-module ActionController
-  # == Routing
-  #
-  # The routing module provides URL rewriting in native Ruby. It's a way to
-  # redirect incoming requests to controllers and actions. This replaces
-  # mod_rewrite rules. Best of all, Rails' Routing works with any web server.
-  # Routes are defined in <tt>config/routes.rb</tt>.
-  #
-  # Consider the following route, installed by Rails when you generate your
-  # application:
-  #
-  #   map.connect ':controller/:action/:id'
-  #
-  # This route states that it expects requests to consist of a
-  # <tt>:controller</tt> followed by an <tt>:action</tt> that in turn is fed
-  # some <tt>:id</tt>.
-  #
-  # Suppose you get an incoming request for <tt>/blog/edit/22</tt>, you'll end up
-  # with:
-  #
-  #   params = { :controller => 'blog',
-  #              :action     => 'edit',
-  #              :id         => '22'
-  #           }
-  #
-  # Think of creating routes as drawing a map for your requests. The map tells
-  # them where to go based on some predefined pattern:
-  #
-  #   ActionController::Routing::Routes.draw do |map|
-  #     Pattern 1 tells some request to go to one place
-  #     Pattern 2 tell them to go to another
-  #     ...
-  #   end
-  #
-  # The following symbols are special:
-  #
-  #   :controller maps to your controller name
-  #   :action     maps to an action with your controllers
-  #
-  # Other names simply map to a parameter as in the case of <tt>:id</tt>.
-  #
-  # == Route priority
-  #
-  # Not all routes are created equally. Routes have priority defined by the
-  # order of appearance of the routes in the <tt>config/routes.rb</tt> file. The priority goes
-  # from top to bottom. The last route in that file is at the lowest priority
-  # and will be applied last. If no route matches, 404 is returned.
-  #
-  # Within blocks, the empty pattern is at the highest priority.
-  # In practice this works out nicely:
-  #
-  #   ActionController::Routing::Routes.draw do |map|
-  #     map.with_options :controller => 'blog' do |blog|
-  #       blog.show '',  :action => 'list'
-  #     end
-  #     map.connect ':controller/:action/:view'
-  #   end
-  #
-  # In this case, invoking blog controller (with an URL like '/blog/')
-  # without parameters will activate the 'list' action by default.
-  #
-  # == Defaults routes and default parameters
-  #
-  # Setting a default route is straightforward in Rails - you simply append a
-  # Hash at the end of your mapping to set any default parameters.
-  #
-  # Example:
-  #
-  #   ActionController::Routing:Routes.draw do |map|
-  #     map.connect ':controller/:action/:id', :controller => 'blog'
-  #   end
-  #
-  # This sets up +blog+ as the default controller if no other is specified.
-  # This means visiting '/' would invoke the blog controller.
-  #
-  # More formally, you can include arbitrary parameters in the route, thus:
-  #
-  #   map.connect ':controller/:action/:id', :action => 'show', :page => 'Dashboard'
-  #
-  # This will pass the :page parameter to all incoming requests that match this route.
-  #
-  # Note: The default routes, as provided by the Rails generator, make all actions in every
-  # controller accessible via GET requests. You should consider removing them or commenting
-  # them out if you're using named routes and resources.
-  #
-  # == Named routes
-  #
-  # Routes can be named with the syntax <tt>map.name_of_route options</tt>,
-  # allowing for easy reference within your source as +name_of_route_url+
-  # for the full URL and +name_of_route_path+ for the URI path.
-  #
-  # Example:
-  #
-  #   # In routes.rb
-  #   map.login 'login', :controller => 'accounts', :action => 'login'
-  #
-  #   # With render, redirect_to, tests, etc.
-  #   redirect_to login_url
-  #
-  # Arguments can be passed as well.
-  #
-  #   redirect_to show_item_path(:id => 25)
-  #
-  # Use <tt>map.root</tt> as a shorthand to name a route for the root path "".
