[Boost-build] Features and passing arguments to project

Hi,

I'm trying to create a project that should be customizable in some ways.
It is divided in three layers:
1. The libray shell, IOW the interface that interacts with the library client.
2. The drivers: the lower level libraries, that interact with
platform-specific code.
3. The manager. That is: static_manager or dynamic_manager that allows
compiling the entire library using one (static) or more (dynamic)
drivers. Allowing the client to choose between more dynamically
behavior or faster implementation.

I tried using features to accomodate this scenario but I stumbled on
the inspection of free features.

I would like to allow the user to specify one or more drivers, but I
can't see how.

For the choosing between static or dynamic managers I used propagated
features and alternatives. But is there an alternative to specify open
options by the user? These options would become dependencies and/or
modify the depedencies of other sub-projects.

Does anybody know how can I accomplish this?

Thanks,
