+== 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 local array autocompleter. Used when you'd prefer to
+// inject an array of autocompletion options into the page, rather
+// than sending out Ajax queries, which can be quite slow sometimes.
+//
+// The constructor takes four parameters. The first two are, as usual,
+// the id of the monitored textbox, and id of the autocompletion menu.
+// 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.
+// In that case, the other options above will not apply unless
+// you support them.
