How often are the latest docs generated?

[Kim Haase]

The "Latest Alpha Manuals" on the Derby documentation page at 
http://db.apache.org/derby/manuals/index.html appear to have been 
generated on May 21.

Is there some reason why the docs are not being regenerated regularly? 
There have been some documentation commits since then, some of which 
have also been backported to 10.4 -- so that should be regenerated too.

Thanks,
Kim Haase
