It's a bit easier to read, and follows the same patterns as ant ( well,
almost :-). That should mean less things to learn.

Well, the whole thing about adding new tomcat modules is very similar
with adding new ant tasks, just replace <taskdef> with <module>. The big
difference is that instead of one method used by ant ( execute ), tomcat
has about 20 places a module can hook into.

Well, the other "fun" part is that we do introspection on each module to
detect what methods it overrides. So you can have as many "config" modules
as you want, each chain has only the modules that matter.

Of course, you can remove the module from the chains in addInterceptor
( just get the Hooks object and removed it ), or you can override
registerHooks and not have it registered in any hook chain.
