Missing manpage for main.conf

I was looking for a way to disable BlueZ logging (Ubuntu machine), and
came across this, in the bluetoothd manpage:

'bluetoothd itself does not accept many command-line options, as most of
its configuration is done in the /etc/bluetooth/main.conf file, which
has its own man page.'

That doesn't appear to be true. I can't find any trace in any distro, or
in the source. I've found a bug filed here and there against the lack of
manpage, but no manpage.

There's definitely logging going on by default:

localhost ~ [0]# lsof -n 2> /dev/null | grep blue | grep log
rsyslogd   804          syslog    2w      REG               0,21    
2027       8482 /var/log/bluetoothd.log
rs:main    804  813     syslog    2w      REG               0,21    
2027       8482 /var/log/bluetoothd.log
rsyslogd   804  814     syslog    2w      REG               0,21    
2027       8482 /var/log/bluetoothd.log
rsyslogd   804  815     syslog    2w      REG               0,21    
2027       8482 /var/log/bluetoothd.log

Unfortunately, there's no hint anywhere what's causing bluetoothd to
log, or how to stop it.
