-## v0.3.0
-
-This update introduces new field and curve API's, and enforces they are used consistently across the library. Furthermore it makes it possible to use fields, without having to initialize elliptic curves.
-
-### Breaking Changes
-- #23 Remove unused exponent param of curves
-- #58 Add a defined API for every field type, and have minor tweaks to all fields to implement it (Thanks @alexander-zw)
-- #79 Separate field initialization from curves (Thanks @alexander-zw)
-### Features
-- #71 Add BLS12-381 (Thanks @yelhousni)
-- #80 Add clang-tidy checks to library and CI
-- #82 Convert tests to use Google test (Thanks @alexander-zw)
-- #83 Make run-clang-tidy return an error when linting fails
-- #85 Add more unit tests for fields (Thanks @alexander-zw)
-- #86 Add binary fields from [libiop](https://github.com/scipr-lab/libiop)
-- #100 Move utils in from [libiop](https://github.com/scipr-lab/libiop)
-
-### Bug fixes
-- #75 Get rid of warning for unused constant PI, in complex field
-- #78 Reduce prints when inhibit_profiling_info is set
-- #79 & #87 Use std::size_t for all code, fix bugs introduced by #58
-- #94 & #96 Fix bugs that make libff incompatible with
-  [libfqfft](https://github.com/scipr-lab/libfqfft) and [libiop](https://github.com/scipr-lab/libiop)
-- #103 Fix bugs that make libff incompatible with [libsnark](https://github.com/scipr-lab/libsnark)
-  and add more tests for the field utils
-
-## v0.2.0
-
-_Special thanks to all downstream projects upstreaming their patches!_
-
-### Breaking Changes
-- File structure changed: All field utils are now in `libff/algebra/field_utils/`, `Fp_model` is
-  now in `libff/algebra/fields/prime_base/`, and all other F_p^n fields in
-  `libff/algebra/fields/prime_extension/`.
-- The function `base_field_char()` of all fields and curves have been renamed to `field_char()`.
-- The provided fields used in curves have been moved to separate files so that they can be imported
-  separately from `[field name]_fields.hpp`. However they are still accessible from the init file.
-
-### Features
-- #20 Improve operator+ speed for alt_bn, correct the corresponding docs, and reduce code duplication.
-- #50 Add mul_by_cofactor to elliptic curve groups
-- #50 Add sage scripts for altbn and mnt curves, to verify cofactors and generators
-- #52 Change default procps build flags to work with Mac OS
-
-### Bug fixes
-- #19 Fix is_little_endian always returning true
-- #20 Fix operator+ not contributing to alt_bn_128 profiling opcount 
-- #26 Remove unused warnings in release build
-- #39 Update Travis Config for newer Ubuntu mirror defaults
-- #50 Fix incorrect mnt4 g2 generator
-- #54 Fix is_power_of_two for n > 2^32
-- #55 Throw informative error for division by zero in div_ceil

-# Contributing
-
-Thank you for considering making contributions to libff!
-
-Contributing to this repo can be done in several forms, such as participating in discussion or proposing code changes.
-To ensure a smooth workflow for all contributors, the following general procedure for contributing has been established:
-
-1) Either open or find an issue you'd like to help with
-2) Participate in thoughtful discussion on that issue
-3) If you would like to contribute:
-    * If the issue is a feature proposal, ensure that the proposal has been accepted
-    * Ensure that nobody else has already begun working on this issue. 
-    If they have, please try to contact them to collaborate
-    * If nobody has been assigned for the issue and you would like to work on it, make a comment on the issue to inform the community of your intentions to begin work. (So we can avoid duplication of efforts)
-    * We suggest using standard Github best practices for contributing: fork the repo, branch from the HEAD of develop, make some commits on your branch, and submit a PR from the branch to develop.
-    More detail on this is below
-    * Be sure to include a relevant change log entry in the Pending section of CHANGELOG.md (see file for log format)
-
-Note that for very small or clear problems (such as typos), or well isolated improvements, it is not required to an open issue to submit a PR. But be aware that for more complex problems/features touching multiple parts of the codebase, if a PR is opened before an adequate design discussion has taken place in a github issue, that PR runs a larger likelihood of being rejected.
-
-Looking for a good place to start contributing? How about checking out some ["good first issues"](https://github.com/scipr-lab/libff/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22)
-
-## Branch Structure
-
-Libff has its default branch as `develop`, which is where PRs are merged into. The `master` branch should only contain code that is part of a release. Releases will be periodically made. All other branches should be assumed to be miscellaneous feature development branches.
