## howto create vendor bundle (upstream approach is not feasable)
# >> git clone https://gitlab.com/asus-linux/asusctl -b <version> /tmp/asusctl
# >> cd /tmp/asusctl && version=`git describe --tags | sed -E "s/v([0-9.]+)/\1/g"`
# >> mkdir -p .cargo && cargo vendor | head -n -1 > .cargo/config
# >> echo 'directory = "vendor"' >> .cargo/config
# >> mkdir -p asusctl-${version}/.cargo &&  mv vendor asusctl-${version}/vendor
# >> mv .cargo/config asusctl-${version}/.cargo
# >> tar -caf asusctl-${version}-vendor.tar.xz asusctl-${version}/vendor
# >> tar -caf asusctl-${version}-cargo_config.tar.xz asusctl-${version}/.cargo
