+= Ruby OpenID Library Installation
+
+== Rubygems Installation
+
+Rubygems is a tool for installing ruby libraries and their
+dependancies.  If you have rubygems installed, simply:
+
+  gem install ruby-openid
+
+== Manual Installation
+
+Unpack the archive and run setup.rb to install:
+
+ ruby setup.rb
+
+setup.rb installs the library into your system ruby.  If don't want to
+add openid to you system ruby, you may instead add the *lib* directory of
+the extracted tarball to your RUBYLIB environment variable:
+
+  $ export RUBYLIB=${RUBYLIB}:/path/to/ruby-openid/lib
+
+
+== Testing the Installation
+
+Make sure everything installed ok:
+ $> irb
+ irb$> require "openid"
+ => true
+
+Or, if you installed via rubygems:
+
+ $> irb
+ irb$> require "rubygems"
+ => true
+ irb$> require_gem "ruby-openid" 
+ => true
+
+== Run the test suite
+
+Go into the test directory and execute the *runtests.rb* script.
+
+== Next steps
+
+* Run consumer.rb in the examples directory. 
+* Get started writing your own consumer using OpenID::Consumer
+* Write your own server with OpenID::Server
+* Use the OpenIDLoginGenerator!  Read example/README for more info.

+
+      "Object" form shall mean any form resulting from mechanical

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+=Ruby OpenID
+
+A Ruby library for verifying and serving OpenID identities.
+
+==Features
+* Easy to use API for verifying OpenID identites - OpenID::Consumer
+* Support for serving OpenID identites - OpenID::Server
+* Does not depend on underlying web framework
+* Supports multiple storage mechanisms (Filesystem, ActiveRecord, Memory)
+* Example code to help you get started, including:
+  * Ruby on Rails based consumer and server
+  * OpenIDLoginGenerator for quickly getting creating a rails app that uses
+    OpenID for authentication
+  * ActiveRecordOpenIDStore plugin
+* Comprehensive test suite
+* Supports both OpenID 1 and OpenID 2 transparently
+
+==Installing
+Before running the examples or writing your own code you'll need to install
+the library.  See the INSTALL file or use rubygems:
+
+  gem install ruby-openid
+  
+Check the installation:
+  
+  $ irb
+  irb> require 'rubygems'
+  irb> require_gem 'ruby-openid'
+  => true
+
+The library is known to work with Ruby 1.8.4 on Unix, Max OSX and
+Win32.  Examples have been tested with Rails 1.1 and 1.2, and 2.0.
+
+==Getting Started
+The best way to start is to look at the rails_openid example.
+You can run it with:
+ cd examples/rails_openid
+ script/server
+
+If you are writing an OpenID Relying Party, a good place to start is:
+examples/rails_openid/app/controllers/consumer_controller.rb
+
+And if you are writing an OpenID provider:
+examples/rails_openid/app/controllers/server_controller.rb
+
+The library code is quite well documented, so don't be squeamish, and
+look at the library itself if there's anything you don't understand in
+the examples.

