That worked fine for generating doc, but when I tried running tests for 
a particular sandbox library it failed because a header file which was 
only in the sandbox directory structure could not be found using a path 
such as 'boost/alibrary/alibrary.hpp' etc. This would be a valid path if 
the search for the header also began with the 'alibrary' directory but 
evidently it does not for whatever arcane Boost Build reason.

So it seems your technique is good for generating docs but not for 
running tests, where files from the sandbox library and from the boost 
trunk must both be found.
