Are docs intentionally included in war?

[David Jencks]

When I build trunk, unpack roller-weblogger.war, and run du -k -d3 .  
| sort -n -r it looks to me as if there is a lot (~ 4.8 mB) of  
documentation that is not readily accessible from roller in

roller-ui/docs
Is this intentional?  Did I miss a link to this somewhere?  Am I  
misinterpreting du's output and it's really a lot smaller?

thanks
