+ActsAsList
+==========
+
+This acts_as extension provides the capabilities for sorting and reordering a number of objects in a list. The class that has this specified needs to have a +position+ column defined as an integer on the mapped database table.
+
+
+Example
+=======
+
+  class TodoList < ActiveRecord::Base
+    has_many :todo_items, :order => "position"
+  end
+
+  class TodoItem < ActiveRecord::Base
+    belongs_to :todo_list
+    acts_as_list :scope => :todo_list
+  end
+
+  todo_list.first.move_to_bottom
+  todo_list.last.move_higher

+Specify this +acts_as+ extension if you want to model a tree structure by providing a parent association and a children
+association. This requires that you have a foreign key column, which by default is called +parent_id+.
+
+  class Category < ActiveRecord::Base
+    acts_as_tree :order => "name"

+
+  root      = Category.create("name" => "root")

+== Creating the test database
+
+The default name for the test databases is "activerecord_versioned". If you 
+want to use another database name then be sure to update the connection 
+adapter setups you want to test with in test/connections/<your database>/connection.rb. 
+When you have the database online, you can import the fixture tables with 
+the test/fixtures/db_definitions/*.sql files.
+
+Make sure that you create database objects with the same user that you specified in i
+connection.rb otherwise (on Postgres, at least) tests for default values will fail.
+
+== Running with Rake
+
+The easiest way to run the unit tests is through Rake. The default task runs
+the entire test suite for all the adapters. You can also run the suite on just
+one adapter by using the tasks test_mysql_ruby, test_ruby_mysql, test_sqlite, 
+or test_postresql. For more information, checkout the full array of rake tasks with "rake -T"
+
+Rake can be found at http://rake.rubyforge.org
+
+== Running by hand
+
+Unit tests are located in test directory. If you only want to run a single test suite, 
+or don't want to bother with Rake, you can do so with something like:
+
+   cd test; ruby -I "connections/native_mysql" base_test.rb
+   
+That'll run the base suite using the MySQL-Ruby adapter. Change the adapter
+and test suite name as needed.
+
+== Faster tests
+
+If you are using a database that supports transactions, you can set the
+"AR_TX_FIXTURES" environment variable to "yes" to use transactional fixtures.
+This gives a very large speed boost. With rake:
+
+  rake AR_TX_FIXTURES=yes
+
+Or, by hand:
+
+  AR_TX_FIXTURES=yes ruby -I connections/native_sqlite3 base_test.rb

+    #
+    # The class for the versioned model is derived the first time it is seen. Therefore, if you change your database schema you have to restart

+        # * <tt>class_name</tt> - versioned model class name (default: PageVersion in the above example)
+        # * <tt>table_name</tt> - versioned model table name (default: page_versions in the above example)
+        # * <tt>foreign_key</tt> - foreign key used to relate the versioned model to the original model (default: page_id in the above example)
+        # * <tt>inheritance_column</tt> - name of the column to save the model's inheritance_column value for STI.  (default: versioned_type)
+        # * <tt>version_column</tt> - name of the column in the model that keeps the version number (default: version)
+        # * <tt>sequence_name</tt> - name of the custom sequence to be used by the versioned model.
+        # * <tt>limit</tt> - number of revisions to keep, defaults to unlimited
+        # * <tt>if</tt> - symbol of method to check before saving a new version.  If this method returns false, a new version is not saved.
+        #   For finer control, pass either a Proc or modify Model#version_condition_met?
+        #
+        #     acts_as_versioned :if => Proc.new { |auction| !auction.expired? }

+        # * <tt>if_changed</tt> - Simple way of specifying attributes that are required to be changed before saving a model.  This takes
+        #   either a symbol or array of symbols.  WARNING - This will attempt to overwrite any attribute setters you may have.
+        #   Use this instead if you want to write your own attribute setters (and ignore if_changed):
+        # 
+        #     def name=(new_name)

+        #     end

+        # * <tt>extend</tt> - Lets you specify a module to be mixed in both the original and versioned models.  You can also just pass a block
+        #   to create an anonymous mixin:

