+The biggest user-visible change is that the former modes of operation
+have been replaced by subcommands. For example, the former -R option
+to start dss in "run" mode corresponds to the "run" subcommand of
+version 1.0.0. Each subcommand has its own set of options. Global
+options and options for subcommands are split with the usual "--"
+separator. For example, to specify the global --loglevel option and
+the run-specific --daemon option, use dss --loglevel 2 -- run --daemon.
