.PHONY: all prepare deps build

# This Makefile is a simple example that demonstrates usual steps to build a binary that can be run in the same
# architecture that was compiled in. The "ldflags" in the build assure that any needed dependency is included in the
# binary and no external dependencies are needed to run the service.
