+module ActiveResource
+  # ActiveResource::Base is the main class for mapping RESTful resources as models in a Rails application.
+  #
+  # For an outline of what Active Resource is capable of, see link:files/vendor/rails/activeresource/README.html.
+  #
+  # == Automated mapping
+  #
+  # Active Resource objects represent your RESTful resources as manipulatable Ruby objects.  To map resources
+  # to Ruby objects, Active Resource only needs a class name that corresponds to the resource name (e.g., the class
+  # Person maps to the resources people, very similarly to Active Record) and a +site+ value, which holds the
+  # URI of the resources.
+  # 
+  #   class Person < ActiveResource::Base
+  #     self.site = "http://api.people.com:3000/"
+  #   end
+  # 
+  # Now the Person class is mapped to RESTful resources located at <tt>http://api.people.com:3000/people/</tt>, and
+  # you can now use Active Resource's lifecycles methods to manipulate resources. In the case where you already have 
+  # an existing model with the same name as the desired RESTful resource you can set the +element_name+ value.
+  #
+  #   class PersonResource < ActiveResource::Base
+  #     self.site = "http://api.people.com:3000/"
+  #     self.element_name = "person"
+  #   end
+  #  
+  # 
+  # == Lifecycle methods
+  #
+  # Active Resource exposes methods for creating, finding, updating, and deleting resources
+  # from REST web services.
+  # 
+  #   ryan = Person.new(:first => 'Ryan', :last => 'Daigle')
+  #   ryan.save                # => true
+  #   ryan.id                  # => 2
+  #   Person.exists?(ryan.id)  # => true
+  #   ryan.exists?             # => true
+  # 
+  #   ryan = Person.find(1)
+  #   # Resource holding our newly created Person object
+  # 
+  #   ryan.first = 'Rizzle'
+  #   ryan.save                # => true
+  # 
+  #   ryan.destroy             # => true
+  #
+  # As you can see, these are very similar to Active Record's lifecycle methods for database records.
+  # You can read more about each of these methods in their respective documentation.
+  # 
+  # === Custom REST methods
+  #
+  # Since simple CRUD/lifecycle methods can't accomplish every task, Active Resource also supports
+  # defining your own custom REST methods. To invoke them, Active Resource provides the <tt>get</tt>,
+  # <tt>post</tt>, <tt>put</tt> and <tt>delete</tt> methods where you can specify a custom REST method
+  # name to invoke.
+  #
+  #   # POST to the custom 'register' REST method, i.e. POST /people/new/register.xml.
+  #   Person.new(:name => 'Ryan').post(:register)
+  #   # => { :id => 1, :name => 'Ryan', :position => 'Clerk' }
+  #
+  #   # PUT an update by invoking the 'promote' REST method, i.e. PUT /people/1/promote.xml?position=Manager.
+  #   Person.find(1).put(:promote, :position => 'Manager')
+  #   # => { :id => 1, :name => 'Ryan', :position => 'Manager' }
+  #
+  #   # GET all the positions available, i.e. GET /people/positions.xml.
+  #   Person.get(:positions)
+  #   # => [{:name => 'Manager'}, {:name => 'Clerk'}]
+  #
+  #   # DELETE to 'fire' a person, i.e. DELETE /people/1/fire.xml.
+  #   Person.find(1).delete(:fire)
+  # 
+  # For more information on using custom REST methods, see the
+  # ActiveResource::CustomMethods documentation.
+  #
+  # == Validations
+  #
+  # You can validate resources client side by overriding validation methods in the base class.
+  # 
+  #   class Person < ActiveResource::Base
+  #      self.site = "http://api.people.com:3000/"
+  #      protected
+  #        def validate
+  #          errors.add("last", "has invalid characters") unless last =~ /[a-zA-Z]*/
+  #        end
+  #   end
+  # 
+  # See the ActiveResource::Validations documentation for more information.
+  #
+  # == Authentication
+  # 
+  # Many REST APIs will require authentication, usually in the form of basic
+  # HTTP authentication.  Authentication can be specified by:
+  # * putting the credentials in the URL for the +site+ variable.
+  # 
+  #    class Person < ActiveResource::Base
+  #      self.site = "http://ryan:password@api.people.com:3000/"
+  #    end
+  # 
+  # * defining +user+ and/or +password+ variables
+  #
+  #    class Person < ActiveResource::Base
+  #      self.site = "http://api.people.com:3000/"
+  #      self.user = "ryan"
+  #      self.password = "password"
+  #    end
+  #
+  # For obvious security reasons, it is probably best if such services are available 
+  # over HTTPS.
+  # 
+  # Note: Some values cannot be provided in the URL passed to site.  e.g. email addresses 
+  # as usernames.  In those situations you should use the seperate user and password option.
+  # == Errors & Validation
+  #
+  # Error handling and validation is handled in much the same manner as you're used to seeing in
+  # Active Record.  Both the response code in the HTTP response and the body of the response are used to
+  # indicate that an error occurred.
+  # 
+  # === Resource errors
+  # 
+  # When a GET is requested for a resource that does not exist, the HTTP <tt>404</tt> (Resource Not Found)
