# You can reuse it in your Makefile:
# BUILD_FLAGS=$(shell ./get_ldflags.sh)
# your_target: your_target.go Makefile ${OTHER_DEP}
# 	go build -o $@ -ldflags "${BUILD_FLAGS} ${LDFLAGS}"

# you can add more flags here:
build_flags+=" -X 'main.GoBuildVersion=$(go version)' -X 'main.ByUser=${USER}'"

# the last command MUST display all build_flags
