# icecream-create-env - helper script to create icecc environments(mostly for cross-compiling)
#
# Copyright 1999-2020 Gentoo Authors
# Distributed under the terms of the GNU General Public License v2
#
# Please note, this script has been designed to work with Gentoo's crossdev, it may or may
# not work with cross-toolchains that were build differently.
#
#
# Usage: "./icecream-create-env" creates a native environment(similar to icecc --build-native)
# "./icecream-create-env prefix" creates a cross-compile environment using the cross-toolchain created by crossdev
# Example:
# "emerge crossdev && crossdev -t sparc-unknown-linux-gnu && icecream-create-env sparc-unknown-linux"
