+## JBundle (in progress)
+
+Define a set of javascript files to bundle and minify
+
+    JBundle.config do
+      version '1.6.1'
+
+      src_dir File.dirname(__FILE__) + '/src'
+
+      bundle 'foo.js' do
+        file 'file1.js'
+        file 'file2.js'
+      end
+
+      bundle 'foo2.js' do
+        file 'file3.js'
+        file 'file4.js'
+      end
+
+      file 'file4.js'
+
+      file 'text.txt'
+      
+      # Filters can be use for string substitution
+      filter do |src, config|
+        src.gsub!(/<VERSION>/, config.version)
+      end
+
+    end
+    
+Then write them to a directory
+
+    JBundle.write_to './dist'
+    
+This will write the following files:
+
+    'dist/1.6.1/foo.js'
+    'dist/1.6.1/foo.min.js'
+    'dist/1.6.1/foo2.js'
+    'dist/1.6.1/foo2.min.js'
+    'dist/1.6.1/file4.js'
+    'dist/1.6.1/file4.min.js'
+    'dist/1.6.1/text.txt'
+    
+    'dist/1.6/foo.js'
+    'dist/1.6/foo.min.js'
+    'dist/1.6/foo2.js'
+    'dist/1.6/foo2.min.js'
+    'dist/1.6/file4.js'
+    'dist/1.6/file4.min.js'
+    'dist/1.6/text.txt'
+    
+Or you can build a single bundle/file dinamically (ie. for testing)
+
+    JBundle.build('foo.js').src
+    
+Or
+
+    JBundle.build('foo.js').min
+    
+All defined filters will run on the src for all these cases.
