True, although there are several projects that use Avalon, as well as
a book in the works that uses it (for generic component oriented

All the generic subsubprojects like CLI/Event/Collections/etc.,
are in the process of being merged or superceded by the commons
counter parts.

-1.  The component is a component.  I don't like having too many
layers of wrappers.  It just slows things down.

We are working on this problem now.  We have two different
containers that are very powerful, yet easy to use.  We are
currently merging the concepts into one approach--which will
allow us to have a good, easy to use, container.

It's coming--but not as quickly as we all might like to see.
