+note * This build file is in the Make Abstract Machine (MAM) language. It was
+note * first generated by nmake, but in the ksh 93u+m distribution we maintain
+note * it manually because nmake had too many problems to keep using. The
+note * Mamfiles are processed by mamake (src/cmd/INIT/mamake.c); we added
+note * indentation to improve readability. The language is documented in
+note * src/cmd/INIT/README-mamake.md.