-  #
-  #   # In routes.rb
-  #   map.root :controller => 'blogs'
-  #
-  #   # would recognize http://www.example.com/ as
-  #   params = { :controller => 'blogs', :action => 'index' }
-  #
-  #   # and provide these named routes
-  #   root_url   # => 'http://www.example.com/'
-  #   root_path  # => ''
-  #
-  # You can also specify an already-defined named route in your <tt>map.root</tt> call:
-  #
-  #   # In routes.rb
-  #   map.new_session :controller => 'sessions', :action => 'new'
-  #   map.root :new_session
-  #
-  # Note: when using +with_options+, the route is simply named after the
-  # method you call on the block parameter rather than map.
-  #
-  #   # In routes.rb
-  #   map.with_options :controller => 'blog' do |blog|
-  #     blog.show    '',            :action  => 'list'
-  #     blog.delete  'delete/:id',  :action  => 'delete'
-  #     blog.edit    'edit/:id',    :action  => 'edit'
-  #   end
-  #
-  #   # provides named routes for show, delete, and edit
-  #   link_to @article.title, show_path(:id => @article.id)
-  #
-  # == Pretty URLs
-  #
-  # Routes can generate pretty URLs. For example:
-  #
-  #   map.connect 'articles/:year/:month/:day',
-  #               :controller => 'articles',
-  #               :action     => 'find_by_date',
-  #               :year       => /\d{4}/,
-  #               :month      => /\d{1,2}/,
-  #               :day        => /\d{1,2}/
-  #
-  # Using the route above, the URL "http://localhost:3000/articles/2005/11/06"
-  # maps to
-  #
-  #   params = {:year => '2005', :month => '11', :day => '06'}
-  #
-  # == Regular Expressions and parameters
-  # You can specify a regular expression to define a format for a parameter.
-  #
-  #   map.geocode 'geocode/:postalcode', :controller => 'geocode',
-  #               :action => 'show', :postalcode => /\d{5}(-\d{4})?/
-  #
-  # or, more formally:
-  #
-  #   map.geocode 'geocode/:postalcode', :controller => 'geocode',
-  #               :action => 'show', :requirements => { :postalcode => /\d{5}(-\d{4})?/ }
-  #
-  # Formats can include the 'ignorecase' and 'extended syntax' regular
-  # expression modifiers:
-  #
-  #   map.geocode 'geocode/:postalcode', :controller => 'geocode',
-  #               :action => 'show', :postalcode => /hx\d\d\s\d[a-z]{2}/i
-  #
-  #   map.geocode 'geocode/:postalcode', :controller => 'geocode',
-  #               :action => 'show',:requirements => {
-  #                 :postalcode => /# Postcode format
-  #                                 \d{5} #Prefix
-  #                                 (-\d{4})? #Suffix
-  #                                 /x
-  #               }
-  #
-  # Using the multiline match modifier will raise an ArgumentError.
-  # Encoding regular expression modifiers are silently ignored. The
-  # match will always use the default encoding or ASCII.
-  #
-  # == Route globbing
-  #
-  # Specifying <tt>*[string]</tt> as part of a rule like:
-  #
-  #   map.connect '*path' , :controller => 'blog' , :action => 'unrecognized?'
-  #
-  # will glob all remaining parts of the route that were not recognized earlier.
-  # The globbed values are in <tt>params[:path]</tt> as an array of path segments.
-  #
-  # == Route conditions
-  #
-  # With conditions you can define restrictions on routes. Currently the only valid condition is <tt>:method</tt>.
-  #
-  # * <tt>:method</tt> - Allows you to specify which method can access the route. Possible values are <tt>:post</tt>,
-  #   <tt>:get</tt>, <tt>:put</tt>, <tt>:delete</tt> and <tt>:any</tt>. The default value is <tt>:any</tt>,
-  #   <tt>:any</tt> means that any method can access the route.
-  #
-  # Example:
-  #
-  #   map.connect 'post/:id', :controller => 'posts', :action => 'show',
-  #               :conditions => { :method => :get }
-  #   map.connect 'post/:id', :controller => 'posts', :action => 'create_comment',
-  #               :conditions => { :method => :post }
-  #
-  # Now, if you POST to <tt>/posts/:id</tt>, it will route to the <tt>create_comment</tt> action. A GET on the same
-  # URL will route to the <tt>show</tt> action.
