5 # Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
6 # and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
7 # with sensible (usually) defaults.
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.
14 # Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
17 # Makefiles may also assume that this file is included by src.opts.mk should it
18 # need variables defined there prior to the end of the Makefile where
19 # bsd.{subdir,lib.bin}.mk is traditionally included.
21 # The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
22 # should be added. Old instances should be removed since they were just to
23 # bridge the gap between FreeBSD 4 and FreeBSD 5.
25 # Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
26 # exception is made for _WITHOUT_SRCONF which turns off this mechanism
27 # completely inside bsd.*.mk files).

40 # The NO_* variables should only be set by makefiles for variables
41 # that haven't been converted over.
