Ruby Forum Rails Engines > If Engines 1.2: Engines are dead why we still needed?

Hi,

From the article below "Engines 1.2: Engines are dead"
http://rails-engines.org/news/2007/01/03/engines-are-dead-long-live-engines/

if engines are dead why we still need it?
and how easy is it to convert current rails app using engine to become
plugins instead.

thank you in advance
