-    Person.find(:all, :title => "CEO")      ...becomes: Person.find(:all, :params => { :title => "CEO" })
-    Person.find(:managers)                  ...becomes: Person.find(:all, :from => :managers)
-    Person.find("/companies/1/manager.xml") ...becomes: Person.find(:one, :from => "/companies/1/manager.xml")
-
-* Add support for setting custom headers per Active Resource model [Rick Olson]
-
-  class Project
-    headers['X-Token'] = 'foo'
-  end
-  
-  # makes the GET request with the custom X-Token header
-  Project.find(:all)
-
-* Added find-by-path options to ActiveResource::Base.find [David Heinemeier Hansson]. Examples:
-
-    employees = Person.find(:all, :from => "/companies/1/people.xml") # => GET /companies/1/people.xml
-    manager   = Person.find("/companies/1/manager.xml")               # => GET /companies/1/manager.xml
-
-
-* Added support for using classes from within a single nested module [David Heinemeier Hansson]. Example:
-
-    module Highrise
-      class Note < ActiveResource::Base
-        self.site = "http://37s.sunrise.i:3000"
-      end
-
-      class Comment < ActiveResource::Base
-        self.site = "http://37s.sunrise.i:3000"
-      end
-    end
-
-  assert_kind_of Highrise::Comment, Note.find(1).comments.first
-    
-
-* Added load_attributes_from_response as a way of loading attributes from other responses than just create [David Heinemeier Hansson]
-
-    class Highrise::Task < ActiveResource::Base
-      def complete
-        load_attributes_from_response(post(:complete))
-      end
-    end
-
-  ...will set "done_at" when complete is called.
-
-
-* Added support for calling custom methods #6979 [rwdaigle]
-
-    Person.find(:managers)    # => GET /people/managers.xml
-    Kase.find(1).post(:close) # => POST /kases/1/close.xml
-
-* Remove explicit prefix_options parameter for ActiveResource::Base#initialize. [Rick Olson]
-  ActiveResource splits the prefix_options from it automatically.
-
-* Allow ActiveResource::Base.delete with custom prefix. [Rick Olson]
-
-* Add ActiveResource::Base#dup [Rick Olson]
-
-* Fixed constant warning when fetching the same object multiple times [David Heinemeier Hansson]
-
-* Added that saves which get a body response (and not just a 201) will use that response to update themselves [David Heinemeier Hansson]
-
-* Disregard namespaces from the default element name, so Highrise::Person will just try to fetch from "/people", not "/highrise/people" [David Heinemeier Hansson]
-
-* Allow array and hash query parameters.  #7756 [Greg Spurrier]
-
-* Loading a resource preserves its prefix_options.  #7353 [Ryan Daigle]
-
-* Carry over the convenience of #create from ActiveRecord.  Closes #7340.  [Ryan Daigle]
-
-* Increase ActiveResource::Base test coverage.  Closes #7173, #7174 [Rich Collins]
-
-* Interpret 422 Unprocessable Entity as ResourceInvalid.  #7097 [dkubb]
-
-* Mega documentation patches. #7025, #7069 [rwdaigle]
-
-* Base.exists?(id, options) and Base#exists? check whether the resource is found.  #6970 [rwdaigle]
-
-* Query string support.  [untext, Jeremy Kemper]
-    # GET /forums/1/topics.xml?sort=created_at
-    Topic.find(:all, :forum_id => 1, :sort => 'created_at')
-
