Still, I couldn't resist to play with your version and come up with this:
'Apache Forrest is a standards-based framework for Single Source Publishing, transforming different input to unified output in formats like HTML and PDF. Its modular and extensible architecture is based on Apache Cocoon and emphasizes the strict separation of presentation and content. Forrest can generated static documents, run on an application server or be deployed by an automated publishing application.'
Actually, I really like the sound of this. It seems to flow much better.
