+ <para><command>apt-mark</command> can be used as a unified front-end to set
+ various settings for a package, such as marking a package as being
+ automatically/manually installed or changing <command>dpkg</command>
+ selections such as hold, install, deinstall and purge which are respected
+ e.g. by <command>apt-get dselect-upgrade</command> or <command>aptitude</command>.

+ </refsect1><refsect1><title>Automatically and Manually Installed Packages</title>
+ <para>
+ When you request that a package is installed, and as a result
+ other packages are installed to satisfy its dependencies, the
+ dependencies are marked as being automatically installed, while the
+ package you installed explicitly is marked as manually installed.
+ Once an automatically installed package is no longer depended on
+ by any manually installed package it is considered no longer needed
+ and e.g. <command>apt-get</command> or <command>aptitude</command>
+ will at least suggest removing them.

+ <para>
+ Some front-ends like <command>apt-get dselect-upgrade</command> can be used to
+ apply previously scheduled changes to the install state of packages. Such changes
+ can be scheduled with the <option>install</option>, <option>remove</option>
+ (also known as <option>deinstall</option>) and <option>purge</option> commands.
+ Packages with a specific selection can be displayed with <option>showinstall</option>,
+ <option>showremove</option> and <option>showpurge</option> respectively.
+ More information about these so called dpkg selections can be found in &dpkg;.
