-# The top-level west manifest file for upstream bacnet-stack.
-
-# This top-level west manifest file intentionally provides only the
-# minimal configuration necessary for a successful 'west init', in
-# expectation that multiple manifests will exist within one branch
-# of this repository.  Once 'west init' has completed, west may be
-# configured to use alternate manfiests with the following command:
-#
-#   west config manifest.path <manifest_dir_from_topdir>
-#
-#     e.g. west config manifest.path bacnet-stack/zephyr/manifests/zp/zephyr
-
-# NOTE: Since the schema requires at least one project name,
-# the mapping of this repository must be described as a project
-# rather than under the 'self' key.
