building html docs

I find myself wanting to investigate the accumulators library in a bad way.

I find its only in the trunk - ok.
The documentaiton is written in quickbook - ok
The generated html isn't in the trunk - ok
so to build the html I run

bjam

from the libs/accumlators/doc directory and I get the folllowing.

what do I have to do to look at the html version of the documentation
for this library?
