# Build AmiPart using the Bebbo amiga-gcc toolchain via Docker.

# Usage:
#   ./docker.sh                # build (forwards to: make TOOLCHAIN=bebbo)
#   ./docker.sh clean          # clean
#   ./docker.sh <make-args>    # any extra args are forwarded to make
#
# Environment overrides:
#   IMAGE=...   docker image (default: trixitron/m68k-amigaos-gcc)
#   AMIGA=...   toolchain path inside the container (default: /opt/amiga)

# handles host-user ownership mapping automatically. On Linux, the bind-mount
# preserves container ownership, so chown build artifacts back at the end.
