# Go parameters

# CGO_ENABLED=0   -> Disable interoperate with C libraries -> speed up build time! Enable it, if dependencies use C libraries!
# GOOS=linux      -> compile to linux because scratch docker file is linux
# GOARCH=amd64    -> because, hmm, everthing works fine with 64 bit :)
# -a              -> force rebuilding of packages that are already up-to-date.
# -o gpio-test-x  -> force to build an executable gpio-test-x file (instead of default https://golang.org/cmd/go/#hdr-Compile_packages_and_dependencies)
