dpkg-preconfigure - let packages ask questions prior to their installation

       Joey Hess <joeyh@debian.org>

dpkg-preconfigure lets packages ask questions before they are installed.  It operates on a set of debian
       packages, and all packages that use cdebconf will have their config script run so they can examine the
       system and ask questions.

       This manpage was "borrowed" from debconf.

-ftype, --frontend=type
           Select the frontend to use.

       -pvalue, --priority=value
           Set  the  lowest priority of questions you are interested in. Any questions with a priority below the
           selected priority will be ignored and their default answers will be used.

       --apt
           Run in apt mode. It will expect to read a set of package filenames from stdin,  rather  than  getting
           them  as  parameters. Typically this is used to make apt run dpkg-preconfigure on all packages before
           they are installed.  To do this, add something like this to /etc/apt/apt.conf:

            // Pre-configure all packages before
            // they are installed.
            DPkg::Pre-Install-Pkgs {
                   "dpkg-preconfigure --apt --priority=low";
            };

       -h, --help
           Display usage help.
