Debian packages are also used in operating systems based on Debian.

Debian packages are standard Unix ar archives that include two gzipped or bzipped tar archives: one that holds the control information and another that contains the data.

The canonical program for handling these packages is dpkg, most commonly via apt/aptitude.

deb packages can be converted into other packages and vice versa using Alien.