-  #
-  # == Reloading routes
-  #
-  # You can reload routes if you feel you must:
-  #
-  #   ActionController::Routing::Routes.reload
-  #
-  # This will clear all named routes and reload routes.rb if the file has been modified from
-  # last load. To absolutely force reloading, use <tt>reload!</tt>.
-  #
-  # == Testing Routes
-  #
-  # The two main methods for testing your routes:
-  #
-  # === +assert_routing+
-  #
-  #   def test_movie_route_properly_splits
-  #    opts = {:controller => "plugin", :action => "checkout", :id => "2"}
-  #    assert_routing "plugin/checkout/2", opts
-  #   end
-  #
-  # +assert_routing+ lets you test whether or not the route properly resolves into options.
-  #
-  # === +assert_recognizes+
-  #
-  #   def test_route_has_options
-  #    opts = {:controller => "plugin", :action => "show", :id => "12"}
-  #    assert_recognizes opts, "/plugins/show/12"
-  #   end
-  #
-  # Note the subtle difference between the two: +assert_routing+ tests that
-  # a URL fits options while +assert_recognizes+ tests that a URL
-  # breaks into parameters properly.
-  #
-  # In tests you can simply pass the URL or named route to +get+ or +post+.
-  #
-  #   def send_to_jail
-  #     get '/jail'
-  #     assert_response :success
-  #     assert_template "jail/front"
-  #   end
-  #
-  #   def goes_to_login
-  #     get login_url
-  #     #...
-  #   end

-module ActionController
-  # == Overview
-  #
-  # ActionController::Resources are a way of defining RESTful \resources.  A RESTful \resource, in basic terms,
-  # is something that can be pointed at and it will respond with a representation of the data requested.
-  # In real terms this could mean a user with a browser requests an HTML page, or that a desktop application
-  # requests XML data.
-  #
-  # RESTful design is based on the assumption that there are four generic verbs that a user of an
-  # application can request from a \resource (the noun).
-  #
-  # \Resources can be requested using four basic HTTP verbs (GET, POST, PUT, DELETE), the method used
-  # denotes the type of action that should take place.
-  #
-  # === The Different Methods and their Usage
-  #
-  # * GET    - Requests for a \resource, no saving or editing of a \resource should occur in a GET request.
-  # * POST   - Creation of \resources.
-  # * PUT    - Editing of attributes on a \resource.
-  # * DELETE - Deletion of a \resource.
-  #
-  # === Examples
-  #
-  #   # A GET request on the Posts resource is asking for all Posts
-  #   GET /posts
-  #
-  #   # A GET request on a single Post resource is asking for that particular Post
-  #   GET /posts/1
-  #
-  #   # A POST request on the Posts resource is asking for a Post to be created with the supplied details
-  #   POST /posts # with => { :post => { :title => "My Whizzy New Post", :body => "I've got a brand new combine harvester" } }
-  #
-  #   # A PUT request on a single Post resource is asking for a Post to be updated
-  #   PUT /posts # with => { :id => 1, :post => { :title => "Changed Whizzy Title" } }
-  #
-  #   # A DELETE request on a single Post resource is asking for it to be deleted
-  #   DELETE /posts # with => { :id => 1 }
-  #
-  # By using the REST convention, users of our application can assume certain things about how the data
-  # is requested and how it is returned.  Rails simplifies the routing part of RESTful design by
-  # supplying you with methods to create them in your routes.rb file.

