class Class
# Declare a class-level attribute whose value is inheritable by subclasses.
# Subclasses can change their own value and it will not impact parent class.
#
+ # ==== Options
+ #
+ # * <tt>:instance_reader</tt> - Sets the instance reader method (defaults to true).
+ # * <tt>:instance_writer</tt> - Sets the instance writer method (defaults to true).
+ # * <tt>:instance_accessor</tt> - Sets both instance methods (defaults to true).
+ # * <tt>:instance_predicate</tt> - Sets a predicate method (defaults to true).
+ # * <tt>:default</tt> - Sets a default value for the attribute (defaults to nil).
+ #
+ # ==== Examples
+ #
# class Base
# class_attribute :setting
