“Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice.”
Christopher Alexander

•the commands attached to menu items
•file allocation tables is the directory system
•But it does address the core of the solution to an important piece of each problem