-
-All downstream users should be using tagged versions of the library.
-
-## How to work on a fork
-
-Please skip this section if you're familiar with contributing to open-source github projects.
-
-First, fork the repo from the github UI, and clone your fork locally (we denote
-by `<path-to-libff>` the path to your `libff` fork on your machine).
-After cloning your fork on your machine, it may be useful to add the upstream
-project as a git remote (to periodically update your fork for instance).
-You can do so by running the following command:
-```bash
-# Go to your fork cloned repository (replacing <path-to-libff> by the appropriate path)
-cd <path-to-libff>
-# Add the upstream project to your remotes
-git remote add upstream git@github.com:scipr-lab/libff.git
-# (Optional) Check the addition by inspecting your remotes
-git remote -vv
-```
-
-Then the way you make code contributions is to first think of a branch name that describes your change.
-Then do the following:
-```bash
-# Make sure your "develop" branch is up to date with the upstream repository
-git pull upstream develop
-# Create a branch for your contribution (replacing <your-branch-name> by the appropriate value)
-git checkout -b <your-branch-name>
-```
-and then work as normal on that branch, and PR'ing to upstream `develop` when you're done =)
-
-## Updating documentation
-
-All PRs should aim to leave the code more documented than it started with.
-Please don't assume that its easy to infer what the code is doing, 
-as that is usually not the case for these complex protocols unless one has been working with it recently. 
-(Even if you understand the paper!)
-
-Its often very useful to describe what is the high level view of what a code block is doing,
-and either refer to the relevant section of a paper or include a short proof/argument for why it makes sense before the actual logic.
-
-## Performance improvements
-
-All performance improvements should be accompanied with benchmarks improving, or otherwise have it be clear that things have improved.
-For some areas of the codebase, performance roughly follows the number of field multiplications, but there are also many areas where
-low level system effects such as cache locality and superscalar operations become important for performance. 
-Thus performance can often become very non-intuitive / diverge from minimizing the number of arithmetic operations.

-<h4 align="center">C++ library for Finite Fields and Elliptic Curves</h4>
-
-___libff___ is a C++ library for finite fields and elliptic curves. The library is developed by [SCIPR Lab] and contributors (see [AUTHORS] file) and is released under the MIT License (see [LICENSE] file).
-
-## Table of contents
-
-- [Directory structure](#directory-structure)
-- [Elliptic curve choices](#elliptic-curve-choices)
-- [Build guide](#build-guide)
-
-## Directory structure
-
-The directory structure is as follows:
-
-* [__libff__](libff): C++ source code, containing the following modules:
-  * [__algebra__](libff/algebra): fields and elliptic curve groups
-  * [__common__](libff/common): miscellaneous utilities
-* [__depends__](depends): dependency libraries
-
-## Elliptic curve choices
-
-The libsnark library currently provides three options:
-
-* `edwards`:
-   an instantiation based on an Edwards curve, providing 80 bits of security.
-
-* `bn128`:
-   an instantiation based on a Barreto-Naehrig curve, providing 128
-   bits of security. The underlying curve implementation is
-   \[ate-pairing], which has incorporated our patch that changes the
-   BN curve to one suitable for SNARK applications.
-
-    *   This implementation uses dynamically-generated machine code for the curve
-        arithmetic. Some modern systems disallow execution of code on the heap, and
-        will thus block this implementation.
-
-        For example, on Fedora 20 at its default settings, you will get the error
-        `zmInit ERR:can't protect` when running this code. To solve this,
-        run `sudo setsebool -P allow_execheap 1` to allow execution,
-        or use `make CURVE=ALT_BN128` instead.
-
-* `alt_bn128`:
-   an alternative to `bn128`, somewhat slower but avoids dynamic code generation.
-
-Note that `bn128` requires an x86-64 CPU while the other curve choices
-should be architecture-independent.
-
-## Build guide
-
-The library has the following dependencies:
-
-* [Boost](http://www.boost.org/)
-* [CMake](http://cmake.org/)
-* [GMP](http://gmplib.org/)
-* [libsodium](https://libsodium.gitbook.io/doc/)
-* [libprocps](http://packages.ubuntu.com/trusty/libprocps-dev) (turned off by default)
-
-The library has been tested on Linux, but it is compatible with Windows and MacOS.
-
-### Installation
-
-On Ubuntu 14.04 LTS:
-
-```
-sudo apt-get install build-essential git libboost-all-dev cmake libgmp3-dev libssl-dev libprocps3-dev pkg-config libsodium-dev
-```
-
-
-On MacOS, all of the libraries from the previous section can be installed with `brew`, except for `libprocps`, which is turned off by default.
