Cargo
Cargo serves as the package manager for Rust, handling tasks such as downloading dependencies, compiling packages, creating distributable versions, and uploading them to crates.io, which is the Rust community's designated package registry. Contributions to this book can be made through GitHub. To begin using Cargo, you need to install both Cargo and Rust, then create your first crate. Through the command-line interface, you will be able to interact with Cargo easily. A Rust crate can be classified as either a library or an executable, known respectively as a library crate or a binary crate. Generally speaking, the term crate can denote the source code of the project or the compiled output it generates. Additionally, it may also refer to a compressed package obtained from a registry. You can create crates that depend on external libraries available on crates.io, other registries, git repositories, or even local subdirectories. Moreover, there is an option to temporarily change the location of a dependency, providing flexibility in your project management. This versatility makes Cargo an essential tool for Rust developers.

Synaptic
Synaptic is a user-friendly graphical interface for managing packages through the apt system, offering functionalities similar to the apt-get command-line tool but with a more accessible Gtk+ front-end. Users can easily install, uninstall, upgrade, or downgrade both individual and multiple software packages, as well as perform comprehensive system upgrades. The program allows for the management of package repositories through the sources.list file and facilitates searching for packages based on various criteria, including name and description. Additionally, it provides the capability to filter and select packages by their status, section, or customized parameters, while sorting can be done according to name, status, size, or version. Users can explore available online documentation for specific packages and access the latest changelog versions. The tool also includes functionalities to lock packages to their current versions, enforce the installation of particular package versions, and utilize undo/redo features for selection changes. Furthermore, a built-in terminal emulator enhances the package management experience, and for users on Debian/Ubuntu systems, it allows configuration through the debconf system and supports fast searching via Xapian, thanks to contributions from Enrico Zini. Overall, Synaptic is an essential tool for users who prefer a graphical approach to package management while still retaining the powerful capabilities of apt.
