+    # as well as a rack method of session management.
+    #
+    # The ruby-openid home page is at http://openidenabled.com/ruby-openid/.
+    #
+    # The OpenID specifications can be found at
+    # http://openid.net/specs/openid-authentication-1_1.html
+    # and
+    # http://openid.net/specs/openid-authentication-2_0.html. Documentation
+    # for published OpenID extensions and related topics can be found at

+    #
+    # It is recommended to read through the OpenID spec, as well as
+    # ruby-openid's documentation, to understand what exactly goes on. However
+    # a setup as simple as the presented examples is enough to provide
+    # Consumer functionality.
+    #
+    # This library strongly intends to utilize the OpenID 2.0 features of the
+    # ruby-openid library, which provides OpenID 1.0 compatiblity.
+    #
+    # NOTE: Due to the amount of data that this library stores in the

+      # Required for ruby-openid
+      ValidStatus = [:success, :setup_needed, :cancel, :failure]
+
+      # = Arguments
+      #
+      # The first argument is the realm, identifying the site they are trusting
+      # with their identity. This is required, also treated as the trust_root
+      # in OpenID 1.x exchanges.
+      #
+      # The optional second argument is a hash of options.
+      #
+      # == Options
+      #
+      # <tt>:return_to</tt> defines the url to return to after the client
+      # authenticates with the openid service provider. This url should point
+      # to where Rack::Auth::OpenID is mounted. If <tt>:return_to</tt> is not
+      # provided, return_to will be the current url which allows flexibility
+      # with caveats.
+      #
+      # <tt>:session_key</tt> defines the key to the session hash in the env.
+      # It defaults to 'rack.session'.
+      #
+      # <tt>:openid_param</tt> defines at what key in the request parameters to
+      # find the identifier to resolve. As per the 2.0 spec, the default is
+      # 'openid_identifier'.
+      #
+      # <tt>:store</tt> defined what OpenID Store to use for persistant
+      # information. By default a Store::Memory will be used.
+      #
+      # <tt>:immediate</tt> as true will make initial requests to be of an
+      # immediate type. This is false by default. See OpenID specification
+      # documentation.
+      #
+      # <tt>:extensions</tt> should be a hash of openid extension
+      # implementations. The key should be the extension main module, the value
+      # should be an array of arguments for extension::Request.new.
+      # The hash is iterated over and passed to #add_extension for processing.
+      # Please see #add_extension for further documentation.
+      #
+      # == Examples
+      #
+      #   simple_oid = OpenID.new('http://mysite.com/')
+      #
+      #   return_oid = OpenID.new('http://mysite.com/', {
+      #     :return_to => 'http://mysite.com/openid'
+      #   })
+      #
+      #   complex_oid = OpenID.new('http://mysite.com/',
+      #     :immediate => true,
+      #     :extensions => {
+      #       ::OpenID::SReg => [['email'],['nickname']]
+      #     }
+      #   )
+      #
+      # = Advanced
+      #
+      # Most of the functionality of this library is encapsulated such that
+      # expansion and overriding functions isn't difficult nor tricky.
+      # Alternately, to avoid opening up singleton objects or subclassing, a
+      # wrapper rack middleware can be composed to act upon Auth::OpenID's
+      # responses. See #check and #finish for locations of pertinent data.
+      #
+      # == Responses
+      #
+      # To change the responses that Auth::OpenID returns, override the methods
+      # #redirect, #bad_request, #unauthorized, #access_denied, and
+      # #foreign_server_failure.
+      #
+      # Additionally #confirm_post_params is used when the URI would exceed
+      # length limits on a GET request when doing the initial verification
+      # request.
+      #
+      # == Processing
+      #
+      # To change methods of processing completed transactions, override the
+      # methods #success, #setup_needed, #cancel, and #failure. Please ensure
+      # the returned object is a rack compatible response.
+      #
+      # The first argument is an OpenID::Response, the second is a
+      # Rack::Request of the current request, the last is the hash used in
+      # ruby-openid handling, which can be found manually at
+      # env['rack.session'][:openid].
+      #
+      # This is useful if you wanted to expand the processing done, such as
+      # setting up user accounts.

+      ## (adopted from PEP333), except when they'd be empty, but see
+      ## below.
+
+      ## <tt>REQUEST_METHOD</tt>:: The HTTP request method, such as
+      ##                           "GET" or "POST". This cannot ever
+      ##                           be an empty string, and so is
+      ##                           always required.
+
+      ## <tt>SCRIPT_NAME</tt>:: The initial portion of the request
+      ##                        URL's "path" that corresponds to the
+      ##                        application object, so that the
+      ##                        application knows its virtual
+      ##                        "location". This may be an empty
+      ##                        string, if the application corresponds
+      ##                        to the "root" of the server.
+
+      ## <tt>PATH_INFO</tt>:: The remainder of the request URL's
+      ##                      "path", designating the virtual
+      ##                      "location" of the request's target
+      ##                      within the application. This may be an
+      ##                      empty string, if the request URL targets
+      ##                      the application root and does not have a
+      ##                      trailing slash. This value may be
+      ##                      percent-encoded when I originating from
+      ##                      a URL.
+
+      ## <tt>QUERY_STRING</tt>:: The portion of the request URL that
+      ##                         follows the <tt>?</tt>, if any. May be
+      ##                         empty, but is always required!
+
+      ## <tt>SERVER_NAME</tt>, <tt>SERVER_PORT</tt>:: When combined with <tt>SCRIPT_NAME</tt> and <tt>PATH_INFO</tt>, these variables can be used to complete the URL. Note, however, that <tt>HTTP_HOST</tt>, if present, should be used in preference to <tt>SERVER_NAME</tt> for reconstructing the request URL.  <tt>SERVER_NAME</tt> and <tt>SERVER_PORT</tt> can never be empty strings, and so are always required.
+
+      ## <tt>HTTP_</tt> Variables:: Variables corresponding to the
+      ##                            client-supplied HTTP request
+      ##                            headers (i.e., variables whose
+      ##                            names begin with <tt>HTTP_</tt>). The
+      ##                            presence or absence of these
+      ##                            variables should correspond with
+      ##                            the presence or absence of the
+      ##                            appropriate HTTP header in the
+      ##                            request.
+
+      ## In addition to this, the Rack environment must include these
+      ## Rack-specific variables:
+
+      ## <tt>rack.version</tt>:: The Array [1,0], representing this version of Rack.
+      ## <tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the request URL.
+      ## <tt>rack.input</tt>:: See below, the input stream.
+      ## <tt>rack.errors</tt>:: See below, the error stream.
+      ## <tt>rack.multithread</tt>:: true if the application object may be simultaneously invoked by another thread in the same process, false otherwise.
+      ## <tt>rack.multiprocess</tt>:: true if an equivalent application object may be simultaneously invoked by another process, false otherwise.
+      ## <tt>rack.run_once</tt>:: true if the server expects (but does not guarantee!) that the application will only be invoked this one time during the life of its containing process. Normally, this will only be true for a server based on CGI (or something similar).
+      ##
+
+      ## Additional environment specifications have approved to
+      ## standardized middleware APIs.  None of these are required to
+      ## be implemented by the server.
+
+      ## <tt>rack.session</tt>:: A hash like interface for storing request session data.
+      ##                         The store must implement:
+      if session = env['rack.session']
