+Description
+===========
+
+Live example for [jsus](https://github.com/markiz/jsus) rack middleware.
+
+Installation
+============
+
+1. `bundle install`
+2. `rackup`
+3. Go to [http://localhost:4567/jsus/javasacripts/require/CKEditor](http://localhost:4567/jsus/javasacripts/require/CKEditor)
+and see the file being built
+4. Experiment with urls. E.g.: /jsus/javascripts/require/CKEditor:plugins.about.plugin+CKEditor:plugins.adobeair.plugin.js
+
+
+Things to notice
+================
+
+Caching is on by default, but sinatra lets middleware do its work before serving
+static files. This leads to regeneration per request. Use caching proxy, like
+kick-ass [nginx](http://nginx.org/) before your sinatra in order to succeed.
+
+
+License
+=======
+
+Application and libraries: UNLICENSE, same as jsus.
+
+CKEditor and other files: look in the respective sources.
