<refsect1><title>Description</title>
- <para><command>apt-mark</command> will change whether a package has
- been marked as being automatically installed.
+ <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>.
</para>
+ </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. Once
- these automatically installed packages are no longer depended on
- by any manually installed packages, they will be removed by e.g.
- <command>apt-get</command> or <command>aptitude</command>.
+ 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.
