== Package Management Tools

The are several tools available on a Debian system for the management of packages and the ["PkgDB"] package database.

=== _Tools for everyday use_

| ["dselect"] | The default ["ncurses"] based package manager. | ["synaptic"] | This is an ["X11"] based package mananger.

=== _Tools for advanced use_

| ["apt"] | Advanced package tool | ["apt-key"] | This tool is used for managing package authentication keys | ["dpkg"] | This is the main utility program that handles installation and removal of packages. All other tools are frontends for dpkg, and many users rarely use this tool directly. | ["apt-get"] | Used to organize the installation of packages (dpkg does the actual installing, apt-get handles dependencies, etc). | ["apt-cache"] | Used to search the contents of the entire package database in the ["sources"] list (as opposed to dpkg searches, which only search the contents of installed packages). | ["dpkg-deb"] | This tool is used to pack, unpack and provides information about package files. | ["dpkg-divert"] | A tool for installing a package in a non-default location | ["dpkg-query"] | A tool for querying the package database | ["dpkg-statoverride"] | A tool for overriding modes and ownerships of files | ["apt-file"] | This tool searches for a filename installed by any package in the contents of sources.list. | ["apt-listchanges"] | This tool displays the relevant changelog entries whenever a package is upgraded. | ["apt-build"] | Used to build packages from the source filesof this and haven't tried it myself. :) | ["apt-cdrom"] | This tool allows ["cdrom"] based sources to be included in the package sources list. | ["apt-rdepends"] | This tool generates recursive dependency trees for a package. | ["apt-spy"] | This tool is used to generate a sources.list file from the current list of mirrors, based on latency/bandwidth. | ["apt-show-versions"] | shows all available versions of a package (allows wildcards), or all packages, and displays upgrade information where applicable. | ["dpkg-reconfigure"] | Allows a package to be reconfigured based on preferences (the same questions that are asked when the package is first installed). | ["apt-show-source"] | This is a variant of "apt-cache show" that shows information against the named source package, rather than the binary package. | ["apt-listbugs"] | This tool shows known critical bugs in named packages. | ["apt-zip"] | This tool allows non-networked machines to export a list of packages selected for install using removable media. | ["apt-config"] | This program is used by the other apt utilities to provide a standard interface to the apt configuration settings. | ["apt-sortpkgs"] | Sorts records and fields within the sources and packages files. | ["apt-extracttemplates"] | Extracts templates and install scripts from packages. | ["apt-setup"] | This tool configures the sources.list file. | ["auto-apt"] | This tool checks the file access of programs running within its environments, and automatically installs packages if a program tries to access a file known to belong in an uninstalled package. | ["deborphan"] | This tool scans the package database for unused or redundant packages | ["debuild"] | This tool is used for rebuilding packages

=== _Tools for managing a package repository_

| ["apt-cacher"] | This is an alternative tool to apt-proxy. | ["apt-proxy"] | This is a specialized proxy server for accessing apt repositories. This can be used on a network to get packages from a central server that only downloads from the mirrors once. | ["apt-proxy-import"] | Imports packages into a cache used by apt-proxy. | ["apt-ftparchive"] | generates, from a directory of packages, the ["Packages"] and ["Sources"] control files used for an apt repository. | ["apt-move"] | Moves a collection of Debian packages into a proper ["pool"] directory hierarchy as used by a package repository.

=== _Alternative tools_

| ["aptitude"] | An alternative package manager to ["dselect"], containing additional features. | ["gdpm"] | Gnome Debian Package Manager (in development). | ["gnome-apt"] | Gnome Advanced Package Tool (in development). | ["pdbv"] | A tool for creating an xhtml view of the package database.
