# This is a utility to remove the Bazel cache after using Planter
#
# After using planter the cache contents are correctly owned by the host user,
# but some files are not writable so we make them writable and then delete
# the cache dir rather than the normal `bazel clean`.
# NOTE: this is a rough approximation of `bazel clean --expunge`
