Makefile

# Makefile for building and testing `boring`
# Usage:
#   make / make build    - Build the binary
#   make build-grid      - Cross-compile for all OS/ARCH
#   make test            - Run tests
#   make cover           - Run tests with coverage
#   make cover-html      - Generate interactive HTML report
