but e.g. the includes in the header of test1 refer to "../config.h"
which seems incompatible with the directory structure you use in boost
IMO : There is no subdirectory in the directory where config.h is
located ? (I figure you use some other file-structure layout to compile
Anyway, I'm very interested in using uBlas and could also produce
Jamfiles if you like to build the tests automatically (I would suggest
moving the ublas on the main branch in that case however as otherwise
synchronising with the latest Jam developments might be difficult)

What is the relation to MTL3.0 development in Boost ?

I would like to look at making specialisations for using Blas internally
(too have the most performant alternative as long as the C++
implementation is at par with Blas) if it does not collide with the
roadmap you have in mind.
