If some of them can contain only a single library, you can declare them in 
site-config.jam/user-config.jam

If many of them are multu-library, then creaing 10 .jam files may be 
inconvenient. In that case you can create some rule which will implement 
either of two approaches I've outlined in the last email. Users will be able 
to call that rule from user-config.jam, for example:

use-prebuilt-lib-set ublas : a b c d e ;

The implementation of 'use-prebuilt-lib-set' can be placed in a module which 
will be loaded in user-config.jam with "import".

You can add any directory to BOOST_BUILD_PATH (either in environment or in 
boost-build.jam) and place your extensions there.
