I have a family of classes that all descend from a single class, call it class  
A.  As soon as possible after application launch, I need to build a list of the  
names of these classes, so that the list is available to the entire application  
before anything really happens.  For example, I want to wind up with a list of  
strings that looks like this:

	"A"  "B"  "C"  "D"  "E"

Such a list could come from any number of different class hierarchies.  Here are  
three examples that would produce the above list (if you are reading this in a  
proportional font, you may want to copy it to something mono-spaced so things  
line up properly):

   Object -- ... -- A +- B -- C
                      |
                      +- D -- E

   Object -- ... -- A -- B -- C +- D
                                |
                                +- E

   Object -- ... -- A -- D +- E
                           |
                           +- C -- B

It is not important that the list be sorted (that's easy enough to do once I  
have a raw list).  I am guaranteed to know that class A exists and is linked  
into the app, but other than that I will know nothing about A or its subclasses.   
For example, I will not know if there are any subclasses of A, nor the names of  
the subclasses of A if they do exist, nor the structure of the inheritance tree  
above or below A, nor if any instances of A or any of its subclasses exist or  
will exist during the run of the app.

Any and all ideas will be greatly appreciated.

Thanx,
Michael