-* Base#==, eql?, and hash methods. == returns true if its argument is identical to self or if it's an instance of the same class, is not new?, and has the same id. eql? is an alias for ==. hash delegates to id.  [Jeremy Kemper]
-
-* Allow subclassed resources to share the site info [Rick Olson, Jeremy Kemper]
-d
-    class BeastResource < ActiveResource::Base
-      self.site = 'http://beast.caboo.se'
-    end
-
-    class Forum < BeastResource
-      # taken from BeastResource
-      # self.site = 'http://beast.caboo.se'
-    end
-
-    class Topic < BeastResource
-      self.site += '/forums/:forum_id'
-    end
-
-* Fix issues with ActiveResource collection handling.  Closes #6291. [bmilekic]
-
-* Use attr_accessor_with_default to dry up attribute initialization. References #6538. [Stuart Halloway]
-
-* Add basic logging support for logging outgoing requests. [Jamis Buck]
-
-* Add Base.delete for deleting resources without having to instantiate them first. [Jamis Buck]
-
-* Make #save behavior mimic AR::Base#save (true on success, false on failure). [Jamis Buck]
-
-* Add Basic HTTP Authentication to ActiveResource (closes #6305). [jonathan]
-
-* Extracted #id_from_response as an entry point for customizing how a created resource gets its own ID.
-  By default, it extracts from the Location response header.
-
-* Optimistic locking: raise ActiveResource::ResourceConflict on 409 Conflict response. [Jeremy Kemper]
-
-    # Example controller action
-    def update
-      @person.save!
-    rescue ActiveRecord::StaleObjectError
-      render :xml => @person.reload.to_xml, :status => '409 Conflict'
-    end
-
-* Basic validation support [Rick Olson]
-
-  Parses the xml response of ActiveRecord::Errors#to_xml with a similar interface to ActiveRecord::Errors.  
-  
-    render :xml => @person.errors.to_xml, :status => '400 Validation Error'
-
-* Deep hashes are converted into collections of resources.  [Jeremy Kemper]
-    Person.new :name => 'Bob',
-               :address => { :id => 1, :city => 'Portland' },
-               :contacts => [{ :id => 1 }, { :id => 2 }]
-  Looks for Address and Contact resources and creates them if unavailable.
-  So clients can fetch a complex resource in a single request if you e.g.
-    render :xml => @person.to_xml(:include => [:address, :contacts])
-  in your controller action.
-
-* Major updates [Rick Olson]
-
-  * Add full support for find/create/update/destroy
-  * Add support for specifying prefixes.
-  * Allow overriding of element_name, collection_name, and primary key
-  * Provide simpler HTTP mock interface for testing
-  
-    # rails routing code
-    map.resources :posts do |post|
-      post.resources :comments
-    end
-    
-    # ActiveResources
-    class Post < ActiveResource::Base
-      self.site = "http://37s.sunrise.i:3000/"
-    end
-
-    class Comment < ActiveResource::Base
-      self.site = "http://37s.sunrise.i:3000/posts/:post_id/"
-    end
-    
-    @post     = Post.find 5
-    @comments = Comment.find :all, :post_id => @post.id
-
-    @comment  = Comment.new({:body => 'hello world'}, {:post_id => @post.id})
-    @comment.save
-
-* Base.site= accepts URIs. 200...400 are valid response codes. PUT and POST request bodies default to ''. [Jeremy Kemper]
-
-* Initial checkin: object-oriented client for restful HTTP resources which follow the Rails convention. [David Heinemeier Hansson]

