+ <refsect1><title>Description</title>
+   <para><command>apt-get</command> is the command-line tool for handling packages, and may be 
+   considered the user's "back-end" to other tools using the APT
+   library.  Several "front-end" interfaces exist, such as
+   &aptitude;, &synaptic; and &wajig;.</para>
+
+   <para>Unless the <option>-h</option>, or <option>--help</option> option is given, one of the
+   commands below must be present.</para>
+   
+   <variablelist>
+     <varlistentry><term><option>update</option></term>
+     <listitem><para><literal>update</literal> is used to resynchronize the package index files from
+     their sources. The indexes of available packages are fetched from the
+     location(s) specified in <filename>/etc/apt/sources.list</filename>.
+     For example, when using a Debian archive, this command retrieves and
+     scans the <filename>Packages.gz</filename> files, so that information about new 
+     and updated packages is available. An <literal>update</literal> should always be 
+     performed before an <literal>upgrade</literal> or <literal>dist-upgrade</literal>. Please 
+     be aware that the overall progress meter will be incorrect as the size 
+     of the package files cannot be known in advance.</para></listitem>
+     </varlistentry>
+     
+     <varlistentry><term><option>upgrade</option></term>
+     <listitem><para><literal>upgrade</literal> is used to install the newest versions of all packages 
+     currently installed on the system from the sources enumerated in
+     <filename>/etc/apt/sources.list</filename>. Packages currently installed with 
+     new versions available are retrieved and upgraded; under no circumstances 
+     are currently installed packages removed, or packages not already installed 
+     retrieved and installed. New versions of currently installed packages that 
+     cannot be upgraded without changing the install status of another package 
+     will be left at their current version. An <literal>update</literal> must be 
+     performed first so that <command>apt-get</command> knows that new versions of packages are 
+     available.</para></listitem>
+     </varlistentry>
+
+     <varlistentry><term><option>dist-upgrade</option></term>
+     <listitem><para><literal>dist-upgrade</literal> in addition to performing the function of 
+     <literal>upgrade</literal>, also intelligently handles changing dependencies 
+     with new versions of packages; <command>apt-get</command> has a "smart" conflict 
+     resolution system, and it will attempt to upgrade the most important 
+     packages at the expense of less important ones if necessary. 
+     The <literal>dist-upgrade</literal> command may therefore remove some packages.
+     The <filename>/etc/apt/sources.list</filename> file contains a list of locations 
+     from which to retrieve desired package files.
+     See also &apt-preferences; for a mechanism for
+     overriding the general settings for individual packages.</para></listitem>
+     </varlistentry>
+
+     <varlistentry><term><option>dselect-upgrade</option></term>
+     <listitem><para><literal>dselect-upgrade</literal>
+     is used in conjunction with the traditional Debian packaging
+     front-end, &dselect;. <literal>dselect-upgrade</literal>
+     follows the changes made by &dselect; to the <literal>Status</literal>
+     field of available packages, and performs the actions necessary to realize
+     that state (for instance, the removal of old and the installation of new
+     packages).</para></listitem>
+     </varlistentry>
+
+     <varlistentry><term><option>install</option></term>
+     <listitem>
+	 <para><literal>install</literal> is followed by one or more 
+	 packages desired for installation or upgrading. 
+	 Each package is a package name, not a fully qualified 
+	 filename (for instance, in a Debian system, 
+	 <package>apt-utils</package> would be the argument provided, not 
+	 <filename>apt-utils_&apt-product-version;_amd64.deb</filename>). All packages required 
+	 by the package(s) specified for installation will also 
+	 be retrieved and installed. 
+	 The <filename>/etc/apt/sources.list</filename> file is 
+	 used to locate the desired packages. If a hyphen is 
+	 appended to the package name (with no intervening space), 
+	 the identified package will be removed if it is installed. 
+	 Similarly a plus sign can be used to designate a 
+	 package to install. These latter features may be used 
+	 to override decisions made by apt-get's conflict 
+	 resolution system.
+	 </para>
+
+     <para>A specific version of a package can be selected for installation by 
+     following the package name with an equals and the version of the package 
+     to select. This will cause that version to be located and selected for
+     install. Alternatively a specific distribution can be selected by 
+     following the package name with a slash and the version of the 
+     distribution or the Archive name (stable, testing, unstable).</para>
+
+     <para>Both of the version selection mechanisms can downgrade packages and must
+     be used with care.</para>
+
+	<para>This is also the target to use if you want to upgrade one or 
+		more already-installed packages without upgrading every package 
+		you have on your system. Unlike the "upgrade" target, which 
+		installs the newest version of all currently installed packages, 
+		"install" will install the newest version of only the package(s) 
+		specified. Simply provide the name of the package(s) you wish 
+		to upgrade, and if a newer version is available, it (and its 
+		dependencies, as described above) will be downloaded and 
+		installed.
+	</para>
+
+     <para>Finally, the &apt-preferences; mechanism allows you to
+     create an alternative installation policy for
+     individual packages.</para>
+
+     <para>If no package matches the given expression and the expression contains one
+     of '.', '?' or '*' then it is assumed to be a POSIX regular expression,
+     and it is applied
+     to all package names in the database. Any matches are then installed (or
+     removed). Note that matching is done by substring so 'lo.*' matches 'how-lo'
+     and 'lowest'. If this is undesired, anchor the regular expression
+     with a '^' or '$' character, or create a more specific regular expression.</para>
+     <para>Fallback to regular expressions is deprecated in APT 2.0, has been removed in
+     &apt;, except for anchored expressions, and will be removed from &apt-get;
+     in a future version. Use &apt-patterns; instead.</para></listitem>

+     <listitem><para><literal>remove</literal> is identical to <literal>install</literal> except that packages are 
+	 removed instead of installed. Note that removing a package leaves its
+	 configuration files on the system. If a plus sign is appended to the package 
+     name (with no intervening space), the identified package will be 
+     installed instead of removed.</para></listitem>

+
+     <varlistentry><term><option>source</option></term>
+     <listitem><para><literal>source</literal> causes <command>apt-get</command> to fetch source packages. APT 
+     will examine the available packages to decide which source package to 
+     fetch. It will then find and download into the current directory the 
+     newest available version of that source package while respecting the
+     default release, set with the option <literal>APT::Default-Release</literal>,
+     the <option>-t</option> option or per package with the
+     <literal>pkg/release</literal> syntax, if possible.</para>
+
+    <para>The arguments are interpreted as binary and source package names.
+    See the <option>--only-source</option> option if you want to change that.</para>
+
+     <para>Source packages are tracked separately
+     from binary packages via <literal>deb-src</literal> lines 
+     in the &sources-list; file. This means that you will need to add such a line
+     for each repository you want to get sources from; otherwise you will probably
+     get either the wrong (too old/too new) source versions or none at all.</para>
+
+     <para>If the <option>--compile</option> option is specified
+     then the package will be compiled to a binary .deb using
+     <command>dpkg-buildpackage</command> for the architecture as
+     defined by the <command>--host-architecture</command> option.
+     If <option>--download-only</option> is specified then the source package
+     will not be unpacked.</para>
+
+     <para>A specific source version can be retrieved by postfixing the source name
+     with an equals and then the version to fetch, similar to the mechanism
+     used for the package files. This enables exact matching of the source 
+     package name and version, implicitly enabling the 
+     <literal>APT::Get::Only-Source</literal> option.</para>
+
+     <para>Note that source packages are not installed and tracked in the
+     <command>dpkg</command> database like binary packages; they are simply downloaded
+     to the current directory, like source tarballs.</para></listitem>