+= Upgrading from the OpenID 1.x series library
+
+== Consumer Upgrade
+
+The flow is largely the same, however there are a number of significant 
+changes.  The consumer example is helpful to look at:
+examples/rails_openid/app/controllers/consumer_controller.rb
+
+
+=== Stores
+
+You will need to require the file for the store that you are using.
+For the filesystem store, this is 'openid/stores/filesystem'
+They are also now in modules.  The filesystem store is 
+  OpenID::Store::Filesystem
+The format has changed, and you should remove your old store directory.
+
+The ActiveRecord store ( examples/active_record_openid_store ) still needs
+to be put in a plugin directory for your rails app.  There's a migration
+that needs to be run; examine the README in that directory.
+
+Also, note that the stores now can be garbage collected with the method
+  store.cleanup
+
+
+=== Starting the OpenID transaction
+
+The OpenIDRequest object no longer has status codes.  Instead,
+consumer.begin raises an OpenID::OpenIDError if there is a problem
+initiating the transaction, so you'll want something along the lines of:
+
+  begin
+    openid_request = consumer.begin(params[:openid_identifier])
+  rescue OpenID::OpenIDError => e
+    # display error e
+    return
+  end
+  #success case
+
+Data regarding the OpenID server once lived in
+  openid_request.service
+
+The corresponding object in the 2.0 lib can be retrieved with
+  openid_request.endpoint
+
+Getting the unverified identifier: Where you once had
+  openid_request.identity_url
+you will now want
+  openid_request.endpoint.claimed_id
+which might be different from what you get at the end of the transaction,
+since it is now possible for users to enter their server's url directly.
+
+Arguments on the return_to URL are now verified, so if you want to add
+additional arguments to the return_to url, use
+  openid_request.return_to_args['param'] = value
+
+Generating the redirect is the same as before, but add any extensions
+first.
+
+If you need to set up an SSL certificate authority list for the fetcher,
+use the 'ca_file' attr_accessor on the OpenID::StandardFetcher.  This has
+changed from 'ca_path' in the 1.x.x series library.  That is, set
+OpenID.fetcher.ca_file = '/path/to/ca.list'
+before calling consumer.begin.
+
+=== Requesting Simple Registration Data
+
+You'll need to require the code for the extension
+  require 'openid/extensions/sreg'
+
+The new code for adding an SReg request now looks like:
+
+  sreg_request = OpenID::SReg::Request.new
+  sreg_request.request_fields(['email', 'dob'], true) # required
+  sreg_request.request_fields(['nickname', 'fullname'], false) # optional
+  sreg_request.policy_url = policy_url
+  openid_request.add_extension(sreg_request)
+
+The code for adding other extensions is similar.  Code for the Attribute
+Exchange (AX) and Provider Authentication Policy Extension (PAPE) are
+included with the library, and additional extensions can be implemented
+subclassing OpenID::Extension.
+
+
+=== Completing the transaction
+
+The return_to and its arguments are verified, so you need to pass in
+the base URL and the arguments.  With Rails, the params method mashes
+together parameters from GET, POST, and the path, so you'll need to pull
+off the path "parameters" with something like
+
+  return_to = url_for(:only_path => false, 
+                      :controller => 'openid',
+                      :action => 'complete')
+  parameters = params.reject{|k,v| request.path_parameters[k] }
+  openid_response = consumer.complete(parameters, return_to)
+
+The response still uses the status codes, but they are now namespaced
+slightly differently, for example OpenID::Consumer::SUCCESS
+
+In the case of failure, the error message is now found in
+  openid_response.message
+
+The identifier to display to the user can be found in
+  openid_response.endpoint.display_identifier
+
+The Simple Registration response can be read from the OpenID response
+with
+  sreg_response = OpenID::SReg::Response.from_success_response(openid_response)
+  nickname = sreg_response['nickname']
+  # etc.
+
+
+== Server Upgrade
+
+The server code is mostly the same as before, with the exception of
+extensions.  Also, you must pass in the endpoint URL to the server 
+constructor:
+  @server = OpenID::Server.new(store, server_url)
+
+I recommend looking at 
+examples/rails_openid/app/controllers/server_controller.rb
+for an example of the new way of doing extensions.

+This directory contains several examples that demonstrate use of the
+OpenID library.  Make sure you have properly installed the library
+before running the examples.  These examples are a great place to
+start in integrating OpenID into your application.
+
+==Rails example
+
+The rails_openid contains a fully functional OpenID server and relying
+party, and acts as a starting point for implementing your own
+production rails server.  You'll need the latest version of Ruby on
+Rails installed, and then:
+
+ cd rails_openid
+ ./script/server
+
+Open a web browser to http://localhost:3000/ and follow the instructions.
+
+The relevant code to work from when writing your Rails OpenID Relying
+Party is: 
+  rails_openid/app/controllers/consumer_controller.rb
+If you are working on an OpenID provider, check out
+  rails_openid/app/controllers/server_controller.rb
+
+Since the library and examples are Apache-licensed, don't be shy about 
+copy-and-paste.
+
+==Rails ActiveRecord OpenIDStore plugin
+
+For various reasons you may want or need to deploy your ruby openid
+consumer/server using an SQL based store.  The active_record_openid_store 
+is a plugin that makes using an SQL based store simple.  Follow the
+README inside the plugin's dir for usage.