-= Active Resource
-
-Active Resource (ARes) connects business objects and Representational State Transfer (REST)
-web services.  It implements object-relational mapping for REST webservices to provide transparent 
-proxying capabilities between a client (ActiveResource) and a RESTful service (which is provided by Simply RESTful routing
-in ActionController::Resources).
-
-== Philosophy
-
-Active Resource attempts to provide a coherent wrapper object-relational mapping for REST
-web services. It follows the same philosophy as Active Record, in that one of its prime aims
-is to reduce the amount of code needed to map to these resources.  This is made possible 
-by relying on a number of code- and protocol-based conventions that make it easy for Active Resource
-to infer complex relations and structures.  These conventions are outlined in detail in the documentation
-for ActiveResource::Base.
-
-== Overview
-
-Model classes are mapped to remote REST resources by Active Resource much the same way Active Record maps model classes to database
-tables.  When a request is made to a remote resource, a REST XML request is generated, transmitted, and the result
-received and serialized into a usable Ruby object.
-
-=== Configuration and Usage
-
-Putting ActiveResource to use is very similar to ActiveRecord.  It's as simple as creating a model class
-that inherits from ActiveResource::Base and providing a <tt>site</tt> class variable to it:
-
-   class Person < ActiveResource::Base
-     self.site = "http://api.people.com:3000/"
-   end
-
-Now the Person class is REST enabled and can invoke REST services very similarly to how ActiveRecord invokes
-lifecycle methods that operate against a persistent store.
-
-   # Find a person with id = 1
-   ryan = Person.find(1)
-   Person.exists?(1)  #=> true
-
-As you can see, the methods are quite similar to Active Record's methods for dealing with database
-records.  But rather than dealing directly with a database record, you're dealing with HTTP resources (which may or may not be database records).
-
-==== Protocol
-
-Active Resource is built on a standard XML format for requesting and submitting resources over HTTP.  It mirrors the RESTful routing 
-built into ActionController but will also work with any other REST service that properly implements the protocol. 
-REST uses HTTP, but unlike "typical" web applications, it makes use of all the verbs available in the HTTP specification:
-
-* GET requests are used for finding and retrieving resources.
-* POST requests are used to create new resources.
-* PUT requests are used to update existing resources.
-* DELETE requests are used to delete resources. 
-
-For more information on how this protocol works with Active Resource, see the ActiveResource::Base documentation;
-for more general information on REST web services, see the article here[http://en.wikipedia.org/wiki/Representational_State_Transfer].
-
-==== Find
-
-GET Http requests expect the XML form of whatever resource/resources is/are being requested.  So,
-for a request for a single element - the XML of that item is expected in response:
-
-   # Expects a response of
-   #
-   # <person><id type="integer">1</id><attribute1>value1</attribute1><attribute2>..</attribute2></person>
-   #
-   # for GET http://api.people.com:3000/people/1.xml
-   #
-   ryan = Person.find(1)
-
-The XML document that is received is used to build a new object of type Person, with each
-XML element becoming an attribute on the object.
-
-   ryan.is_a? Person  #=> true
-   ryan.attribute1  #=> 'value1'
-
-Any complex element (one that contains other elements) becomes its own object:
-
-   # With this response:
-   #
-   # <person><id>1</id><attribute1>value1</attribute1><complex><attribute2>value2</attribute2></complex></person>
-   #
-   # for GET http://api.people.com:3000/people/1.xml
-   #
-   ryan = Person.find(1)
-   ryan.complex  #=> <Person::Complex::xxxxx>
-   ryan.complex.attribute2  #=> 'value2'
-
-Collections can also be requested in a similar fashion
-
-   # Expects a response of
-   #
-   # <people type="array">
-   #  <person><id type="integer">1</id><first>Ryan</first></person>
-   #  <person><id type="integer">2</id><first>Jim</first></person>
-   # </people>
-   #
-   # for GET http://api.people.com:3000/people.xml
-   #
-   people = Person.find(:all)
-   people.first  #=> <Person::xxx 'first' => 'Ryan' ...>
-   people.last  #=> <Person::xxx 'first' => 'Jim' ...>
-
-==== Create
-
-Creating a new resource submits the xml form of the resource as the body of the request and expects
-a 'Location' header in the response with the RESTful URL location of the newly created resource.  The
-id of the newly created resource is parsed out of the Location response header and automatically set
-as the id of the ARes object.
-
-  # <person><first>Ryan</first></person>
-  #
-  # is submitted as the body on
-  #
-  # POST http://api.people.com:3000/people.xml
-  # 
-  # when save is called on a new Person object.  An empty response is
-  # is expected with a 'Location' header value:
-  #
-  # Response (201): Location: http://api.people.com:3000/people/2
-  #
-  ryan = Person.new(:first => 'Ryan')
-  ryan.new?  #=> true
-  ryan.save  #=> true
-  ryan.new?  #=> false
-  ryan.id    #=> 2
-
-==== Update
-
-'save' is also used to update an existing resource - and follows the same protocol as creating a resource
-with the exception that no response headers are needed - just an empty response when the update on the
-server side was successful.
-
-  # <person><first>Ryan</first></person>
-  #
-  # is submitted as the body on
-  #
-  # PUT http://api.people.com:3000/people/1.xml
-  #
-  # when save is called on an existing Person object.  An empty response is
-  # is expected with code (204)
-  #
-  ryan = Person.find(1)
-  ryan.first #=> 'Ryan'
-  ryan.first = 'Rizzle'
-  ryan.save  #=> true
-
-==== Delete
-
-Destruction of a resource can be invoked as a class and instance method of the resource.
-
-  # A request is made to
-  #
-  # DELETE http://api.people.com:3000/people/1.xml
-  #
-  # for both of these forms.  An empty response with
-  # is expected with response code (200)
-  #
-  ryan = Person.find(1)
-  ryan.destroy  #=> true
-  ryan.exists?  #=> false
-  Person.delete(2)  #=> true
-  Person.exists?(2) #=> false
-
-
-You can find more usage information in the ActiveResource::Base documentation.

