# rcvd - build/install entry points for the single Go binary.
#
# `make build` is the canonical host-arch production recipe (static, -trimpath, stripped,
# build-stamped) - see the `build:` target below. The cross-compile targets delegate to the
# per-target scripts in scripts/ (which set GOOS/GOARCH but use the same flags).
#
#   make            # build a native binary           → ./rcvd
#   make build      # same
#   make build-linux-amd64  # Linux x86-64            → ./rcvd-amd64
#   make build-linux-arm64  # Linux aarch64           → ./rcvd-arm64
#   make build-mac-amd64    # macOS Intel (x86-64)    → ./rcvd-macos-amd64  (native or cross)
#   make build-mac-arm64    # macOS Apple Silicon     → ./rcvd-macos-arm64
#   make man        # render man/rcvd.1 from man/rcvd.1.md (go-md2man)
#   make test       # go test ./...
#   make install    # install binary + man page (PREFIX=/usr/local, needs sudo)
#   make uninstall  # remove installed binary + man page
#   make clean      # remove built artifacts
#
# Install paths follow the GNU convention and are overridable, e.g. a non-root user install:
#   make install PREFIX=$HOME/.local