+=Active Record OpenID Store Plugin
+
+A store is required by an OpenID server and optionally by the consumer
+to store associations, nonces, and auth key information across
+requests and processes.  If rails is distributed across several
+machines, they must must all have access to the same OpenID store
+data, so the FilesystemStore won't do.
+
+This directory contains a plugin for connecting your
+OpenID enabled rails app to an ActiveRecord based OpenID store.
+
+==Install
+
+1) Copy this directory and all it's contents into your
+RAILS_ROOT/vendor/plugins directory.  You structure should look like
+this:
+
+  RAILS_ROOT/vendor/plugins/active_record_openid_store/
+
+2) Copy the migration, XXX_add_open_id_store_to_db.rb to your
+   RAILS_ROOT/db/migrate directory.  Rename the XXX portion of the
+   file to next sequential migration number.
+
+3) Run the migration:
+
+  rake migrate
+
+4) Change your app to use the ActiveRecordOpenIDStore:
+
+  store = ActiveRecordOpenIDStore.new
+  consumer = OpenID::Consumer.new(session, store)
+
+5) That's it! All your OpenID state will now be stored in the database.
+
+==Upgrade
+
+If you are upgrading from the 1.x ActiveRecord store, replace your old
+RAILS_ROOT/vendor/plugins/active_record_openid_store/ directory with
+the new one and run the migration XXX_upgrade_open_id_store.rb.
+
+==What about garbage collection? 
+
+You may garbage collect unused nonces and expired associations using
+the gc instance method of ActiveRecordOpenIDStore.  Hook it up to a
+task in your app's Rakefile like so:
+
+  desc 'GC OpenID store'
+  task :gc_openid_store => :environment do
+    ActiveRecordOpenIDStore.new.cleanup
+  end
+
+Run it by typing:
+
+  rake gc_openid_store

+== Welcome to Rails
+
+Rails is a web-application and persistence framework that includes everything
+needed to create database-backed web-applications according to the
+Model-View-Control pattern of separation. This pattern splits the view (also
+called the presentation) into "dumb" templates that are primarily responsible
+for inserting pre-built data in between HTML tags. The model contains the
+"smart" domain objects (such as Account, Product, Person, Post) that holds all
+the business logic and knows how to persist themselves to a database. The
+controller handles the incoming requests (such as Save New Account, Update
+Product, Show Post) by manipulating the model and directing data to the view.
+
+In Rails, the model is handled by what's called an object-relational mapping
+layer entitled Active Record. This layer allows you to present the data from
+database rows as objects and embellish these data objects with business logic
+methods. You can read more about Active Record in 
+link:files/vendor/rails/activerecord/README.html.
+
+The controller and view are handled by the Action Pack, which handles both
+layers by its two parts: Action View and Action Controller. These two layers
+are bundled in a single package due to their heavy interdependence. This is
+unlike the relationship between the Active Record and Action Pack that is much
+more separate. Each of these packages can be used independently outside of
+Rails.  You can read more about Action Pack in 
+link:files/vendor/rails/actionpack/README.html.
+
+
+== Getting started
+
+1. Run the WEBrick servlet: <tt>ruby script/server</tt> (run with --help for options)
+   ...or if you have lighttpd installed: <tt>ruby script/lighttpd</tt> (it's faster)
+2. Go to http://localhost:3000/ and get "Congratulations, you've put Ruby on Rails!"
+3. Follow the guidelines on the "Congratulations, you've put Ruby on Rails!" screen
+
+
+== Example for Apache conf
+
+  <VirtualHost *:80>
+    ServerName rails
+    DocumentRoot /path/application/public/
+    ErrorLog /path/application/log/server.log
+  
+    <Directory /path/application/public/>
+      Options ExecCGI FollowSymLinks
+      AllowOverride all
+      Allow from all
+      Order allow,deny
+    </Directory>
+  </VirtualHost>
+
+NOTE: Be sure that CGIs can be executed in that directory as well. So ExecCGI
+should be on and ".cgi" should respond. All requests from 127.0.0.1 go
+through CGI, so no Apache restart is necessary for changes. All other requests
+go through FCGI (or mod_ruby), which requires a restart to show changes.
+
+
+== Debugging Rails
+
+Have "tail -f" commands running on both the server.log, production.log, and
+test.log files. Rails will automatically display debugging and runtime
+information to these files. Debugging info will also be shown in the browser
+on requests from 127.0.0.1.
+
+
+== Breakpoints
+
+Breakpoint support is available through the script/breakpointer client. This
+means that you can break out of execution at any point in the code, investigate
+and change the model, AND then resume execution! Example:
+
+  class WeblogController < ActionController::Base
+    def index
+      @posts = Post.find_all
+      breakpoint "Breaking out from the list"
+    end
+  end
+  
+So the controller will accept the action, run the first line, then present you
+with a IRB prompt in the breakpointer window. Here you can do things like:
+
+Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint'
+
+  >> @posts.inspect
+  => "[#<Post:0x14a6be8 @attributes={\"title\"=>nil, \"body\"=>nil, \"id\"=>\"1\"}>, 
+       #<Post:0x14a6620 @attributes={\"title\"=>\"Rails you know!\", \"body\"=>\"Only ten..\", \"id\"=>\"2\"}>]"
+  >> @posts.first.title = "hello from a breakpoint"
+  => "hello from a breakpoint"
+
+...and even better is that you can examine how your runtime objects actually work:
+
+  >> f = @posts.first 
+  => #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>
+  >> f.
+  Display all 152 possibilities? (y or n)
+
+Finally, when you're ready to resume execution, you press CTRL-D
+
+
+== Console
+
+You can interact with the domain model by starting the console through script/console. 
+Here you'll have all parts of the application configured, just like it is when the
+application is running. You can inspect domain models, change values, and save to the
+database. Starting the script without arguments will launch it in the development environment.
+Passing an argument will specify a different environment, like <tt>console production</tt>.
+
+
+== Description of contents
+
+app
+  Holds all the code that's specific to this particular application.
+
+app/controllers
+  Holds controllers that should be named like weblog_controller.rb for
+  automated URL mapping. All controllers should descend from
+  ActionController::Base.
+
+app/models
+  Holds models that should be named like post.rb.
+  Most models will descend from ActiveRecord::Base.
+  
+app/views
+  Holds the template files for the view that should be named like
+  weblog/index.rhtml for the WeblogController#index action. All views use eRuby
+  syntax. This directory can also be used to keep stylesheets, images, and so on
+  that can be symlinked to public.
+  
+app/helpers
+  Holds view helpers that should be named like weblog_helper.rb.
+
+config
+  Configuration files for the Rails environment, the routing map, the database, and other dependencies.
+
+components
+  Self-contained mini-applications that can bundle together controllers, models, and views.
+
+lib
+  Application specific libraries. Basically, any kind of custom code that doesn't
+  belong under controllers, models, or helpers. This directory is in the load path.
+    
+public
+  The directory available for the web server. Contains subdirectories for images, stylesheets,
+  and javascripts. Also contains the dispatchers and the default HTML files.
+
+script
+  Helper scripts for automation and generation.
+
+test
+  Unit and functional tests along with fixtures.
+
+vendor
+  External libraries that the application depends on. Also includes the plugins subdirectory.
+  This directory is in the load path.

