.rcss files in public/stylesheets do not get rendered to .css files  
using Rails 3.0.0. What am I missing or doing wrong?

I never heard of RCSS before, and all the references are pretty old. I  
doubt that it works with Rails 3…have you looked at Sass?

Thanks Martin, we may have to go that way.

Rcss works in Rails 2.3.5 and, since I can find no deprecation  
warnings/announcements, I had hoped it would still work in 3.x. Oh  
well, looks like upgrading will take longer than expected.

Regards,
