+module ActionController #:nodoc:
+  # Cookies are read and written through ActionController#cookies. The cookies being read is what was received along with the request,
+  # the cookies being written is what will be sent out will the response. Cookies are read by value (so you won't get the cookie object
+  # itself back -- just the value it holds). Examples for writting:
+  #
+  #   cookies["user_name"] = "david" # => Will set a simple session cookie
+  #   cookies["login"] = { "value" => "XJ-122", "expires" => Time.now + 360} # => Will set a cookie that expires in 1 hour
+  #   
+  # Examples for reading:
+  #
+  #   cookies["user_name"] # => "david"
+  #   cookies.size         # => 2
+  #
+  # All the options for setting cookies are:
+  #
+  # value:: the cookie's value or list of values (as an array).
+  # path:: the path for which this cookie applies.  Defaults to the root of the application.
+  # domain:: the domain for which this cookie applies.
+  # expires:: the time at which this cookie expires, as a +Time+ object.
+  # secure:: whether this cookie is a secure cookie or not (default to false).
+  #          Secure cookies are only transmitted to HTTPS servers.
+  module Cookies
+    # Returns the cookie container, which operates as described above.
