# This is the Coder Makefile. The build directory for most tasks is `build/`.
#
# These are the targets you're probably looking for:
# - clean
# - build-fat: builds all "fat" binaries for all architectures
# - build-slim: builds all "slim" binaries (no frontend or slim binaries
#   embedded) for all architectures
# - release: simulate a release (mostly, does not push images)
# - build/coder(-slim)?_${os}_${arch}(.exe)?: build a single fat binary
# - build/coder_${os}_${arch}.(zip|tar.gz): build a release archive
# - build/coder_linux_${arch}.(apk|deb|rpm): build a release Linux package
# - build/coder_${version}_linux_${arch}.tag: build a release Linux Docker image
# - build/coder_helm.tgz: build a release Helm chart
