DESCRIPTION

       apt-mark will change whether a package has been marked as being
       automatically installed.

       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. Once these automatically
       installed packages are no longer depended on by any manually installed
       packages, they will be removed by e.g.  apt-get or aptitude.

       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.

       hold
           hold is used to mark a package as held back, which will prevent the
           package from being automatically installed, upgraded or removed.
           The command is only a wrapper around dpkg --set-selections and the
           state is therefore maintained by dpkg(1) and not affected by the
           --file option.

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

       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.

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