PARI/GP is a widely used computer algebra system designed for fast computations in number theory (factorisations, algebraic number theory, elliptic curves...), but it also contains a large number of other useful functions to compute with mathematical entities such as matrices, polynomials, power series, algebraic numbers, etc., and a lot of transcendental functions. PARI is also available as a C library to allow for faster computations.

GP2C, the GP to C compiler, translates GP scripts to PARI programs.

Givaro is a C++ library implementing the basic arithmetic of various algebraic objects: prime fields, extension fields, finite fields, finite rings, polynomials, algebraic numbers, arbitrary precision integers and rationals (C++ wrappers over gmp), fixed precision integers. It also provides data-structures and templated classes for the manipulation of compound objects, such as vectors, matrices and univariate polynomials.

libsemigroups is a C++14 library containing implementations of several algorithms for computing finite, and finitely presented, semigroups and monoids.

FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data---i.e. the discrete cosine/ sine transforms or DCT/DST). With OpenMPI parallelism support.

M4RI is a library for fast arithmetic with dense matrices over finite fields of characteristic 2. So it extends the functionality of M4RI from F_2 to F_2^e.

Mpfrcx is a library for the arithmetic of univariate polynomials over arbitrary precision real (mpfr) or complex (mpc) numbers, without control on the rounding. For the time being, only the few functions needed to implement the floating point approach to complex multiplication are implemented. On the other hand, these comprise asymptotically fast multiplication routines such as Toom–Cook and the FFT.

The eclib package includes mwrank (for 2-descent on elliptic curves over Q) and modular symbol code; it has been written by John Cremona to compute his elliptic curve database.

Singular is a computer algebra system for polynomial computations, with special emphasis on commutative and non-commutative algebra, algebraic geometry and singularity theory.

Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms. It provides an elegant API based on "expression templates". It is versatile: it supports all matrix sizes, all standard numeric types, various matrix decompositions and geometry features, and more.

This package provides Python bindings for the Littlewood-Richardson Calculator.

android-libutils provides utilities for Android NDK developers.

This package provides a Qt graphical interface for transferring files with Android devices using MTP. It also allows the Android device to be mounted via FUSE.

This package provides a tool for manipulating old Android Boot Images. abootimg can work directly on block devices, or, the safest way, on a file image.

This package provides fastboot, a tool to upload file system images to Android devices.

android-safe-iop provides a set of functions for performing and checking safe integer operations. Ensure that integer operations do not result in silent overflow.

An rsync-like command-line utility that facilitates file transfer over ADB. There are several additional features over Google's original adbsync version with support for the --exclude, --exclude-from, --del, and --delete-excluded command line flags, which have the same purpose to the corresponding rsync flags.

android-bionic-uapi provides the part of the Linux API that is safe to use for user space. It also includes system_properties.h and _system_properties.h.

Google Test features an XUnit test framework, automated test discovery, death tests, assertions, parameterized tests and XML test report generation.

This package provides a standalone port of AOSP's libsparse that converts Android sparse filesystem images into raw ext4 images, avoiding the need for the full Android build chain.

adb is a versatile command line tool that lets you communicate with an emulator instance or connected Android device. It facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that can run commands on the connected device or emulator.

This package provides a drop-in replacement for sdkmanager from the Android SDK. It is written in Python and part of the F-Droid project. It implements the exact API of the Android sdkmanager command line. The project also attempts to maintain the same terminal output.

android-libsparse is a library in common use by the various Android core host applications.

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

The libselinux library provides an API for SELinux applications to get and set process and file security contexts, and to obtain security policy decisions. It is required for any applications that use the SELinux API, and used by all applications that are SELinux-aware. This package also includes the core SELinux management utilities.
