9 # Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
10 # are applicable for that Makefile (typically there are none, but sometimes there
11 # are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
12 # to omit from that make.

18 # need variables defined there prior to the end of the Makefile where
19 # bsd.{subdir,lib.bin}.mk is traditionally included.

22 # should be added. Old instances should be removed since they were just to
23 # bridge the gap between FreeBSD 4 and FreeBSD 5.
