# Abseil - C++ Common Libraries\n\nThe repository contains the Abseil C++ library code. Abseil is an open-source\ncollection of C++ code (compliant to C++17) designed to augment the C++\nstandard library.\n\n## Table of Contents\n\n- [About Abseil](#about)\n- [Quickstart](#quickstart)\n- [Building Abseil](#build)\n- [Support](#support)\n- [Codemap](#codemap)\n- [Releases](#releases)\n- [License](#license)\n- [Links](#links)\n\n\n## About Abseil\n\nAbseil is an open-source collection of C++ library code designed to augment\nthe C++ standard library. The Abseil library code is collected from Google's\nown C++ code base, has been extensively tested and used in production, and\nis the same code we depend on in our daily coding lives.\n\nIn some cases, Abseil provides pieces missing from the C++ standard; in\nothers, Abseil provides alternatives to the standard for special needs\nwe've found through usage in the Google code base. We denote those cases\nclearly within the library code we provide you.\n\nAbseil is not meant to be a competitor to the standard library; we've\njust found that many of these utilities serve a purpose within our code\nbase, and we now want to provide those resources to the C++ community as\na whole.\n\n\n## Quickstart\n\nIf you want to just get started, make sure you at least run through the\n[Abseil Quickstart](https://abseil.io/docs/cpp/quickstart). The Quickstart\ncontains information about setting up your development environment, downloading\nthe Abseil code, running tests, and getting a simple binary working.\n\n\n## Building Abseil\n\n[Bazel](https://bazel.build) and [CMake](https://cmake.org/) are the official\nbuild systems for Abseil.\nSee the [quickstart](https://abseil.io/docs/cpp/quickstart) for more information\non building Abseil using the Bazel build system.\nIf you require CMake support, please check the [CMake build\ninstructions](CMake/README.md) and [CMake\nQuickstart](https://abseil.io/docs/cpp/quickstart-cmake).\n\n\n## Supp
