<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
<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>Finally, the &apt-preferences; mechanism allows you to
create an alternative installation policy for
individual packages.</para>