-
-Fetch dependencies from their GitHub repos:
-
-```
-git submodule init && git submodule update
-```
-
-### Compilation
-
-To compile, starting at the project root directory, create the build directory and Makefile:
-
-```
-mkdir build && cd build
-cmake ..
-```
-
-If you are on macOS, change the cmake command to be
-
-```
-cmake .. -DOPENSSL_ROOT_DIR=$(brew --prefix openssl)
-```
-
-Other build flags include:
-| Flag | Value | Description |
-| ---- | ----- | ----------- |
-| MAKE_INSTALL_PREFIX | (your path) | Specifies the desired install location. |
-| CMAKE_BUILD_TYPE | Debug | Enables asserts. Note that tests now use gtest instead of asserts. |
-| WITH_PROCPS | ON | Enables `libprocps`, which is by default turned off since it is not supported on some systems such as MacOS. |
-
-Then, to compile and install the library, run this within the build directory:
-```
-make
-make install
-```
-
-This will install `libff.a` into `/install/path/lib`; so your application should be linked using `-L/install/path/lib -lff`. It also installs the requisite headers into `/install/path/include`; so your application should be compiled using `-I/install/path/include`.
-
-## Testing
-
-To build and execute the tests for this library, run:
-```
-make check
-```
-
-## Code formatting and linting
-
-To run clang-tidy on this library, specify the variable `USE_CLANG_TIDY` (eg. `cmake .. -D USE_CLANG_TIDY=ON`).
-Then, run:
-```
-make clang-tidy
-```
-
-One can specify which clang-tidy checks to run and which files to run clang-tidy on using the `.clang-tidy` file in the root directory of the project.
-
-## Profile
-
-To compile the multi-exponentiation profiler in this library, run:
-```
-make profile
-```
-The resulting profiler is named `multiexp_profile` and can be found in the `libff` folder under the build directory.

-High-Speed Software Implementation of the Optimal Ate Pairing over Barreto-Naehrig Curves
-=============
-
-This library provides functionality to compute the optimal ate pairing over Barreto-Naehrig (BN) curves.
-It is released under the [BSD 3-Clause License](http://opensource.org/licenses/BSD-3-Clause).
-
-Now I'm developing a new pairing library [mcl](https://github.com/herumi/mcl/), which is more portable and supports larger primes than this library though it is a little slower.
-
-History
--------------
-
-* 2015/May/15: add [java api](java/java.md)
-* 2014/Jun/15: support a BN curve for SNARKs, incorporating code from [libsnark](https://github.com/scipr-lab/libsnark)
-* 2013/Jun/02: support `mulx` on [Haswell](http://en.wikipedia.org/wiki/Haswell_%28microarchitecture%29)
-* 2013/Mar/08: add elliptic curve class
-* 2012/Jan/30: rewrite ate pairing according to [Faster explicit formulas for computing pairings over ordinary curves](http://www.patricklonga.bravehost.com/speed_pairing.html)
-* 2010/Sep/8: change twist xi from u + 12 to u
-* 2010/Jul/15: use cyclotomic squaring for final exponentiation
-* 2010/Jun/18: first release
-
-Overview
--------------
-
-The following two BN curves are supported:
-
-1. a BN curve over the 254-bit prime p = 36z^4 + 36z^3 + 24z^2 + 6z + 1 where z = -(2^62 + 2^55 + 1); and
-2. a BN curve over a 254-bit prime p such that n := p + 1 - t has high 2-adicity.
-
-By default, the first curve (we call it as CurveFp254BNb) is used; when setting the flag `SUPPORT_SNARK`, the second curve (we call it as CurveSNARK) is used instead.
-
-* __CurveFp254BNb__
-The value of z is found by [\[NASKM\]](http://dx.doi.org/10.1007/978-3-540-85538-5_13) first.
-The curve instantiated by z is investigated by [\[PSNB\]](http://eprint.iacr.org/2010/429) for an efficient implementation.
-Our library implements a fast algorithm, which is proposed by [\[AKLGL\]](http://eprint.iacr.org/2010/526) for this curve.
-The performance of this library is competitive to the state-of-the-art implementation report in [\[ABLR\]](http://sac2013.irmacs.sfu.ca/slides/s1.pdf).