-    #

-    #
-    # Along with the routes themselves, +resources+ generates named routes for use in
-    # controllers and views. <tt>map.resources :messages</tt> produces the following named routes and helpers:
-    #
-    #   Named Route   Helpers
-    #   ============  =====================================================
-    #   messages      messages_url, hash_for_messages_url,
-    #                 messages_path, hash_for_messages_path
-    #
-    #   message       message_url(id), hash_for_message_url(id),
-    #                 message_path(id), hash_for_message_path(id)
-    #
-    #   new_message   new_message_url, hash_for_new_message_url,
-    #                 new_message_path, hash_for_new_message_path
-    #
-    #   edit_message  edit_message_url(id), hash_for_edit_message_url(id),
-    #                 edit_message_path(id), hash_for_edit_message_path(id)
-    #
-    # You can use these helpers instead of +url_for+ or methods that take +url_for+ parameters. For example:
-    #
-    #   redirect_to :controller => 'messages', :action => 'index'
-    #   # and
-    #   <%= link_to "edit this message", :controller => 'messages', :action => 'edit', :id => @message.id %>
-    #
-    # now become:
-    #
-    #   redirect_to messages_url
-    #   # and
-    #   <%= link_to "edit this message", edit_message_url(@message) # calls @message.id automatically
-    #
-    # Since web browsers don't support the PUT and DELETE verbs, you will need to add a parameter '_method' to your
-    # form tags. The form helpers make this a little easier. For an update form with a <tt>@message</tt> object:
-    #
-    #   <%= form_tag message_path(@message), :method => :put %>
-    #
-    # or
-    #
-    #   <% form_for :message, @message, :url => message_path(@message), :html => {:method => :put} do |f| %>
-    #
-    # or
-    #
-    #   <% form_for @message do |f| %>
-    #
-    # which takes into account whether <tt>@message</tt> is a new record or not and generates the
-    # path and method accordingly.
-    #
-    # The +resources+ method accepts the following options to customize the resulting routes:
-    # * <tt>:collection</tt> - Add named routes for other actions that operate on the collection.
-    #   Takes a hash of <tt>#{action} => #{method}</tt>, where method is <tt>:get</tt>/<tt>:post</tt>/<tt>:put</tt>/<tt>:delete</tt>,
-    #   an array of any of the previous, or <tt>:any</tt> if the method does not matter.
-    #   These routes map to a URL like /messages/rss, with a route of +rss_messages_url+.
-    # * <tt>:member</tt> - Same as <tt>:collection</tt>, but for actions that operate on a specific member.
-    # * <tt>:new</tt> - Same as <tt>:collection</tt>, but for actions that operate on the new \resource action.
-    # * <tt>:controller</tt> - Specify the controller name for the routes.
-    # * <tt>:singular</tt> - Specify the singular name used in the member routes.
-    # * <tt>:requirements</tt> - Set custom routing parameter requirements; this is a hash of either 
-    #     regular expressions (which must match for the route to match) or extra parameters. For example:
-    #
-    #       map.resource :profile, :path_prefix => ':name', :requirements => { :name => /[a-zA-Z]+/, :extra => 'value' }
-    #
-    #     will only match if the first part is alphabetic, and will pass the parameter :extra to the controller.
-    # * <tt>:conditions</tt> - Specify custom routing recognition conditions.  \Resources sets the <tt>:method</tt> value for the method-specific routes.
-    # * <tt>:as</tt> - Specify a different \resource name to use in the URL path. For example:
-    #     # products_path == '/productos'
-    #     map.resources :products, :as => 'productos' do |product|
-    #       # product_reviews_path(product) == '/productos/1234/comentarios'
-    #       product.resources :product_reviews, :as => 'comentarios'
-    #     end
-    #
-    # * <tt>:has_one</tt> - Specify nested \resources, this is a shorthand for mapping singleton \resources beneath the current.
-    # * <tt>:has_many</tt> - Same has <tt>:has_one</tt>, but for plural \resources.
