Package format

A package format is a type of archive containing computer programs and additional metadata needed by package managers.^[1] While the archive file format itself may be unchanged, package formats bear additional metadata, such as a manifest file or certain directory layouts. Packages may contain either source code or executable files.

Packages may be converted to one type to another with software such as Alien.
