#
#
# The following variables contain defaults for sets.subr functions and callers:
# setsdir path to src/distrib/sets
# nlists list of base sets
# xlists list of x11 sets
# obsolete controls if obsolete files are selected instead
# module if != "no", enable MODULE sets
# shlib shared library format (a.out, elf, or "")
# stlib static library format (a.out, elf)
#
# The following <bsd.own.mk> variables are exported to the environment:
# MACHINE
# MACHINE_ARCH
# MACHINE_CPU
# HAVE_ACPI
# HAVE_BINUTILS
# HAVE_GCC
# HAVE_GDB
# HAVE_NVMM
# HAVE_OPENSSL
# HAVE_SSP
# HAVE_UEFI
# TOOLCHAIN_MISSING
# OBJECT_FMT
# as well as:
#
#
# The following variables refer to tools that are used when building sets:
#

# If printf is a shell builtin command, then we can
# implement cheaper versions of basename and dirname
# that do not involve any fork/exec overhead.
# If printf is not builtin, approximate it using echo,
# and hope there are no weird file names that cause
# some versions of echo to do the wrong thing.
# (Converting to this version of dirname speeded up the
# syspkgdeps script by an order of magnitude, from 68
# seconds to 6.3 seconds on one particular host.)
#
# Note that naive approximations for dirname
# using ${foo%/*} do not do the right thing in cases
# where the result should be "/" or ".".

#
# The third field is an optional comma separated list of keywords to

# make -f mkvars.mk mkvarsyesno
#
# These MK<NAME> variables can be used as selectors in the sets as <name>.
#
# The following extra keywords are also available, listed by:
#
# make -f mkvars.mk mkextravars
#
# These are:
# 1. The HAVE_<name>:
# ssp ${HAVE_SSP} != no
# libgcc_eh ${HAVE_LIBGCC_EH} != no
# acpi ${HAVE_ACPI} != no
# binutils=<n> <n> = value of ${HAVE_BINUTILS}
# gcc=<n> <n> = value of ${HAVE_GCC}
# gdb=<n> <n> = value of ${HAVE_GDB}
# mesa_ver=<n> <n> = value of ${HAVE_MESA_VER}
# nvmm ${HAVE_NVMM} != no
# openssl=<n> <n> = value of ${HAVE_OPENSSL}
# uefi ${HAVE_UEFI} != no
# xorg_server_ver=<n> <n> = value of ${HAVE_XORG_SERVER_VER}
# xorg_glamor ${HAVE_XORG_GLAMOR} != no
#
# 2. The USE_<name>:
# use_inet6 ${USE_INET6} != no
# use_kerberos ${USE_KERBEROS} != no
# use_ldap ${USE_LDAP} != no
# use_yp ${USE_YP} != no
#
# 3. Finally:

#
# solaris ${MKDTRACE} != no or ${MKZFS} != no or ${MKCTF} != no