-
-* __CurveSNARK__
-Support for the second curve builds on code provided by [SCIPR Lab](http://www.scipr-lab.org/) in [libsnark](https://github.com/scipr-lab/libsnark). The curve was specifically selected for speeding up __Succinct Non-interactive ARguments of Knowledge__ (SNARKs), which benefit from its high 2-adicity (see [\[BCGTV13\]](http://eprint.iacr.org/2013/507) and [\[BCTV14\]](http://eprint.iacr.org/2013/879)).
-
-Pairing computations on the first curve are more efficient, and the performance numbers reported below (and in our papers) are achieved using this curve (which is prefered for applications that do not benefit from high 2-adicity).
-Note that the old parameters in \[BDMOHT\] are not used now.
-
-
-Parameters
--------------
-
-The curve equation for a BN curve is:
-
-	E/Fp: y^2 = x^3 + b .
-
-The two supported BN curves have the following parameters:
-
-1. b = 2 and p = 16798108731015832284940804142231733909889187121439069848933715426072753864723; and
-2. b = 3 and p = 21888242871839275222246405745257275088696311157297823662689037894645226208583.
-
-As usual,
-
-* the cyclic group G1 (aka Ec1) is instantiated as E(Fp)[n] where n := p + 1 - t;
-* the cyclic group G2 (aka Ec2) is instantiated as the inverse image of E'(Fp^2)[n] under a twisting isomorphism from E' to E; and
-* the pairing e: G1 x G2 -> Fp12 is the optimal ate pairing.
-
-The field Fp12 is constructed via the following tower:
-
-* Fp2 = Fp[u] / (u^2 + 1)
-* Fp6 = Fp2[v] / (v^3 - Xi) where Xi = u + 1
-* Fp12 = Fp6[w] / (w^2 - v)
-
-Requirements
--------------
-
-* OS: 64-bit Windows; 64-bit Linux; Mac OS X
-* CPU: x64 Intel; AMD processor
-* C++ compiler: Visual Studio 2012; gcc 4.4.1 or later
-
-
-Build instructions
--------------
-
-### Windows
-
-    > git clone git://github.com/herumi/xbyak.git
-    > git clone git://github.com/herumi/ate-pairing.git
-    > git clone git://github.com/herumi/cybozulib-ext.git ; compiled binary of mpir
-
-Open `ate/ate.sln` and compile `test_bn` with Release mode. The produced binary is `ate/x64/Release/test_bn.exe`.
-
-### Cygwin
-
-Install `mingw64-x86_64-gcc-g++` (run Cygwin setup and search `mingw64`). Then use the following commands:
-
-    PATH=/usr/x86_64-w64-mingw32/sys-root/mingw/bin/:$PATH
-    make -j
-    test/bn.exe
-
-Note that `test/bn.exe` uses `mulx` if possible; if you do not want to use it, run the executable as `test/bn.exe -mulx 0`. (This allows you to verify the difference with/without mulx on Haswell.)
-
-### Linux
-
-Use the following commands:
-
-    $ git clone git://github.com/herumi/xbyak.git
-    $ git clone git://github.com/herumi/ate-pairing.git
-    $ cd ate-pairing
-    $ make -j
-    $ test/bn
-
-The library [xbyak](https://github.com/herumi/xbyak) is a x86/x86-64 JIT assembler for C++, developed for efficient pairing implementations. (See also [this webpage](http://homepage1.nifty.com/herumi/soft/xbyak_e.html).) Note that binaries other than `test/bn` are used for testing purposes only.
-
-* This implementation uses dynamically-generated code, so you will get the error
-`zmInit ERR:can't protect` if execution of code on the heap is disallowed by
-some modern systems.
-For example, on Fedora 20, run `sudo setsebool -P allow_execheap 1` to allow execution to solve this.
-
-By the default, the first BN curve is used. If instead you want to use the second BN curve (specialized to SNARKs), modify the fourth line above to:
-
-    $ make -j SUPPORT_SNARK=1
-
-* REMARK. You *defined* `BN_SUPPORT_SNARK` macro for a compile when if you use a library(libzm.a) made by `SUPPORT_SNARK=1`.
-
-
-Usage
--------------
-
-See the function `sample2()` in [sample.cpp](https://github.com/herumi/ate-pairing/blob/master/test/sample.cpp). Also, use can use `mpz_class` for scalar multiplication of points on the elliptic curves,
-if `MIE_ATE_USE_GMP` is defined. For instance:
-
-    using namespace bn;
-    Param::init();
-    const Ec2 g2(...);
-    const Ec1 g1(...);
-    mpz_class a("123456789");
-    mpz_class b("98765432");
-    Ec1 g1a = g1 * a;
-    Ec2 g2b = g2 * b;
-    Fp12 e;
-    opt_atePairing(e, g2b, g1a);
-
-Usage for Java
--------------
-See [java.md](java/java.md).
