hello all:
I have a fairly large code base that has a lot of modules and systems. 
The problem is that I have a main "engine" object that holds pointers to 
a lot of created modules and components. I'm trying to find a more 
dynamic way to do this, and I thought boost might be able to help. As a 
result, I have a couple of questions.

First, I do a lot of manual adding of features. For example, when I add 
a new command I have to add a engine->commands.AddCommand(new CMDFoo()); 
in an initialization method. Does boost provide some sort of mechenism 
for dynamically handling this?

I also plan on splitting up the main "engine" object and setting up the 
external modules as singletons. They act alone, but again I'd like to 
dynamically initialize these. Is there a way on entry to dynamically 
call specific singleton initialization methods, then at exit call their 
release methods?
I'd like to be able to set some sort of trait on these objects at 
compile-time that the runtime can use, or somehow generate the calls at 
compile-time.
Thanks in advance for any info,
