I've been hearing a lot about erubis: http://www.kuwata-lab.com/erubis/
Especially about how much faster it is than straight ERB.
In their Ruby on Rails support docs: http://www.kuwata-lab.com/erubis/users-guide.05.html#topics-rails
They state that with a few added lines to your environment.rb it will
replace ERB completely.
I'm wondering if anyone has done this in an existing application and
if there are any existing ERB area's this might break. I'd also like
to hear anyone's experience with Erubis in general. Thanks.