-  # say you use Rails to expose a REST service and configure your routes with:
-  #
-  #    map.resources :people, :new => { :register => :post },
-  #                           :member => { :promote => :put, :deactivate => :delete }
-  #                           :collection => { :active => :get }

-  #  This route set creates routes for the following HTTP requests:
-  #
-  #    POST    /people/new/register.xml # PeopleController.register
-  #    PUT     /people/1/promote.xml    # PeopleController.promote with :id => 1
-  #    DELETE  /people/1/deactivate.xml # PeopleController.deactivate with :id => 1
-  #    GET     /people/active.xml       # PeopleController.active
-  #
-  # Using this module, Active Resource can use these custom REST methods just like the
-  # standard methods.

-  # One thing that has always been a pain with remote web services is testing.  The HttpMock
-  # class makes it easy to test your Active Resource models by creating a set of mock responses to specific
-  # requests.
-  #
-  # To test your Active Resource model, you simply call the ActiveResource::HttpMock.respond_to
-  # method with an attached block.  The block declares a set of URIs with expected input, and the output
-  # each request should return.  The passed in block has any number of entries in the following generalized
-  # format:
-  #
-  #   mock.http_method(path, request_headers = {}, body = nil, status = 200, response_headers = {})
-  #
-  # * <tt>http_method</tt> - The HTTP method to listen for.  This can be +get+, +post+, +put+, +delete+ or
-  #   +head+.
-  # * <tt>path</tt> - A string, starting with a "/", defining the URI that is expected to be
-  #   called.
-  # * <tt>request_headers</tt> - Headers that are expected along with the request.  This argument uses a
-  #   hash format, such as <tt>{ "Content-Type" => "application/xml" }</tt>.  This mock will only trigger
-  #   if your tests sends a request with identical headers.
-  # * <tt>body</tt> - The data to be returned.  This should be a string of Active Resource parseable content,
-  #   such as XML.
-  # * <tt>status</tt> - The HTTP response code, as an integer, to return with the response.
-  # * <tt>response_headers</tt> - Headers to be returned with the response.  Uses the same hash format as
-  #   <tt>request_headers</tt> listed above.
-  #
-  # In order for a mock to deliver its content, the incoming request must match by the <tt>http_method</tt>,
-  # +path+ and <tt>request_headers</tt>.  If no match is found an InvalidRequestError exception
-  # will be raised showing you what request it could not find a response for and also what requests and response
-  # pairs have been recorded so you can create a new mock for that request.

-    # to share cache data with each other. If your application never performs
-    # manual cache item expiry (e.g. when you're using generational cache keys),

