+marshaled_attributes
+====================
+
+A simple plugin for saving marshaled objects using ActiveRecord.
+
+Instalation
+-----------
+
+Install the plugin with `script/plugin install git://github.com/fnando/marshaled_attributes.git`
+
+Usage
+=====
+
+Considering the following schema:
+
+	create_table :pages do |t|
+	  t.string 	:name
+	  t.text 	:body
+	  t.binary 	:meta
+	end
+
+1) Add the method call `marshaled_attributes` to your model.
+
+	class Page < ActiveRecord::Base
+	  marshaled_attributes :meta
+	end
+
+	@page = Page.new # => do not mass-assign the marshaled attributes.
+	@page.meta = {:last_comment_id => 100}
+
+IMPORTANT: Remember NOT to mass-assign the attributes you want to be marshaled.