+  # response code will be returned from the server which will raise an ActiveResource::ResourceNotFound
+  # exception.
+  # 
+  #   # GET http://api.people.com:3000/people/999.xml
+  #   ryan = Person.find(999) # 404, raises ActiveResource::ResourceNotFound
+  # 
+  # <tt>404</tt> is just one of the HTTP error response codes that Active Resource will handle with its own exception. The
+  # following HTTP response codes will also result in these exceptions:
+  # 
+  # * 200..399 - Valid response, no exception
+  # * 404 - ActiveResource::ResourceNotFound
+  # * 409 - ActiveResource::ResourceConflict
+  # * 422 - ActiveResource::ResourceInvalid (rescued by save as validation errors)
+  # * 401..499 - ActiveResource::ClientError
+  # * 500..599 - ActiveResource::ServerError
+  #
+  # These custom exceptions allow you to deal with resource errors more naturally and with more precision
+  # rather than returning a general HTTP error.  For example:
+  #
+  #   begin
+  #     ryan = Person.find(my_id)
+  #   rescue ActiveResource::ResourceNotFound
+  #     redirect_to :action => 'not_found'
+  #   rescue ActiveResource::ResourceConflict, ActiveResource::ResourceInvalid
+  #     redirect_to :action => 'new'
+  #   end
+  #
+  # === Validation errors
+  # 
+  # Active Resource supports validations on resources and will return errors if any these validations fail
+  # (e.g., "First name can not be blank" and so on).  These types of errors are denoted in the response by 
+  # a response code of <tt>422</tt> and an XML representation of the validation errors.  The save operation will
+  # then fail (with a <tt>false</tt> return value) and the validation errors can be accessed on the resource in question.
+  # 
+  #   ryan = Person.find(1)
+  #   ryan.first # => ''
+  #   ryan.save  # => false
+  #
+  #   # When 
+  #   # PUT http://api.people.com:3000/people/1.xml
+  #   # is requested with invalid values, the response is:
+  #   #
+  #   # Response (422):
+  #   # <errors type="array"><error>First cannot be empty</error></errors>
+  #   #
+  #
+  #   ryan.errors.invalid?(:first)  # => true
+  #   ryan.errors.full_messages     # => ['First cannot be empty']
+  # 
+  # Learn more about Active Resource's validation features in the ActiveResource::Validations documentation.
+  #
+  # === Timeouts
+  #
+  # Active Resource relies on HTTP to access RESTful APIs and as such is inherently susceptible to slow or
+  # unresponsive servers. In such cases, your Active Resource method calls could timeout. You can control the
+  # amount of time before Active Resource times out with the +timeout+ variable.
+  #
+  #   class Person < ActiveResource::Base
+  #     self.site = "http://api.people.com:3000/"
+  #     self.timeout = 5
+  #   end
+  #
+  # This sets the +timeout+ to 5 seconds. You can adjust the +timeout+ to a value suitable for the RESTful API
+  # you are accessing. It is recommended to set this to a reasonably low value to allow your Active Resource
+  # clients (especially if you are using Active Resource in a Rails application) to fail-fast (see
+  # http://en.wikipedia.org/wiki/Fail-fast) rather than cause cascading failures that could incapacitate your
+  # server.
+  #
+  # When a timeout occurs, an ActiveResource::TimeoutError is raised. You should rescue from
+  # ActiveResource::TimeoutError in your Active Resource method calls.
+  #
+  # Internally, Active Resource relies on Ruby's Net::HTTP library to make HTTP requests. Setting +timeout+
+  # sets the <tt>read_timeout</tt> of the internal Net::HTTP instance to the same value. The default
+  # <tt>read_timeout</tt> is 60 seconds on most Ruby implementations.
+  class Base
+    # The logger for diagnosing and tracing Active Resource calls.
+    cattr_accessor :logger

+      # ==== Arguments
+      # The first argument is considered to be the scope of the query.  That is, how many 
+      # resources are returned from the request.  It can be one of the following.
+      #
+      # * <tt>:one</tt> - Returns a single resource.
+      # * <tt>:first</tt> - Returns the first resource found.
+      # * <tt>:all</tt> - Returns every resource that matches the request.
+      # 
+      # ==== Options
+      #
+      # * <tt>:from</tt> - Sets the path or custom method that resources will be fetched from.
+      # * <tt>:params</tt> - Sets query and prefix (nested URL) parameters.

+  #
+  #    POST    /people/new/register.xml # PeopleController.register
+  #    PUT     /people/1/promote.xml    # PeopleController.promote with :id => 1

+module ActiveResource
+  class InvalidRequestError < StandardError; end #:nodoc:
+
+  # 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 letting you know you need to create a new mock for that request.
+  #
+  # ==== Example
+  #   def setup
+  #     @matz  = { :id => 1, :name => "Matz" }.to_xml(:root => "person")
+  #     ActiveResource::HttpMock.respond_to do |mock|
+  #       mock.post   "/people.xml",   {}, @matz, 201, "Location" => "/people/1.xml"
+  #       mock.get    "/people/1.xml", {}, @matz
