I\'ve followed the very thorough instructions below to add sprockets/asset pipeline to a legacy Rails 2.3.18 application I\'m working on:

@joris provided good insight, but I had already figured it out by the time you replied!
Inside assets.rake#internal_precompile
, change the last line to:
manifest.compile [ Proc.new { |path| !%w(.js .css).include?(File.extname(path)) }, /application.(css|js)$/ ]
Found this answer a little ways down on this page: http://guides.rubyonrails.org/asset_pipeline.html#precompiling-assets
