+Account Location
+================
+
+Account location is a set of protected methods that supports the account-key-as-subdomain 
+way of identifying the current scope. These methods allow you to easily produce URLs that
+match this style and to get the current account key from the subdomain.
+
+The methods are: `account_url`, `account_host`, and `account_domain`.
+
+current_account can be used to get and set the currently active account.
+
+
+Example:
+
+    class ApplicationController < ActionController::Base
+      include AccountLocation
+      before_filter :find_account
+
+      protected
+        def find_account
+          self.current_account = Account.find_by_username(account_subdomain)
+        end
+    end
+
+    class UsersController < ApplicationController
+      def index
+        @users = current_account.users.all
+      end
+    end
+
+    class AccountController < ApplicationController
+      def new
+        @new_account = Account.create(params[:new_account])
+        redirect_to :host => account_host(@new_account.username), :controller => "weblog"
+      end
+
+      def authenticate
+        session[account_domain] = :authenticated
+        redirect_to :controller => "weblog"
+      end
+
+      protected
+        def authenticated?
+          session[account_domain] == :authenticated
+        end
+    end
+
+And in your view:
+
+    Your domain: <%= account_url %>
+
+By default, all the methods will query for current_account.username as the account key, but you can
+specialize that by overwriting default_account_subdomain. You can of course also pass it in
+as the first argument to all the methods.
