+module Rack
+
+  # The Rack::Static middleware intercepts requests for static files
+  # (javascript files, images, stylesheets, etc) based on the url prefixes
+  # passed in the options, and serves them using a Rack::File object. This
+  # allows a Rack stack to serve both static and dynamic content.
+  #
+  # Examples:
+  #     use Rack::Static, :urls => ["/media"]
+  #     will serve all requests beginning with /media from the "media" folder
+  #     located in the current directory (ie media/*).
+  #
+  #     use Rack::Static, :urls => ["/css", "/images"], :root => "public"
+  #     will serve all requests beginning with /css or /images from the folder
+  #     "public" in the current directory (ie public/css/* and public/images/*)
