Increase logging level with fop?

Hi Everyone,

I have a script that builds a DocBook. The script uses FOP 2.8. The
output of the script is cluttered with:

    Jun 30, 2023 4:28:00 PM org.apache.fop.events.LoggingEventListener
processEvent
    INFO: Rendered page #1.

I don't want INFO level. It creates too much noise. I only want
warning and error level. I want to know about problems.

I checked the manual, but I don't see a configuration for logging
levels [1] or changing the log level when running fop [2].

How do I invoke fop to increase the logging level?

Thanks in advance.