 module ActiveSupport
-  # Callbacks are hooks into the lifecycle of an object that allow you to trigger logic
-  # before or after an alteration of the object state.
+  # \Callbacks are code hooks that are run at key points in an object's lifecycle.
+  # The typical use case is to have a base class define a set of callbacks relevant
+  # to the other functionality it supplies, so that subclasses can install callbacks
+  # that enhance or modify the base functionality without needing to override
+  # or redefine methods of the base class.
   #
-  # Mixing in this module allows you to define callbacks in your class.
+  # Mixing in this module allows you to define the events in the object's lifecycle
+  # that will support callbacks (via +ClassMethods.define_callbacks+), set the instance
+  # methods, procs, or callback objects to be called (via +ClassMethods.set_callback+),
+  # and run the installed callbacks at the appropriate times (via +run_callbacks+).
   #
-  # Example:
-  #   class Storage
+  # Three kinds of callbacks are supported: before callbacks, run before a certain event;
+  # after callbacks, run after the event; and around callbacks, blocks that surround the
+  # event, triggering it when they yield. Callback code can be contained in instance
+  # methods, procs or lambdas, or callback objects that respond to certain predetermined
+  # methods. See +ClassMethods.set_callback+ for details.
+  #
+  # ==== Example
+  #
+  #   class Record
   #     include ActiveSupport::Callbacks
+  #     define_callbacks :save
   #
-  #     define_callbacks :before_save, :after_save
+  #     def save
+  #       run_callbacks :save do
+  #         puts "- save"
+  #       end
+  #     end
   #   end
   #
-  #   class ConfigStorage < Storage
-  #     before_save :saving_message
+  #   class PersonRecord < Record
+  #     set_callback :save, :before, :saving_message
   #     def saving_message
   #       puts "saving..."
   #     end
   #
-  #     after_save do |object|
+  #     set_callback :save, :after do |object|
   #       puts "saved"
   #     end
-  #
-  #     def save
-  #       run_callbacks(:before_save)
-  #       puts "- save"
-  #       run_callbacks(:after_save)
-  #     end
   #   end
   #
-  #   config = ConfigStorage.new
-  #   config.save
+  #   person = PersonRecord.new
+  #   person.save
   #
   # Output:
   #   saving...
   #   - save
   #   saved
   #
-  # Callbacks from parent classes are inherited.
-  #
-  # Example:
-  #   class Storage
-  #     include ActiveSupport::Callbacks

+      #
+      #   set_callback :save, :before_meth
+      #
+      # The callback can specified as a symbol naming an instance method; as a proc,

+      # responds to a certain method determined by the <tt>:scope</tt> argument to
+      # +define_callback+.
+      #
+      # If a proc, lambda, or block is given, its body is evaluated in the context
+      # of the current object. It can also optionally accept the current object as
+      # an argument.
+      #
+      # Before and around callbacks are called in the order that they are set; after
+      # callbacks are called in the reverse order.
+      # 
+      # Around callbacks can access the return value from the event, if it

+      #
+      # ===== Options
+      #
+      # * <tt>:if</tt> - A symbol naming an instance method or a proc; the callback
+      #   will be called only when it returns a true value.
+      # * <tt>:unless</tt> - A symbol naming an instance method or a proc; the callback
+      #   will be called only when it returns a false value.
+      # * <tt>:prepend</tt> - If true, the callback will be prepended to the existing
+      #   chain rather than appended.
+      # * <tt>:per_key</tt> - A hash with <tt>:if</tt> and <tt>:unless</tt> options;
+      #   see "Per-key conditions" below.
+      #
+      # ===== Per-key conditions
+      #
+      # When creating or skipping callbacks, you can specify conditions that
+      # are always the same for a given key. For instance, in Action Pack,
+      # we convert :only and :except conditions into per-key conditions.
+      #
+      #   before_filter :authenticate, :except => "index"
+      #
+      # becomes
+      #
+      #   set_callback :process_action, :before, :authenticate, :per_key => {:unless => proc {|c| c.action_name == "index"}}
+      #
+      # Per-key conditions are evaluated only once per use of a given key.
+      # In the case of the above example, you would do:
+      #
+      #   run_callbacks(:process_action, action_name) { ... dispatch stuff ... }
+      #
+      # In that case, each action_name would get its own compiled callback
+      # method that took into consideration the per_key conditions. This
+      # is a speed improvement for ActionPack.

+      #   triggered. This is a string to be eval'ed. The result of the callback is available

+      #
+      #     define_callbacks :validate, :terminator => "result == false"
+      #
+      #   In this example, if any before validate callbacks returns +false+,
+      #   other callbacks are not executed. Defaults to "false", meaning no value
+      #   halts the chain.
+      #
+      # * <tt>:rescuable</tt> - By default, after filters are not executed if
+      #   the given block or a before filter raises an error. By setting this option
+      #   to <tt>true</tt> exception raised by given block is stored and after
+      #   executing all the after callbacks the stored exception is raised.
+      #
+      # * <tt>:scope</tt> - Indicates which methods should be executed when an object
+      #   is used as a callback.
