`MLton.Syslog` is a complete interface to the system logging facilities. See `man 3 syslog` for more details.

- `closelog ()`
  closes the connection to the system logger.

- `log (l, s)`
  logs message `s` at a loglevel `l`.

- `openlog (name, flags, facility)`
  opens a connection to the system logger. `name` will be prefixed to each message, and is typically set to the program name.
