aptitude is a large program with many features, and it is sometimes difficult to remember how to do something, or even to remember whether that something is even possible. Indeed, many feature requests received by the author describe features which are already present but are difficult to find.^[7]

In an attempt to combat this obscurity, this reference guide describes every feature and configuration parameter of aptitude. For a more gentle guide to the important features of aptitude, see Kapitel 1, Komma igång.

	aptitude's behavior and appearance can be configured in a number of ways. This manual describes how the program works with the default settings; descriptions of how various settings affect behavior are given in “Anpassa aptitude”.
