The oslo.i18n library contain utilities for working with internationalization (i18n) features, especially translation for text strings in an application or library.

The cliff framework allows creating multi-level commands such as those of subversion and git, where the main program handles some basic argument parsing and then invokes a sub-command to do the work. It uses plugins to define sub-commands, output formatters, and other extensions.

The oslo.utils library provides support for common utility type functions, such as encoding, exception handling, string manipulation, and time handling.

Keystoneauth provides a standard way to do authentication and service requests within the OpenStack ecosystem. It is designed for use in conjunction with the existing OpenStack clients and for simplifying the process of writing new clients.

This package provides a client library for building applications to work with OpenStack clouds. The SDK aims to provide a consistent and complete set of interactions with OpenStack’s many services, along with complete documentation, examples, and tools.

This package provides an utility that accesses files on a HTTP server and stores them locally for reuse. It is primarily used by the Orange framework.

Orange Widget Base provides a base widget component for a interactive GUI based workflow. It is primarily used in the Orange framework.

Orange is a component-based, graphical framework for machine learning, data analysis, data mining and data visualization.

Orange Canvas Core is a framework for building graphical user interfaces for editing workflows. It is a component used to build the Orange Canvas data-mining application.

Orpheus is a light-weight text mode menu- and window-driven audio player application for CDs, internet stream broadcasts, and files in MP3 and Vorbis OGG format.

The Open Text Summarizer is a library and command-line tool for summarizing texts. The program reads a text and decides which sentences are important and which are not. OTS will create a short summary or will highlight the main ideas in the text.

The program can either print the summarized text as plain text or HTML. If in HTML, the important sentences are highlighted.

The program is multi lingual and works with UTF-8 encoding.

oyacc is a portable version of the OpenBSD's yacc program, with no dependencies besides libc.

Poetry is a tool for dependency management and packaging in Python. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

The Guix Build Coordinator helps with performing lots of builds across potentially many machines, and with doing something with the results and outputs of those builds.

This package just includes the agent component.

Akku.scm is a project-based language package manager for R6RS and R7RS Scheme. It is mainly meant for programmers who develop portable programs or libraries in Scheme, but could potentially work for end-users of those programs. It also has a translator from R7RS, which allows most R7RS code to run on R6RS implementations.

Nix is a purely functional package manager. This means that it treats packages like values in purely functional programming languages such as Haskell—they are built by functions that don't have side-effects, and they never change after they have been built. Nix stores packages in the Nix store, usually the directory /nix/store, where each package has its own unique sub-directory.

GNU Guix is a functional package manager for the GNU system, and is also a distribution thereof. It includes a virtual machine image. Besides the usual package management features, it also supports transactional upgrades and roll-backs, per-user profiles, and much more. It is based on the Nix package manager.

GNU Stow is a symlink manager. It generates symlinks to directories of data and makes them appear to be merged into the same directory. It is typically used for managing software packages installed from source, by letting you install them apart in distinct directories and then create symlinks to the files in a common directory such as /usr/local.

The Guix Build Coordinator helps with performing lots of builds across potentially many machines, and with doing something with the results and outputs of those builds.

XStow is a replacement of GNU Stow written in C++. It supports all features of Stow with some extensions.

The SVG files in this directory are intended to be used as backgrounds for different components of the GNU system like login managers and desktop environments. The backgrounds are available in different aspect ratios which are indicated in the file name.

The RPM Package Manager (RPM) is a command-line driven package management system capable of installing, uninstalling, verifying, querying, and updating computer software packages. Each software package consists of an archive of files along with information about the package like its version, a description. There is also a library permitting developers to manage such transactions from C or Python.

libostree is both a shared library and suite of command line tools that combines a "git-like" model for committing and downloading bootable file system trees, along with a layer for deploying them and managing the boot loader configuration.

The Nar Herder is a utility for managing a collection of nars (normalized archives, in the context of Guix) along with the corresponding narinfo files which contain some signed metadata.

It can assist in serving a collection of nars, moving them between machines, or mirroring an existing collection of nars.

It's currently a working prototype, many designed features aren't implemented, and the error handling is very rough.