+        # == Database Schema
+        #
+        # The model that you're versioning needs to have a 'version' attribute. The model is versioned 
+        # into a table called #{model}_versions where the model name is singlular. The _versions table should 
+        # contain all the fields you want versioned, the same version column, and a #{model}_id foreign key field.
+        #
+        # A lock_version field is also accepted if your model uses Optimistic Locking.  If your table uses Single Table inheritance,
+        # then that field is reflected in the versioned model as 'versioned_type' by default.
+        #
+        # Acts_as_versioned comes prepared with the ActiveRecord::Acts::Versioned::ActMethods::ClassMethods#create_versioned_table 
+        # method, perfect for a migration.  It will also create the version column if the main model does not already have it.

+== Gravatar Plugin
+
+This plugin provides a handful of view helpers for displaying gravatars 
+(globally-recognized avatars). 
+
+Gravatars allow users to configure an avatar to go with their email address at
+a central location: http://gravatar.com. Gravatar-aware websites (such
+as yours) can then look up and display each user's preferred avatar, without
+having to handle avatar management. The user gets the benefit of not having to
+set up an avatar for each site that they post on.
+
+== Installation
+
+  cd ~/myapp
+  ruby script/plugin install git://github.com/woods/gravatar-plugin.git
+
+or, if you're using piston[http://piston.rubyforge.org] (worth it!):
+
+  cd ~/myapp/vendor/plugins
+  piston import git://github.com/woods/gravatar-plugin.git
+
+== Example
+
+If you represent your users with a model that has an +email+ method (typical
+for most rails authentication setups), then you can simply use this method
+in your views:
+
+  <%= gravatar_for @user %>
+  
+This will be replaced with the full HTML +img+ tag necessary for displaying 
+that user's gravatar.
+
+Other helpers are documented under GravatarHelper::PublicMethods.
+
+== Acknowledgments
+
+Thanks to Magnus Bergmark (http://github.com/Mange), who contributed the SSL
+support in this plugin, as well as a few minor fixes.
+
+The following people have also written gravatar-related Ruby libraries:
+* Seth Rasmussen created the gravatar gem[http://gravatar.rubyforge.org]
+* Matt McCray has also created a gravatar 
+  plugin[http://mattmccray.com/svn/rails/plugins/gravatar_helper]

+OpenIdAuthentication
+====================
+
+Provides a thin wrapper around the excellent ruby-openid gem from JanRan. Be sure to install that first:
+
+  gem install ruby-openid
+
+To understand what OpenID is about and how it works, it helps to read the documentation for lib/openid/consumer.rb
+from that gem.
+
+The specification used is http://openid.net/specs/openid-authentication-2_0.html.
+
+
+Prerequisites
+=============
+
+OpenID authentication uses the session, so be sure that you haven't turned that off.
+
+Alternatively, you can use the file-based store, which just relies on on tmp/openids being present in RAILS_ROOT. But be aware that this store only works if you have a single application server. And it's not safe to use across NFS. It's recommended that you use the database store if at all possible. To use the file-based store, you'll also have to add this line to your config/environment.rb:
+
+  OpenIdAuthentication.store = :file
+
+This particular plugin also relies on the fact that the authentication action allows for both POST and GET operations.
+If you're using RESTful authentication, you'll need to explicitly allow for this in your routes.rb.
+
+The plugin also expects to find a root_url method that points to the home page of your site. You can accomplish this by using a root route in config/routes.rb:
+
+  map.root :controller => 'articles'
+
+This plugin relies on Rails Edge revision 6317 or newer.
+
+
+Example
+=======
+
+This example is just to meant to demonstrate how you could use OpenID authentication. You might well want to add
+salted hash logins instead of plain text passwords and other requirements on top of this. Treat it as a starting point,
+not a destination.
+
+Note that the User model referenced in the simple example below has an 'identity_url' attribute. You will want to add the same or similar field to whatever
+model you are using for authentication.
+
+Also of note is the following code block used in the example below:
+
+  authenticate_with_open_id do |result, identity_url|
+    ...
+  end
+
+In the above code block, 'identity_url' will need to match user.identity_url exactly. 'identity_url' will be a string in the form of 'http://example.com' -
+If you are storing just 'example.com' with your user, the lookup will fail.
+
+There is a handy method in this plugin called 'normalize_url' that will help with validating OpenID URLs.
+
+  OpenIdAuthentication.normalize_url(user.identity_url)
+
+The above will return a standardized version of the OpenID URL - the above called with 'example.com' will return 'http://example.com/'
+It will also raise an InvalidOpenId exception if the URL is determined to not be valid.
+Use the above code in your User model and validate OpenID URLs before saving them.
+
+config/routes.rb
+
+  map.root :controller => 'articles'
+  map.resource :session
+
+
+app/views/sessions/new.erb