-    #
-    #   You may directly specify the routing association with +has_one+ and +has_many+ like:
-    #
-    #     map.resources :notes, :has_one => :author, :has_many => [:comments, :attachments]
-    #
-    #   This is the same as:
-    #
-    #     map.resources :notes do |notes|
-    #       notes.resource  :author
-    #       notes.resources :comments
-    #       notes.resources :attachments
-    #     end
-    #
-    # * <tt>:path_names</tt> - Specify different path names for the actions. For example:
-    #     # new_products_path == '/productos/nuevo'
-    #     # bids_product_path(1) == '/productos/1/licitacoes'
-    #     map.resources :products, :as => 'productos', :member => { :bids => :get }, :path_names => { :new => 'nuevo', :bids => 'licitacoes' }
-    #
-    #   You can also set default action names from an environment, like this:
-    #     config.action_controller.resources_path_names = { :new => 'nuevo', :edit => 'editar' }
-    #
-    # * <tt>:path_prefix</tt> - Set a prefix to the routes with required route variables.
-    #
-    #   Weblog comments usually belong to a post, so you might use +resources+ like:
-    #
-    #     map.resources :articles
-    #     map.resources :comments, :path_prefix => '/articles/:article_id'
-    #
-    #   You can nest +resources+ calls to set this automatically:
-    #
-    #     map.resources :articles do |article|
-    #       article.resources :comments
-    #     end
-    #
-    #   The comment \resources work the same, but must now include a value for <tt>:article_id</tt>.
-    #
-    #     article_comments_url(@article)
-    #     article_comment_url(@article, @comment)
-    #
-    #     article_comments_url(:article_id => @article)
-    #     article_comment_url(:article_id => @article, :id => @comment)
-    #
-    #   If you don't want to load all objects from the database you might want to use the <tt>article_id</tt> directly:
-    #
-    #     articles_comments_url(@comment.article_id, @comment)
-    #
-    # * <tt>:name_prefix</tt> - Define a prefix for all generated routes, usually ending in an underscore.
-    #   Use this if you have named routes that may clash.
-    #
-    #     map.resources :tags, :path_prefix => '/books/:book_id', :name_prefix => 'book_'
-    #     map.resources :tags, :path_prefix => '/toys/:toy_id',   :name_prefix => 'toy_'
-    #
-    # You may also use <tt>:name_prefix</tt> to override the generic named routes in a nested \resource:
-    #
-    #   map.resources :articles do |article|
-    #     article.resources :comments, :name_prefix => nil
-    #   end
-    #
-    # This will yield named \resources like so:
-    #
-    #   comments_url(@article)
-    #   comment_url(@article, @comment)
-    #
-    # * <tt>:shallow</tt> - If true, paths for nested resources which reference a specific member
-    #   (ie. those with an :id parameter) will not use the parent path prefix or name prefix.
-    #
-    # The <tt>:shallow</tt> option is inherited by any nested resource(s).
-    #
-    # For example, 'users', 'posts' and 'comments' all use shallow paths with the following nested resources:
-    #
-    #   map.resources :users, :shallow => true do |user|
-    #     user.resources :posts do |post|
-    #       post.resources :comments
-    #     end
-    #   end
-    #   # --> GET /users/1/posts (maps to the PostsController#index action as usual)
-    #   #     also adds the usual named route called "user_posts"
-    #   # --> GET /posts/2 (maps to the PostsController#show action as if it were not nested)
-    #   #     also adds the named route called "post"
-    #   # --> GET /posts/2/comments (maps to the CommentsController#index action)
-    #   #     also adds the named route called "post_comments"
-    #   # --> GET /comments/2 (maps to the CommentsController#show action as if it were not nested)
-    #   #     also adds the named route called "comment"
-    #
-    # You may also use <tt>:shallow</tt> in combination with the +has_one+ and +has_many+ shorthand notations like:
-    #
-    #   map.resources :users, :has_many => { :posts => :comments }, :shallow => true
-    #
-    # * <tt>:only</tt> and <tt>:except</tt> - Specify which of the seven default actions should be routed to.
-    #
-    # <tt>:only</tt> and <tt>:except</tt> may be set to <tt>:all</tt>, <tt>:none</tt>, an action name or a
-    # list of action names. By default, routes are generated for all seven actions.
