+module ActiveRecord
+  # Allows programmers to programmatically define a schema in a portable
+  # DSL. This means you can define tables, indexes, etc. without using SQL
+  # directly, so your applications can more easily support multiple
+  # databases.
+  #
+  # Usage:
+  #
+  #   ActiveRecord::Schema.define do
+  #     create_table :authors do |t|
+  #       t.string :name, :null => false
+  #     end
+  #
+  #     add_index :authors, :name, :unique
+  #
+  #     create_table :posts do |t|
+  #       t.integer :author_id, :null => false
+  #       t.string :subject
+  #       t.text :body
+  #       t.boolean :private, :default => false
+  #     end
+  #
+  #     add_index :posts, :author_id
+  #   end
+  #
+  # ActiveRecord::Schema is only supported by database adapters that also
+  # support migrations, the two features being very similar.
+  class Schema < Migration
+    private_class_method :new
+
+    # Eval the given block. All methods available to the current connection
+    # adapter are available within the block, so you can easily use the
+    # database definition DSL to build up your schema (+create_table+,
+    # +add_index+, etc.).
+    #
+    # The +info+ hash is optional, and if given is used to define metadata
+    # about the current schema (currently, only the schema's version):
+    #
+    #   ActiveRecord::Schema.define(:version => 20380119000001) do
+    #     ...
+    #   end
+    def self.define(info={}, &block)
+      instance_eval(&block)
+
+      unless info[:version].blank?
+        initialize_schema_migrations_table
+        assume_migrated_upto_version info[:version]
+      end
