# Frozen Python from cmods extension repos, plus the CircuitPython upstream
# freeze for the active port/board/variant.
#
# ``build_cp.sh`` sets ``FROZEN_MANIFEST_UPSTREAM`` to the freeze CircuitPython
# would use: a unix variant/port manifest, or a generated ``BUILD/manifest.py``
# when ``FROZEN_MPY_DIRS`` is nonempty. Upstream may be empty for boards with
# no generated freeze.
#
# Optional local overrides: ``manifest-user.py`` (gitignored). Use ``package()``
# to freeze a tree; paths are relative to the current (workspace) directory.
#
# Child ``*/manifest.py`` inclusion (no hard-coded repo names): include when the
# sibling has ``apply_cp_patches.sh``, or lacks ``micropython.mk`` (skips
# MicroPython-only trees that would double-freeze shared helpers).
