<p>Here are the commands for formatting descriptions about abstract
objects, such as are used in object-oriented programming. A class is
a defined type of abstract object. An instance of a class is a
particular object that has the type of the class. An instance
variable is a variable that belongs to the class but for which each
instance has its own value.
