  53      newest versions of all packages currently installed on the system
  54      from the sources enumerated in
  55      <filename>/etc/apt/sources.list</filename>. New package will be
  56      installed, but existing package will never removed.

  66      <para>A specific version of a package can be selected for installation by
  67      following the package name with an equals and the version of the package
  68      to select. This will cause that version to be located and selected for
  69      install. Alternatively a specific distribution can be selected by
  70      following the package name with a slash and the version of the
  71      distribution or the Archive name (stable, testing, unstable).</para>

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

  97  <para>The <command>apt</command> command is meant to be pleasant for
  98  end users and does not need to be backward compatilbe like
  99  &apt-get;. Therefore some options are different:
 100
 101  <itemizedlist>
 102    <listitem>The option <literal>DPkgPM::Progress-Fancy</literal> is enabled.
 103    </listitem>
 104    <listitem>The option <literal>APT::Color</literal> is enabled.
 105    </listitem>
 106    <listitem>A new <literal>list</literal> command is available
 107    similar to <literal>dpkg --list</literal>.
 108    </listitem>
 109    <listitem>The option <literal>upgrade</literal> has
 110    <literal>--with-new-pkgs</literal> enabled by default.
 111    </listitem>
