        # for now this is kind of ad-hoc:
        #
        # 1. The default flow command is check with the --all flag. This flag
        # can be overridden here with the line "all: false". Anything besides
        # "false" is ignored, and the setting itself is ignored if a command
        # besides check is run.
        #
        # 2. The default flow command can be overridden here by supplying the
        # entire command on a line that begins with "cmd:". (Note: for writing
        # incremental tests, use the option below). A line beginning with
        # "stdin:" can additionally supply arguments to pass to the command via
        # standard input. We start the server before running the command and
        # stop the server after we get a result.
        #
        # 3. Integration tests that interleave flow commands with file system
        # commands (for testing incremental checks, e.g.) are written by
        # supplying the name of a shell script on a line that begins with
        # "shell:". The shell script is passed the location of the flow binary
        # as argument ($1). We start the server before running the script and
        # stop the server after the script exits.
