# This file should work for both amd64 and arm64 builds. Because segway did not release some source code we must copy some binaries for the specific architectures.
# That is why we must use some conditional statements to copy over the correct files during build process.
# Variable TARGETPLATFORM should be auomatically created during build process by docker.
