yep, that's the idea. as for the init() method, you only need it if
your tool needs access to the initData for that scope (ServletContext
for application scope and ViewContext for request or session scope).
if your tool doesn't need access to any of those things, then it
doesn't need an init(Object) method.
of course, this is all with Tools 1.3 or Tools 1.4. with Tools 2,
things get even easier. :)
