Hi everyone!

Douglas,

By overview of O3-framework you're saying that

> Renamed all of your modules so that that conform to theBlackBox
> subsystem standard. Hence I now have
>O3App...
> O3Bb...
> O3Base...
> O3Host...
> O3Std...

> by doing that there need only be a single Code directory under O3

First of all, we need to define subsystem:

> For the BlackBox Component Builder, it is a convention that collections
> of related components, called subsystems, are placed into separate

Keep all constituents of a component in one place.
> (quoted from Design Practices)

Here we can see that subsystem is collection of components, not modules.
Actually saying, if there were only modules, it would be forbidden to use
any dependencies in your own subsytem.

Thus we have "components", it takes us to a typical use-case of
wrapping abstractions in single module of SubsystemA,
that wraps a bunch of modules in SubsystemB.
For example, lets take a look to a pair of Std+Host subsytem in BlackBox.
Is there any reason to put them in a single directory?

So, if you will look up for dependencies of O3-framework (not
O3-subsystem, obviously)
you will find several different layers of abstraction, that could be used
distinctly,
as well as in scope with other O3xxx-subsystems.

Best regards, Peter Cushnir, Russia, Yaroslavl.
P.S. Sorry for my poor English :)
