In case of libraries inside Boost trunk, the variable that gives root location
inside Jamfiles is called BOOST_ROOT. I suppose it's reasonable to make
the variable be called the same inside sandbox. In fact, it appears to be
already the case. When I get myself a sandbox checkout, go to
'example' subdirectory and go:

        bjam --boost=/home/ghost/Work/Boost/boost-svn

I see that BOOST_ROOT is indeed set to boost root.

Therefore, what questions remain? 

1. Do you want to be able to set an environment variable, say BOOST_ROOT,
and avoid that --boost option?

2. Do you want to be able to detect where Boost root is, without either option
or an environment variable (this is not possible in all cases).

3. Something else?

Thanks,
Volodya
