+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/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.  
+  # 
+  # == 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 create 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.
+  # 
+  #   Person.new(:name => 'Ryan).post(:register)
+  #   # => { :id => 1, :name => 'Ryan', :position => 'Clerk' }
+  #
+  #   Person.find(1).put(:promote, :position => 'Manager')
+  #   # => { :id => 1, :name => 'Ryan', :position => 'Manager' }
+  # 
+  # For more information on creating and 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 +site+ variable of the Active Resource class you need to authenticate.
+  # 
+  #   class Person < ActiveResource::Base
+  #     self.site = "http://ryan:password@api.people.com:3000/"
+  #   end
+  # 
+  # For obvious security reasons, it is probably best if such services are available 
+  # over HTTPS.
+  # 
+  # == 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 +404+ (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) # => Raises ActiveResource::ResourceNotFound
+  #   # => Response = 404
+  # 
+  # +404+ is just one of the HTTP error response codes that ActiveResource 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 +422+ and an XML representation of the validation errors.  The save operation will 
+  # then fail (with a +false+ 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.

+# A module to support custom REST methods and sub-resources, allowing you to break out
+# of the "default" REST methods with your own custom resource requests.  For example, 
+# say you use Rails to expose a REST service and configure your routes with:
+#
+#    map.resources :people, :new => { :register => :post },
+#                           :element => { :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.
+#
+#   class Person < ActiveResource::Base
+#     self.site = "http://37s.sunrise.i:3000"
+#   end
+#
+#   Person.new(:name => 'Ryan).post(:register)  # POST /people/new/register.xml
+#   # => { :id => 1, :name => 'Ryan' }
+#
+#   Person.find(1).put(:promote, :position => 'Manager') # PUT /people/1/promote.xml
+#   Person.find(1).delete(:deactivate) # DELETE /people/1/deactivate.xml
+#
+#   Person.get(:active)  # GET /people/active.xml
