38 <refsect1><title>Description</title>
39 <para><command>apt-mark</command> will change whether a package has
40 been marked as being automatically installed.
41 </para>
42 <para>
43 When you request that a package is installed, and as a result
44 other packages are installed to satisfy its dependencies, the
45 dependencies are marked as being automatically installed. Once
46 these automatically installed packages are no longer depended on
47 by any manually installed packages, they will be removed by e.g.
48 <command>apt-get</command> or <command>aptitude</command>.
49 </para>
50 <variablelist>
51 <varlistentry><term><option>auto</option></term>
52 <listitem><para><literal>auto</literal> is used to mark a
53 package as being automatically installed, which will cause the
54 package to be removed when no more manually installed packages
55 depend on this package.
56 </para></listitem>

58
59 <varlistentry><term><option>manual</option></term>
60 <listitem><para><literal>manual</literal> is used to mark a
61 package as being manually installed, which will prevent the
62 package from being automatically removed if no other packages
63 depend on it.
64 </para></listitem>
65 </varlistentry>
66
67 <varlistentry><term><option>hold</option></term>
68 <listitem><para><literal>hold</literal> is used to mark a
69 package as held back, which will prevent the package from being
70 automatically installed, upgraded or removed.
71 The command is only a wrapper around <command>dpkg --set-selections</command>
72 and the state is therefore maintained by &dpkg; and not affected
73 by the <option>--file</option> option.

77 <varlistentry><term><option>unhold</option></term>
78 <listitem><para><literal>unhold</literal> is used to cancel a
79 previously set hold on a package to allow all actions again.

82
83 <varlistentry><term><option>showauto</option></term>
84 <listitem><para><literal>showauto</literal> is used to print a
85 list of automatically installed packages with each package on a new line.
86 All automatically installed packages will be listed if no package is given.
87 If packages are given only those which are automatically installed will be shown.

94 a list of manually installed packages instead.

98 <varlistentry><term><option>showhold</option></term>
