lsyncd dumping every file transferred to log

Question

I have lsyncd configured thus:

settings {
        logfile = "/var/log/lsyncd/lsyncd.log",
        statusFile = "/tmp/lsyncd.stat",
        statusInterval = 1,
        verbose = false,
}

sync {
        default.rsync,
        source    = '/xxxx/',
        target      = 'host:/xxxx/',
        delay     = 1,
}

When I invoke it as lsyncd -log Exec /etc/lsyncd/homedirs.lua the log file becomes extremely large extremely quickly, as every single file transferred is dumped to the log. How can I disable this? It's extremely bad design for something to be this verbose by default.
