 #
 # Option file for FreeBSD /usr/src builds.
 #
 # Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
 # and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
 # with sensible (usually) defaults.
 #
 # Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
 # are applicable for that Makefile (typically there are none, but sometimes there
 # are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
 # to omit from that make.
 #
 # Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
 # variable.
 #
 # Makefiles may also assume that this file is included by src.opts.mk should it
 # need variables defined there prior to the end of the Makefile where
 # bsd.{subdir,lib.bin}.mk is traditionally included.
 #
 # The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
 # should be added. Old instances should be removed since they were just to
 # bridge the gap between FreeBSD 4 and FreeBSD 5.
 #
 # Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
 # exception is made for _WITHOUT_SRCONF which turns off this mechanism
 # completely inside bsd.*.mk files).
 #

 .include <bsd.own.mk>
 
 #
 # Define MK_* variables (which are either "yes" or "no") for users
 # to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the
 # make(1) environment.
 # These should be tested with `== "no"' or `!= "no"' in makefiles.
 # The NO_* variables should only be set by makefiles for variables
 # that haven't been converted over.
 #
 
 # These options are used by the src builds. Those listed in
 # __DEFAULT_YES_OPTIONS default to 'yes' and will build unless turned
 # off.  __DEFAULT_NO_OPTIONS will default to 'no' and won't build
 # unless turned on. Any options listed in 'BROKEN_OPTIONS' will be
 # hard-wired to 'no'.  "Broken" here means not working or
 # not-appropriate and/or not supported. It doesn't imply something is
 # wrong with the code. There's not a single good word for this, so
 # BROKEN was selected as the least imperfect one considered at the
 # time. Options are added to BROKEN_OPTIONS list on a per-arch basis.
 # At this time, there's no provision for mutually incompatible options.