+
+<p> Welcome to the Ruby OpenID example.  This code is a starting point
+for developers wishing to implement an OpenID provider or relying
+party.  We've used the <a href="http://rubyonrails.org/">Rails</a>
+platform to demonstrate, but the library code is not Rails specific.</p>
+
+<h2>To use the example provider</h2>
+<p>
+  <ol>
+
+    <li>Enter a username in the form above.  You will be "Logged In"
+    to the server, at which point you may authenticate using an OpenID
+    consumer. Your OpenID URL will be displayed after you log
+    in.<p>The server will automatically create an identity page for
+    you at <%= @base_url %>user/<i>name</i></p></li>
+
+    <li><p>Because WEBrick can only handle one thing at a time, you'll need to
+    run another instance of the example on another port if you want to use
+    a relying party to use with this example provider:</p>
+    <blockquote>
+    <code>script/server --port=3001</code>
+    </blockquote>
+
+    <p>(The RP needs to be able to access the provider, so unless you're
+    running this example on a public IP, you can't use the live example
+    at <a href="http://openidenabled.com/">openidenabled.com</a> on
+    your local provider.)</p>
+    </li>
+
+    <li>Point your browser to this new instance and follow the directions
+    below.</li>
+    <!-- Fun fact: 'url_for :port => 3001' doesn't work very well. -->
+  </ol>
+
+</p>
+
+<h2>To use the example relying party</h2>
+
+<p>Visit <a href="<%= url_for :controller => 'consumer' %>">/consumer</a>
+and enter your OpenID.</p>