+      def failed_login(message)
+        flash[:error] = message
+        redirect_to(new_session_url)
+      end
+  end
+
+
+
+If you're fine with the result messages above and don't need individual logic on a per-failure basis,
+you can collapse the case into a mere boolean:
+
+    def open_id_authentication
+      authenticate_with_open_id do |result, identity_url|
+        if result.successful? && @current_user = @account.users.find_by_identity_url(identity_url)
+          successful_login
+        else
+          failed_login(result.message || "Sorry, no user by that identity URL exists (#{identity_url})")
+        end
+      end
+    end
+
+
+Simple Registration OpenID Extension
+====================================
+
+Some OpenID Providers support this lightweight profile exchange protocol.  See more: http://www.openidenabled.com/openid/simple-registration-extension
+
+You can support it in your app by changing #open_id_authentication
+
+      def open_id_authentication(identity_url)
+        # Pass optional :required and :optional keys to specify what sreg fields you want.
+        # Be sure to yield registration, a third argument in the #authenticate_with_open_id block.
+        authenticate_with_open_id(identity_url,
+            :required => [ :nickname, :email ],
+            :optional => :fullname) do |result, identity_url, registration|
+          case result.status
+          when :missing
+            failed_login "Sorry, the OpenID server couldn't be found"
+          when :invalid
+            failed_login "Sorry, but this does not appear to be a valid OpenID"
+          when :canceled
+            failed_login "OpenID verification was canceled"
+          when :failed
+            failed_login "Sorry, the OpenID verification failed"
+          when :successful
+            if @current_user = @account.users.find_by_identity_url(identity_url)
+              assign_registration_attributes!(registration)
+
+              if current_user.save
+                successful_login
+              else
+                failed_login "Your OpenID profile registration failed: " +
+                  @current_user.errors.full_messages.to_sentence
+              end
+            else
+              failed_login "Sorry, no user by that identity URL exists"
+            end
+          end
+        end
+      end
+
+      # registration is a hash containing the valid sreg keys given above
+      # use this to map them to fields of your user model
+      def assign_registration_attributes!(registration)
+        model_to_registration_mapping.each do |model_attribute, registration_attribute|
+          unless registration[registration_attribute].blank?
+            @current_user.send("#{model_attribute}=", registration[registration_attribute])
+          end
+        end
+      end
+
+      def model_to_registration_mapping
+        { :login => 'nickname', :email => 'email', :display_name => 'fullname' }
+      end
+
+Attribute Exchange OpenID Extension
+===================================
+
+Some OpenID providers also support the OpenID AX (attribute exchange) protocol for exchanging identity information between endpoints.  See more: http://openid.net/specs/openid-attribute-exchange-1_0.html
+
+Accessing AX data is very similar to the Simple Registration process, described above -- just add the URI identifier for the AX field to your :optional or :required parameters.  For example:
+
+        authenticate_with_open_id(identity_url,
+            :required => [ :email, 'http://schema.openid.net/birthDate' ]) do |result, identity_url, registration|
+
+This would provide the sreg data for :email, and the AX data for 'http://schema.openid.net/birthDate'
