Cargo
Cargo is the Rust package manager. Cargo downloads your Rust package's dependencies, compiles your packages, makes distributable packages, and uploads them to crates.io, the Rust community’s package registry. You can contribute to this book on GitHub. To get started with Cargo, install Cargo (and Rust) and set up your first crate. The commands will let you interact with Cargo using its command-line interface. A Rust crate is either a library or an executable program, referred to as either a library crate or a binary crate, respectively. Loosely, the term crate may refer to either the source code of the target or to the compiled artifact that the target produces. It may also refer to a compressed package fetched from a registry. Your crates can depend on other libraries from crates.io or other registries, git repositories, or subdirectories on your local file system. You can also temporarily override the location of a dependency.

MSYS2
MSYS2 is a collection of tools and libraries providing you with an easy-to-use environment for building, installing and running native Windows software. It consists of a command line terminal called mintty, bash, version control systems like git and subversion, tools like tar and awk and even build systems like autotools, all based on a modified version of Cygwin. Despite some of these central parts being based on Cygwin, the main focus of MSYS2 is to provide a build environment for native Windows software and the Cygwin-using parts are kept at a minimum. MSYS2 provides up-to-date native builds for GCC, mingw-w64, CPython, CMake, Meson, OpenSSL, FFmpeg, Rust, Ruby, just to name a few. To provide easy installation of packages and a way to keep them updated it features a package management system called Pacman, which should be familiar to Arch Linux users.

Fink
The Fink project wants to bring the full world of Unix open source software to Darwin and Mac OS X. We modify Unix software so that it compiles and runs on Mac OS X ("port" it) and make it available for download as a coherent distribution. Fink uses Debian tools like dpkg and apt-get to provide powerful binary package management. You can choose whether you want to download precompiled binary packages or build everything from source. The project offers precompiled binary packages as well as a fully automated build-from-source system. Mac OS X includes only a basic set of command-line tools. Fink brings you enhancements for these tools as well as a selection of graphical applications developed for Linux and other Unix variants. With Fink the compile process is fully automated; you'll never have to worry about Makefiles or configure scripts and their parameters again. The dependency system automatically takes care that all required libraries are present.