+// Autocompleter.Base handles all the autocompletion functionality 
+// that's independent of the data source for autocompletion. This
+// includes drawing the autocompletion menu, observing keyboard
+// and mouse events, and similar.
+//
+// Specific autocompleters need to provide, at the very least, 
+// a getUpdatedChoices function that will be invoked every time
+// the text inside the monitored textbox changes. This method 
+// should get the text for which to provide autocompletion by
+// invoking this.getToken(), NOT by directly accessing
+// this.element.value. This is to allow incremental tokenized
+// autocompletion. Specific auto-completion logic (AJAX, etc)
+// belongs in getUpdatedChoices.
+//
+// Tokenized incremental autocompletion is enabled automatically
+// when an autocompleter is instantiated with the 'tokens' option
+// in the options parameter, e.g.:
+// new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
+// will incrementally autocomplete with a comma as the token.
+// Additionally, ',' in the above example can be replaced with
+// a token array, e.g. { tokens: [',', '\n'] } which
+// enables autocompletion on multiple tokens. This is most 
+// useful when one of the tokens is \n (a newline), as it 
+// allows smart autocompletion after linebreaks.

+// The constructor takes four parameters. The first two are, as usual,

+// The third is the array you want to autocomplete from, and the fourth
+// is the options block.
+//
+// Extra local autocompletion options:
+// - choices - How many autocompletion choices to offer
+//
+// - partialSearch - If false, the autocompleter will match entered
+//                    text only at the beginning of strings in the 
+//                    autocomplete array. Defaults to true, which will
+//                    match text at the beginning of any *word* in the
+//                    strings in the autocomplete array. If you want to
+//                    search anywhere in the string, additionally set
+//                    the option fullSearch to true (default: off).
+//
+// - fullSsearch - Search anywhere in autocomplete array strings.
+//
+// - partialChars - How many characters to enter before triggering
+//                   a partial match (unlike minChars, which defines
+//                   how many characters are required to do any match
+//                   at all). Defaults to 2.
+//
+// - ignoreCase - Whether to ignore case when autocompleting.
+//                 Defaults to true.
+//
+// It's possible to pass in a custom function as the 'selector' 
+// option, if you prefer to write your own autocompletion logic.

