Among all of the distributions of GNU/Linux can be said, without any doubt, that the management system of packages of Debian GNU/Linux is the most comprehensive in all, and that provides the tools more interesting to the administrator of such systems.
Two types of Debian packages exist:
Binary Packages, which contain executables, configuration files, man pages/info, information on copyright and other documentation. These packages are distributed in a file format Debian-specific distinguished by having a .deb file extension. The binary packages can be unpacked using the usefulness of Debian dpkg.
Packages sources, that consist of file .dsc that describes the package (including the name of the archives that follows), a .orig.tar.gz file that contains the original source code without modifying in format to tar tablet with gzip and, generally, a .diff.gz file that contains the changes of the specific original source code of Debian. The utility dpkg-source packs and unpacks the source files of Debian.
he tools of the packages of Debian can be used for:
* to manipulate and to administer to packages or parts of packages.
* to help the user to divide packages that must be distributed through means of size limited like, for example, disketes.
* to attend the developers in the construction of packages and to help the users to install packages that are in remote Debian sites
