# $NetBSD: emulator.mk,v 1.11 2009/04/04 12:16:45 rillig Exp $
#
# This file is included by bsd.pkg.mk.
#
# Package-settable variables:
#
# EMUL_REQD
# List of required versions for different emulation types, e.g
# suse>=10.0, netbsd>=1.2, etc.
#
# EMUL_MODULES.${EMUL_OPSYS}
# List of modules of ${EMUL_OPSYS} that are used by the package.
#
# Default value: undefined
#
# EMUL_PKG_FMT
# Binary emulation packaging format requested by the package.
# Possible values: any format listed in ${_EMUL_PKG_FMTS}.
#
# Default value: plain
#
# Variables defined by this file:
#
# EMUL_DISTRO
# The distribution of the emulated operating system being used,
# e.g. native-linux, suse-10.0, etc. If the package isn't
# supported on this machine, then its value is "none".
#
# EMULDIR
# Convenience variable that expands to ${PREFIX}/${EMULSUBDIR}
#
# EMULSUBDIR
# Path relative to ${PREFIX} where the files and directories
# are located, e.g. emul/linux.
#
# OPSYS_EMULDIR
# Path through which the platform expects to find a "chroot"
# installation of the files and directories, e.g. /emul/linux.
#
# EMULSUBDIRSLASH
# Expands to either ${EMULSUBDIR}/lib or just lib depending on
# whether EMULSUBDIR is empty or not. It is meant to be used
# in PLISTs and files where one wants to avoid "//" artifacts,
# e.g., ${EMULSUBDIRSLASH}lib.
#
# Public targets:
#
# emul-fetch
# This is a public target that fetches the distfiles for all
# supported EMUL_PLATFORMs.
#
# emul-distinfo
# This is a public target that generates a new distinfo file
# that contains checksums for all supported EMUL_PLATFORMs.
# This target should be run after the successful completion
# of the ``emul-fetch'' target.
#
# Keywords: emulator, emulation, emul
