You are correct that's a way to do it. But I'm looking for a solution that
would be a bit more automatic. Like the user downloads the lib source code
and adds the location to the user-config.jam. Boost build will take it from
here.

I prefer the user to add the symbols inside user-config.jam. Of course a
template will be provided by the documentation.

What do you think?

But I'm a little afraid the time to implement all of my wish list will be
too long and possibly too steep. Since I'm a complete noob to boost build I
have to rely on people like Steven. And I'm sure they have better things to
do...
