#
# This file is included by bsd.prefs.mk only if EMUL_PLATFORMS is defined
# and non-empty.
#
# User-settable variables:
#
# EMUL_TYPE.${EMUL_OPSYS}
# Specifies the "type" or "variant" of ${EMUL_OPSYS} to use, e.g.
# ${EMUL_TYPE.linux} == "suse".
#
# EMUL_PLATFORM
# Specifies the platform to emulate, and is of the form
# ${EMUL_OPSYS}-${EMUL_ARCH}, e.g. linux-i386. By default
# this is the best-matching platform listed in EMUL_PLATFORMS
# chosen based on EMUL_PREFER.
#
# EMUL_PREFER
# The list of platforms to try to emulate in order of preference.
# By default, only try to emulate the native platform. See the
# _EMUL_PREFER.* table below for additional preferences for various
# platforms.
#
# Package-settable variables:
#
# EMUL_PLATFORMS
# List of "${EMUL_OPSYS}-${EMUL_ARCH}" binary emulations supported
# by the package. This should be set prior to the inclusion of
# bsd.prefs.mk.
#
# Default value: undefined
#
# Variables defined by this file:
#
# EMUL_ARCH
# The machine architecture being emulated, e.g. i386. If the
# package isn't supported on this machine, then its value is
# "none".
#
# EMUL_OPSYS
# The operating system being emulated, e.g. linux. If the
# package isn't supported on this machine, then its value is
# "none".
#
# EMUL_IS_NATIVE
# Whether or not the operating system being emulated matches the
# native operating system. It is either defined or undefined.
