-# Abseil - C++ Common Libraries
-
-The repository contains the Abseil C++ library code. Abseil is an open-source
-collection of C++ code (compliant to C++11) designed to augment the C++
-standard library.

-## About Abseil
-
-Abseil is an open-source collection of C++ library code designed to augment
-the C++ standard library. The Abseil library code is collected from Google's
-own C++ code base, has been extensively tested and used in production, and
-is the same code we depend on in our daily coding lives.
-
-In some cases, Abseil provides pieces missing from the C++ standard; in
-others, Abseil provides alternatives to the standard for special needs
-we've found through usage in the Google code base. We denote those cases
-clearly within the library code we provide you.
-
-Abseil is not meant to be a competitor to the standard library; we've
-just found that many of these utilities serve a purpose within our code
-base, and we now want to provide those resources to the C++ community as
-a whole.

-## Quickstart
-
-If you want to just get started, make sure you at least run through the
-[Abseil Quickstart](https://abseil.io/docs/cpp/quickstart). The Quickstart
-contains information about setting up your development environment, downloading
-the Abseil code, running tests, and getting a simple binary working.
-
-<a name="build"></a>
-## Building Abseil
-
-[Bazel](https://bazel.build) is the official build system for Abseil,
-which is supported on most major platforms (Linux, Windows, macOS, for example)
-and compilers. See the [quickstart](https://abseil.io/docs/cpp/quickstart) for
-more information on building Abseil using the Bazel build system.
-
-<a name="cmake"></a>
-If you require CMake support, please check the
-[CMake build instructions](CMake/README.md).
-
-## Codemap
-
-Abseil contains the following C++ library components:
-
-* [`base`](absl/base/) Abseil Fundamentals
-  <br /> The `base` library contains initialization code and other code which
-  all other Abseil code depends on. Code within `base` may not depend on any
-  other code (other than the C++ standard library).
-* [`algorithm`](absl/algorithm/)
-  <br /> The `algorithm` library contains additions to the C++ `<algorithm>`
-  library and container-based versions of such algorithms.
-* [`container`](absl/container/)
-  <br /> The `container` library contains additional STL-style containers,
-  including Abseil's unordered "Swiss table" containers.
-* [`debugging`](absl/debugging/)
-  <br /> The `debugging` library contains code useful for enabling leak
-  checks, and stacktrace and symbolization utilities.
-* [`hash`](absl/hash/)
-  <br /> The `hash` library contains the hashing framework and default hash
-  functor implementations for hashable types in Abseil.
-* [`memory`](absl/memory/)
-  <br /> The `memory` library contains C++11-compatible versions of
-  `std::make_unique()` and related memory management facilities.
-* [`meta`](absl/meta/)
-  <br /> The `meta` library contains C++11-compatible versions of type checks
-  available within C++14 and C++17 versions of the C++ `<type_traits>` library.
-* [`numeric`](absl/numeric/)
-  <br /> The `numeric` library contains C++11-compatible 128-bit integers.
-* [`strings`](absl/strings/)
-  <br /> The `strings` library contains a variety of strings routines and
-  utilities, including a C++11-compatible version of the C++17
-  `std::string_view` type.
-* [`synchronization`](absl/synchronization/)
-  <br /> The `synchronization` library contains concurrency primitives (Abseil's
-  `absl::Mutex` class, an alternative to `std::mutex`) and a variety of
-  synchronization abstractions.
-* [`time`](absl/time/)
-  <br /> The `time` library contains abstractions for computing with absolute
-  points in time, durations of time, and formatting and parsing time within
-  time zones.
-* [`types`](absl/types/)
-  <br /> The `types` library contains non-container utility types, like a
-  C++11-compatible version of the C++17 `std::optional` type.
-* [`utility`](absl/utility/)
-  <br /> The `utility` library contains utility and helper code.
