copperhead

#!/usr/bin/env bash
# Fetch the optional external engines copperhead's placers and routers wrap
# (ADR 0008) into vendor/tools/ (git-ignored): a Temurin JRE 25 and the
# Freerouting jar, and a Python venv with kicad-tools. Nothing is bundled with
# copperhead; the wrappers discover these paths (or COPPERHEAD_* overrides) at
# runtime. These are copperhead's engine toolchain, not benchmark data: the
# benchmark that exercises them lives in the copperbench repository.
#
# Usage: scripts/tools.sh [jre|freerouting|kicad-tools|pyplacer|all]   (default: all)
