<span class="command"><strong>aptitude</strong></span> 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.<a href="#ftn.idm779" class="footnote" id="idm779"><sup class="footnote">[7]</sup></a>
</p><p>
In an attempt to combat this obscurity, this reference guide
describes every feature and configuration parameter of
<span class="command"><strong>aptitude</strong></span>. For a more gentle guide to the important features
of <span class="command"><strong>aptitude</strong></span>, see <a class="xref" href="ch01.html" title="Chapter 1. Getting started">Chapter 1, <em>Getting started</em></a>.

<span class="command"><strong>aptitude</strong></span>'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
