passing in the values as env parameters.
