+	== Welcome to Rails
+
+	Rails is a web-application framework that includes everything needed to create
+	database-backed web applications according to the Model-View-Control pattern.
+
+	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. At the command prompt, create a new Rails application:
+	<tt>rails new myapp</tt> (where <tt>myapp</tt> is the application name)
+
+	2. Change directory to <tt>myapp</tt> and start the web server:
+	<tt>cd myapp; rails server</tt> (run with --help for options)
+
+	3. Go to http://localhost:3000/ and you'll see:
+	"Welcome aboard: You're riding Ruby on Rails!"
+
+	4. Follow the guidelines to start developing your application. You can find
+	the following resources handy:
+
+	* The Getting Started Guide: http://guides.rubyonrails.org/getting_started.html
+	* Ruby on Rails Tutorial Book: http://www.railstutorial.org/
+
+
+	== Debugging Rails
+
+	Sometimes your application goes wrong. Fortunately there are a lot of tools that
+	will help you debug it and get it back on the rails.
+
+	First area to check is the application log files. Have "tail -f" commands
+	running on the server.log and development.log. 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.
+
+	You can also log your own messages directly into the log file from your code
+	using the Ruby logger class from inside your controllers. Example:
+
+	class WeblogController < ActionController::Base
+	def destroy
+	@weblog = Weblog.find(params[:id])
+	@weblog.destroy
+	logger.info("#{Time.now} Destroyed Weblog ID ##{@weblog.id}!")
+	end
+	end
+
+	The result will be a message in your log file along the lines of:
+
+	Mon Oct 08 14:22:29 +1000 2007 Destroyed Weblog ID #1!
+
+	More information on how to use the logger is at http://www.ruby-doc.org/core/
+
+	Also, Ruby documentation can be found at http://www.ruby-lang.org/. There are
+	several books available online as well:
+
+	* Programming Ruby: http://www.ruby-doc.org/docs/ProgrammingRuby/ (Pickaxe)
+	* Learn to Program: http://pine.fm/LearnToProgram/ (a beginners guide)
+
+	These two books will bring you up to speed on the Ruby language and also on
+	programming in general.
+
+
+	== Debugger
+
+	Debugger support is available through the debugger command when you start your
+	Mongrel or WEBrick server with --debugger. This means that you can break out of
+	execution at any point in the code, investigate and change the model, and then,
+	resume execution! You need to install ruby-debug to run the server in debugging
+	mode. With gems, use <tt>sudo gem install ruby-debug</tt>. Example:
+
+	class WeblogController < ActionController::Base
+	def index
+	@posts = Post.find(:all)
+	debugger
+	end
+	end
+
+	So the controller will accept the action, run the first line, then present you
+	with a IRB prompt in the server window. Here you can do things like:
+
+	>> @posts.inspect
+	=> "[#<Post:0x14a6be8
+	@attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>,
+	#<Post:0x14a6620
+	@attributes={"title"=>"Rails", "body"=>"Only ten..", "id"=>"2"}>]"
+	>> @posts.first.title = "hello from a debugger"
+	=> "hello from a debugger"
+
+	...and even better, 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 can enter "cont".
+
+
+	== Console
+
+	The console is a Ruby shell, which allows you to interact with your
+	application's domain model. 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.
+
+	To start the console, run <tt>rails console</tt> from the application
+	directory.
+
+	Options:
+
+	* Passing the <tt>-s, --sandbox</tt> argument will rollback any modifications
+	made to the database.
+	* Passing an environment name as an argument will load the corresponding
+	environment. Example: <tt>rails console production</tt>.
+
+	To reload your controllers and models after launching the console run
+	<tt>reload!</tt>
+
+	More information about irb can be found at:
+	link:http://www.rubycentral.com/pickaxe/irb.html
+
+
+	== dbconsole
+
+	You can go to the command line of your database directly through <tt>rails
+	dbconsole</tt>. You would be connected to the database with the credentials
+	defined in database.yml. Starting the script without arguments will connect you
+	to the development database. Passing an argument will connect you to a different
+	database, like <tt>rails dbconsole production</tt>. Currently works for MySQL,
+	PostgreSQL and SQLite 3.

+
+	app
+	Holds all the code that's specific to this particular application.
+
+	app/controllers
+	Holds controllers that should be named like weblogs_controller.rb for
+	automated URL mapping. All controllers should descend from
+	ApplicationController which itself descends from ActionController::Base.
+
+	app/models
+	Holds models that should be named like post.rb. Models descend from
+	ActiveRecord::Base by default.
+
+	app/views
+	Holds the template files for the view that should be named like
+	weblogs/index.html.erb for the WeblogsController#index action. All views use
+	eRuby syntax by default.
+
+	app/views/layouts
+	Holds the template files for layouts to be used with views. This models the
+	common header/footer method of wrapping views. In your views, define a layout
+	using the <tt>layout :default</tt> and create a file named default.html.erb.
+	Inside default.html.erb, call <% yield %> to render the view using this
+	layout.
+
+	app/helpers
+	Holds view helpers that should be named like weblogs_helper.rb. These are
+	generated for you automatically when using generators for controllers.
+	Helpers can be used to wrap functionality for your views into methods.
+
+	config
+	Configuration files for the Rails environment, the routing map, the database,
+	and other dependencies.
+
+	db
+	Contains the database schema in schema.rb. db/migrate contains all the
+	sequence of Migrations for your schema.
+
+	doc
+	This directory is where your application documentation will be stored when
+	generated using <tt>rake doc:app</tt>
+
+	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. This should be set as the DOCUMENT_ROOT of your web
+	server.
+
+	script
+	Helper scripts for automation and generation.
+
+	test
+	Unit and functional tests along with fixtures. When using the rails generate
+	command, template test files will be generated for you and placed in this
+	directory.
+
+	vendor
+	External libraries that the application depends on. Also includes the plugins
+	subdirectory. If the app has frozen rails, those gems also go here, under
+	vendor/rails/. This directory is in the load path.

+	// 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.

+	// - partialSearch - If false, the autocompleter will match entered

+	// strings in the autocomplete array. If you want to

+	//
+	// - 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.
