-# ## What this script does
+# See the GNU Affero General Public License for more details:
+# <https://www.gnu.org/licenses/agpl-3.0.html>.
 #
-# This script spawns multiple workers, whilst only going through the code loading
-# process once. The net effect is that start-up time for a swarm of workers is
-# reduced, particularly in CPU-constrained environments.
+# Originally licensed under the Apache License, Version 2.0:
+# <http://www.apache.org/licenses/LICENSE-2.0>.
 #
-# Before the workers are spawned, the database is prepared in order to avoid the
-# workers racing.
+# [This file includes modifications made by New Vector Limited]
 #
-# ## Stability
-#
-# This script is only intended for use within the Synapse images for the
-# Complement test suite.
-# There are currently no stability guarantees whatsoever; especially not about:
-# - whether it will continue to exist in future versions;
-# - the format of its command-line arguments; or
-# - any details about its behaviour or principles of operation.
-#
-# ## Usage
-#
-# The first argument should be the path to the database configuration, used to
-# set up the database. The rest of the arguments are used as follows:
-# Each worker is specified as an argument group (each argument group is
-# separated by '--').
-# The first argument in each argument group is the Python module name of the application
-# to start. Further arguments are then passed to that module as-is.
-#
-# ## Example
-#
-#   python -m synapse.app.complement_fork_starter path_to_db_config.yaml \
-#     synapse.app.homeserver [args..] -- \
-#     synapse.app.generic_worker [args..] -- \
-#   ...
-#     synapse.app.generic_worker [args..]
