OK, I've been confused on this for a while; somebody please set me  
straight.

WP 2+ already  includes a  /wp-content/cache directory. If I make it  
apache-writable, it gets populated and constantly updated with fresh  
cache files. No plugins or modifications necessary.

I've found references around the web to the fact that WP2 includes  
full Smarty caching, out of the box. So I've inferred that caching is  
fully present and working.

But I also  keep seeing references to WP-Cache 2, as if caching  were  
NOT already present in WP 2.

What's the real caching deal?

Thanks,
Scot
