 HISTORY
+  5.0.0
+    - added support for block caching. for example
+
+        - simple block caching:
+
+            class Filter 
+              attribute :process
+            end
+
+            (( filter = Filter.new )).process{|line| line.upcase}
+
+            lines.each do |line|
+              p filter.process.call(line)
+            end
+
+        - using block caching to delay block evaluation/class-factory:
+
+            module MigrationDSL
+              attribute :migration
+
+              def migration_class
+                model = self
+                Class.new(::ActiveRecord::Migration) do
+                  singleton_class =
+                    class << self
+                      self
+                    end
+                  singleton_class.module_eval{ attribute :model => model }
+                  singleton_class.module_eval &model.migration
+                end
+              end
+            end
+
+            class Table < ActiveRecord::Base
+              extend MigrationDSL
+            end
+
+            class Jobs < Table
+              migration do
+                def up
+                  create_table model.table_name, :primary_key => model.primary_key do |t|
+                    t.column 'rockin', :text
+                  end
+                end
+
+                def down
+                  create_table model.table_name
+                end
+              end
+            end
+
+            ...
+
+            JobsMigration = Jobs.migration_class
+
+    - cleaned up some warnings under 'ruby -d'
