Yes - works for me :-)

But to avoid providing BOOST or BOOST_ROOT environment variables, or parameter
--boost=i:\modular-boost

I also added

#~ Attempts to find the Boost source tree...
#~ --boost=i:\modular-boost may be needed.
local boost-src = [ if-has-file LICENSE_1_0.txt :
    [ MATCH --boost=(.*) : $(ARGV) ]
    $(BOOST)
    $(.boost-build-file:D)/../../modular-boost/ <<<<<<<<<<<<<<<<  new for modular-boost
    $(.boost-build-file:D)/../boost
    $(.boost-build-file:D)/../Trunk
    ] ;

I fear that I am not the only one who will need to make quite a few adjustments  (and also to MSVC
solutions/projects) as a result of modularization.

Thanks again.
