Exception Hierarchy
Tools.h++ continues to use its own exception hierarchy, which is similar to the exception
hierarchy in the draft C++ Standard. We don't expect to change over until the standard
exception hierarchy is more widely available. You are free to use standard exceptions in
your application, but you must be prepared also to catch Tools.h++ exceptions when
making calls into the Tools.h++ library from within your try blocks.

Namespaces
Tools.h++ is not yet using or attempting to use namespaces specified by the current draft.
For now, we continue to use the RW prefix to distinguish our classes within the global
namespace. Of course, this does not preclude you from using namespaces in your own
application, if your compiler allows it.