-    #
-    # For example:
-    #
-    #   map.resources :posts, :only => [:index, :show] do |post|
-    #     post.resources :comments, :except => [:update, :destroy]
-    #   end
-    #   # --> GET /posts (maps to the PostsController#index action)
-    #   # --> POST /posts (fails)
-    #   # --> GET /posts/1 (maps to the PostsController#show action)
-    #   # --> DELETE /posts/1 (fails)
-    #   # --> POST /posts/1/comments (maps to the CommentsController#create action)
-    #   # --> PUT /posts/1/comments/1 (fails)
-    #
-    # If <tt>map.resources</tt> is called with multiple resources, they all get the same options applied.
-    #
-    # Examples:
-    #
-    #   map.resources :messages, :path_prefix => "/thread/:thread_id"
-    #   # --> GET /thread/7/messages/1
-    #
-    #   map.resources :messages, :collection => { :rss => :get }
-    #   # --> GET /messages/rss (maps to the #rss action)
-    #   #     also adds a named route called "rss_messages"
-    #
-    #   map.resources :messages, :member => { :mark => :post }
-    #   # --> POST /messages/1/mark (maps to the #mark action)
-    #   #     also adds a named route called "mark_message"
-    #
-    #   map.resources :messages, :new => { :preview => :post }
-    #   # --> POST /messages/new/preview (maps to the #preview action)
-    #   #     also adds a named route called "preview_new_message"
-    #
-    #   map.resources :messages, :new => { :new => :any, :preview => :post }
-    #   # --> POST /messages/new/preview (maps to the #preview action)
-    #   #     also adds a named route called "preview_new_message"
-    #   # --> /messages/new can be invoked via any request method
-    #
-    #   map.resources :messages, :controller => "categories",
-    #         :path_prefix => "/category/:category_id",
-    #         :name_prefix => "category_"
-    #   # --> GET /categories/7/messages/1
-    #   #     has named route "category_message"
-    #
-    # The +resources+ method sets HTTP method restrictions on the routes it generates. For example, making an
-    # HTTP POST on <tt>new_message_url</tt> will raise a RoutingError exception. The default route in
-    # <tt>config/routes.rb</tt> overrides this and allows invalid HTTP methods for \resource routes.
-    def resources(*entities, &block)
-      options = entities.extract_options!
-      entities.each { |entity| map_resource(entity, options.dup, &block) }
-    end
-
-    # Creates named routes for implementing verb-oriented controllers for a singleton \resource.
-    # A singleton \resource is global to its current context.  For unnested singleton \resources,
-    # the \resource is global to the current user visiting the application, such as a user's
-    # <tt>/account</tt> profile.  For nested singleton \resources, the \resource is global to its parent
-    # \resource, such as a <tt>projects</tt> \resource that <tt>has_one :project_manager</tt>.
-    # The <tt>project_manager</tt> should be mapped as a singleton \resource under <tt>projects</tt>:
-    #
-    #   map.resources :projects do |project|
-    #     project.resource :project_manager
-    #   end
-    #
-    # See +resources+ for general conventions.  These are the main differences:
-    # * A singular name is given to <tt>map.resource</tt>.  The default controller name is still taken from the plural name.
-    # * To specify a custom plural name, use the <tt>:plural</tt> option.  There is no <tt>:singular</tt> option.
-    # * No default index route is created for the singleton \resource controller.
-    # * When nesting singleton \resources, only the singular name is used as the path prefix (example: 'account/messages/1')
-    #
-    # For example:
-    #
-    #   map.resource :account
-    #
-    # maps these actions in the Accounts controller:
-    #
-    #   class AccountsController < ActionController::Base
-    #     # GET new_account_url
-    #     def new
-    #       # return an HTML form for describing the new account
-    #     end
-    #
-    #     # POST account_url
-    #     def create
-    #       # create an account
-    #     end
-    #
-    #     # GET account_url
-    #     def show
-    #       # find and return the account
-    #     end
-    #
-    #     # GET edit_account_url
-    #     def edit
-    #       # return an HTML form for editing the account
-    #     end
-    #
-    #     # PUT account_url
-    #     def update
-    #       # find and update the account
-    #     end
-    #
-    #     # DELETE account_url
