     SYNOPSIS
          apt-mark {-f=filename | {auto | manual} pkg...  |
                   {showauto | showmanual} [pkg...] } |

                   {showhold | showinstall | showremove | showpurge} [pkg...]

     DESCRIPTION
          apt-mark can be used as a unified front-end to set various
          settings for a package, such as marking a package as being
          automatically/manually installed or changing dpkg selections
          such as hold, install, deinstall and purge which are
          respected e.g. by apt-get dselect-upgrade or aptitude.

     AUTOMATICALLY AND MANUALLY INSTALLED PACKAGES
          When you request that a package is installed, and as a
          result other packages are installed to satisfy its
          dependencies, the dependencies are marked as being
          automatically installed, while the package you installed
          explicitly is marked as manually installed. Once an
          automatically installed package is no longer depended on by
          any manually installed package it is considered no longer
          needed and e.g.  apt-get or aptitude will at least suggest
          removing them.

          auto
              auto is used to mark a package as being automatically
              installed, which will cause the package to be removed
              when no more manually installed packages depend on this
              package.

          manual
              manual is used to mark a package as being manually
              installed, which will prevent the package from being
              automatically removed if no other packages depend on it.

          minimize-manual
              minimize-manual is used to mark (transitive)
              dependencies of metapackages as automatically installed.
              This can be used after an installation for example, to
              minimize the number of manually installed packages; or
              continuously on systems managed by system configuration
              metapackages.

          showauto
              showauto is used to print a list of automatically
              installed packages with each package on a new line. All
              automatically installed packages will be listed if no
              package is given. If packages are given only those which
              are automatically installed will be shown.

          showmanual
              showmanual can be used in the same way as showauto
              except that it will print a list of manually installed
              packages instead.

        Options
          -f=filename, --file=filename
              Read/Write package stats from the filename given with
              the parameter filename instead of from the default
              location, which is extended_states in the directory
              defined by the Configuration Item: Dir::State.

     PREVENT CHANGES FOR A PACKAGE
          hold
              hold is used to mark a package as held back, which will
              prevent the package from being automatically installed,
              upgraded or removed.

          unhold
              unhold is used to cancel a previously set hold on a
              package to allow all actions again.

          showhold
              showhold is used to print a list of packages on hold in
              the same way as for the other show commands.

     SCHEDULE PACKAGES FOR INSTALL, REMOVE AND PURGE
          Some front-ends like apt-get dselect-upgrade can be used to
          apply previously scheduled changes to the install state of
          packages. Such changes can be scheduled with the install,
          remove (also known as deinstall) and purge commands.
          Packages with a specific selection can be displayed with
          showinstall, showremove and showpurge respectively. More
          information about these so called dpkg selections can be
          found in dpkg(1).

     OPTIONS
          -h, --help
              Show a short usage summary.

          -v, --version
              Show the program version.

          -c, --config-file
              Configuration File; Specify a configuration file to use.

              The program will read the default configuration file and
              then this configuration file. If configuration settings
              need to be set before the default configuration files
              are parsed specify a file with the APT_CONFIG
              environment variable. See apt.conf(5) for syntax
              information.

          -o, --option
              Set a Configuration Option; This will set an arbitrary
              configuration option. The syntax is -o Foo::Bar=bar.  -o
              and --option can be used multiple times to set different
              options.

     FILES
          /var/lib/apt/extended_states
              Status list of auto-installed packages. Configuration
              Item: Dir::State::extended_states.

     DIAGNOSTICS
          apt-mark returns zero on normal operation, non-zero on