+module OpenID
+  # OpenID support for Relying Parties (aka Consumers).
+  #
+  # This module documents the main interface with the OpenID consumer
+  # library.  The only part of the library which has to be used and
+  # isn't documented in full here is the store required to create an
+  # Consumer instance.
+  #
+  # = OVERVIEW
+  #
+  # The OpenID identity verification process most commonly uses the
+  # following steps, as visible to the user of this library:
+  #
+  # 1. The user enters their OpenID into a field on the consumer's
+  #    site, and hits a login button.
+  #
+  # 2. The consumer site discovers the user's OpenID provider using
+  #    the Yadis protocol.
+  #
+  # 3. The consumer site sends the browser a redirect to the OpenID
+  #    provider.  This is the authentication request as described in
+  #    the OpenID specification.
+  #
+  # 4. The OpenID provider's site sends the browser a redirect back to
+  #    the consumer site.  This redirect contains the provider's
+  #    response to the authentication request.
+  #
+  # The most important part of the flow to note is the consumer's site
+  # must handle two separate HTTP requests in order to perform the
+  # full identity check.
+  #
+  # = LIBRARY DESIGN
+  #
+  # This consumer library is designed with that flow in mind.  The
+  # goal is to make it as easy as possible to perform the above steps
+  # securely.
+  #
+  # At a high level, there are two important parts in the consumer
+  # library.  The first important part is this module, which contains
+  # the interface to actually use this library.  The second is
+  # openid/store/interface.rb, which describes the interface to use if
+  # you need to create a custom method for storing the state this
+  # library needs to maintain between requests.
+  #
+  # In general, the second part is less important for users of the
+  # library to know about, as several implementations are provided
+  # which cover a wide variety of situations in which consumers may
+  # use the library.
+  #
+  # The Consumer class has methods corresponding to the actions
+  # necessary in each of steps 2, 3, and 4 described in the overview.
+  # Use of this library should be as easy as creating an Consumer
+  # instance and calling the methods appropriate for the action the
+  # site wants to take.
+  #
+  # This library automatically detects which version of the OpenID
+  # protocol should be used for a transaction and constructs the
+  # proper requests and responses.  Users of this library do not need
+  # to worry about supporting multiple protocol versions; the library
+  # supports them implicitly.  Depending on the version of the
+  # protocol in use, the OpenID transaction may be more secure.  See
+  # the OpenID specifications for more information.
+  #
+  # = SESSIONS, STORES, AND STATELESS MODE
+  #
+  # The Consumer object keeps track of two types of state:
+  #
+  # 1. State of the user's current authentication attempt.  Things
+  #    like the identity URL, the list of endpoints discovered for
+  #    that URL, and in case where some endpoints are unreachable, the
+  #    list of endpoints already tried.  This state needs to be held
+  #    from Consumer.begin() to Consumer.complete(), but it is only
+  #    applicable to a single session with a single user agent, and at
+  #    the end of the authentication process (i.e. when an OP replies
+  #    with either <tt>id_res</tt>. or <tt>cancel</tt> it may be
+  #    discarded.
+  #
+  # 2. State of relationships with servers, i.e. shared secrets
+  #    (associations) with servers and nonces seen on signed messages.
+  #    This information should persist from one session to the next
+  #    and should not be bound to a particular user-agent.
+  #
+  # These two types of storage are reflected in the first two
+  # arguments of Consumer's constructor, <tt>session</tt> and
+  # <tt>store</tt>.  <tt>session</tt> is a dict-like object and we
+  # hope your web framework provides you with one of these bound to
+  # the user agent.  <tt>store</tt> is an instance of Store.
+  #
+  # Since the store does hold secrets shared between your application
+  # and the OpenID provider, you should be careful about how you use
+  # it in a shared hosting environment.  If the filesystem or database
+  # permissions of your web host allow strangers to read from them, do
+  # not store your data there!  If you have no safe place to store
+  # your data, construct your consumer with nil for the store, and it
+  # will operate only in stateless mode.  Stateless mode may be
+  # slower, put more load on the OpenID provider, and trusts the
+  # provider to keep you safe from replay attacks.
+  #
+  # Several store implementation are provided, and the interface is
+  # fully documented so that custom stores can be used as well.  See
+  # the documentation for the Consumer class for more information on
+  # the interface for stores.  The implementations that are provided
+  # allow the consumer site to store the necessary data in several
+  # different ways, including several SQL databases and normal files
+  # on disk.
+  #
+  # = IMMEDIATE MODE
+  #
+  # In the flow described above, the user may need to confirm to the
+  # OpenID provider that it's ok to disclose his or her identity.  The
+  # provider may draw pages asking for information from the user
+  # before it redirects the browser back to the consumer's site.  This
+  # is generally transparent to the consumer site, so it is typically
+  # ignored as an implementation detail.
+  #
+  # There can be times, however, where the consumer site wants to get
+  # a response immediately.  When this is the case, the consumer can
+  # put the library in immediate mode.  In immediate mode, there is an
+  # extra response possible from the server, which is essentially the
+  # server reporting that it doesn't have enough information to answer
+  # the question yet.
+  #
+  # = USING THIS LIBRARY
+  #
+  # Integrating this library into an application is usually a
+  # relatively straightforward process.  The process should basically
+  # follow this plan:
+  #
+  # Add an OpenID login field somewhere on your site.  When an OpenID
+  # is entered in that field and the form is submitted, it should make
+  # a request to the your site which includes that OpenID URL.
+  #
+  # First, the application should instantiate a Consumer with a
+  # session for per-user state and store for shared state using the
+  # store of choice.
+  #
+  # Next, the application should call the <tt>begin</tt> method of
+  # Consumer instance.  This method takes the OpenID URL as entered by
+  # the user.  The <tt>begin</tt> method returns a CheckIDRequest
+  # object.
+  #
+  # Next, the application should call the redirect_url method on the
+  # CheckIDRequest object.  The parameter <tt>return_to</tt> is the
+  # URL that the OpenID server will send the user back to after
+  # attempting to verify his or her identity.  The <tt>realm</tt>
+  # parameter is the URL (or URL pattern) that identifies your web
+  # site to the user when he or she is authorizing it.  Send a
+  # redirect to the resulting URL to the user's browser.
+  #
+  # That's the first half of the authentication process.  The second
+  # half of the process is done after the user's OpenID Provider sends
+  # the user's browser a redirect back to your site to complete their
+  # login.
+  #
+  # When that happens, the user will contact your site at the URL
+  # given as the <tt>return_to</tt> URL to the redirect_url call made
+  # above.  The request will have several query parameters added to
+  # the URL by the OpenID provider as the information necessary to
+  # finish the request.
+  #
+  # Get a Consumer instance with the same session and store as before
+  # and call its complete() method, passing in all the received query
+  # arguments and URL currently being handled.
+  #
+  # There are multiple possible return types possible from that
+  # method. These indicate the whether or not the login was
+  # successful, and include any additional information appropriate for
+  # their type.
