I replied to this off-list accidentally.

Yes, it figures. I had looked into libmandb, not libman. And had noticed 
this, so I never went any farther.

Makes sense to me.

Possibly. It would not be a bad idea for the database to updated when 
new packages are installed. However, it looks like to me that 
update-info-dir wipes and recreates the info files. It's rather time 
consuming to create the initial mandb database, and I'd be hesitant 
about doing that every time someone installs something. Perhaps I'm 
misunderstanding what you're suggesting.

I think this looks good. I'll see about producing another build in the 
morning using these patches. I'm away from the machine I've been 
building from at the moment.

Thanks, Yaakov. This has been a big help.
