[boost] docs on new build system?

Subject: [boost] docs on new build system?

I am testing 1_49_0_beta1.  I see my usual build failed, saying 'warning: 
mismatched versions of Boost.Build engine and core'.  Taking a wild guess, tried

cd tools/build/v2

sh ./bootstrap.sh
sudo ./b2 install --prefix=/usr/local

I see I now have a new bjam, and something called 'b2'.

Should I be reading some new docs on how to use this stuff?  Are there some 
docs?

My old build procedure:

bjam -sHAVE_ICU=1 -sEXPAT_INCLUDE=/usr -sEXPAT_LIBPATH=/usr/lib64 --
layout=tagged threading=single,multi stage 

Seems to be proceeding normally (so far)
