+# needed to release Synapse. This is useful on systems like macOS where such scripts are
+# not easily accessible.

+#   docker run --rm -v $PWD:/synapse ubuntu:latest /synapse/scripts-dev/docker_update_debian_changelog.sh VERSION
+#
+# The image can be replaced by any other Debian-based image (as long as the `devscripts`
+# package exists in the default repository).
+# `VERSION` is the version of Synapse being released without the leading "v" (e.g. 1.42.0).
+
+# Check if a version was provided.
