<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

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.

from which to retrieve desired package files.

- <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 GNU/Linux system,
- libc6 would be the argument provided, not
- <literal>libc6_1.9.6-2.deb</literal>). 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
