This package written by Sander van der Burg contains a function for the Nix package manager that automatically builds AmigaOS software packages using Geek Gadgets, a GNU build tool chain ported to AmigaOS, and an Amiga emulator (either the “vanilla” UAE or FS-UAE). With this Nix function, one can easily build software for AmigaOS (e.g. for porting) the same way as ordinary packages are built by using the Nix package manager for modern platforms such as Linux. Furthermore, this package includes several example cases demonstrating its use. Nix is a powerful package manager for Linux and other Unix systems that makes package management reliable and reproducible. It provides atomic upgrades and rollbacks, side-by-side installation of multiple versions of a package, multi-user package management and easy setup of build environments.
