man.output.quietly boolean
man.output.quietly Suppress filename messages emitted when generating output?

## Description

If zero (the default), for each man-page file created, a message with the name of the file is emitted. If non-zero, the files are output "quietly" -- that is, the filename messages are suppressed.

If you are processing a large amount of refentry content, you may be able to speed up processing significantly by setting a non-zero value for man.output.quietly.
