Make sure the unique parts of this package are at least basically documented. Including:

• Configuration/extension mechanisms
• Use of Chameleon and full ZPT/TAL/TALES
• Speed optimizations (are the parallel image renderers here?)
• Other? What am I forgetting?

[jamadden]

are the parallel image renderers here?

No, they aren't. They probably should be, though, or we should open up the package that includes them (nti.contentrendering).