-A sample code is [BN254Test.java](java/BN254Test.java).
-
-Operation costs
--------------
-
-Let mu be the cost of _unreduced multiplication_ producing double-precision result (i.e., 256-bit int x 256-bit int to 512-bit int); and let r be the cost of _modular reduction_ of double-precision integers (i.e., 512-bit int to 256-bit int in Fp). Then, for us,
-
-* Fp::mul = mu + r
-* Fp2::mul = 3mu + 2r
-* Fp2::square = 2mu + 2r
-
-Next, we compare the costs of our library with the one of [\[AKLGL10\]](http://eprint.iacr.org/2010/526):

-
-Note: [\[Table 2 in p. 17, AKLGL10\]](http://eprint.iacr.org/2010/526) does not contain the cost of (m, r) so we have added the costs of (282m + 6mu + 4r) and (30m + 75mu + 50r) to ML and FE respectively.
-
-Finally, at the moment, our implementation does not support the algorithm in [PSNB10](https://eprint.iacr.org/2010/429).

-Benchmark
--------------
-
-The cost of a pairing is __1.17M__ clock cycles on Core i7 4700MQ (Haswell) 2.4GHz processor with TurboBoost disabled. Below, we also include clock cycle counts on Core i7 2600 3.4GHz, Xeon X5650 2.6GHz, and Core i7 4700MQ 2.4GHz.
-The formal benchmark is written in \[ZPMRTH\].

-# How to become a contributor and submit your own code
-
-## Contributor License Agreements
-
-We'd love to accept your patches! Before we can take them, we
-have to jump a couple of legal hurdles.
-
-Please fill out either the individual or corporate Contributor License Agreement
-(CLA).
-
-  * If you are an individual writing original source code and you're sure you
-    own the intellectual property, then you'll need to sign an
-    [individual CLA](https://developers.google.com/open-source/cla/individual).
-  * If you work for a company that wants to allow you to contribute your work,
-    then you'll need to sign a
-    [corporate CLA](https://developers.google.com/open-source/cla/corporate).
-
-Follow either of the two links above to access the appropriate CLA and
-instructions for how to sign and return it. Once we receive it, we'll be able to
-accept your pull requests.
-
-## Contributing A Patch
-
-1. Submit an issue describing your proposed change to the
-   [issue tracker](https://github.com/google/googletest).
-1. Please don't mix more than one logical change per submittal,
-   because it makes the history hard to follow. If you want to make a
-   change that doesn't have a corresponding issue in the issue
-   tracker, please create one.
-1. Also, coordinate with team members that are listed on the issue in
-   question. This ensures that work isn't being duplicated and
-   communicating your plan early also generally leads to better
-   patches.
-1. If your proposed change is accepted, and you haven't already done so, sign a
-   Contributor License Agreement (see details above).
-1. Fork the desired repo, develop and test your code changes.
-1. Ensure that your code adheres to the existing style in the sample to which
-   you are contributing.
-1. Ensure that your code has an appropriate set of unit tests which all pass.
-1. Submit a pull request.
-
-If you are a Googler, it is preferable to first create an internal change and
-have it reviewed and submitted, and then create an upstreaming pull
-request here. 
-
-## The Google Test and Google Mock Communities ##
-
-The Google Test community exists primarily through the
-[discussion group](http://groups.google.com/group/googletestframework)
-and the GitHub repository.
-Likewise, the Google Mock community exists primarily through their own
-[discussion group](http://groups.google.com/group/googlemock).
-You are definitely encouraged to contribute to the
-discussion and you can also help us to keep the effectiveness of the
-group high by following and promoting the guidelines listed here.
-
-### Please Be Friendly ###
-
-Showing courtesy and respect to others is a vital part of the Google
-culture, and we strongly encourage everyone participating in Google
-Test development to join us in accepting nothing less. Of course,
-being courteous is not the same as failing to constructively disagree
-with each other, but it does mean that we should be respectful of each
-other when enumerating the 42 technical reasons that a particular
-proposal may not be the best choice. There's never a reason to be
-antagonistic or dismissive toward anyone who is sincerely trying to
-contribute to a discussion.
-
-Sure, C++ testing is serious business and all that, but it's also
-a lot of fun. Let's keep it that way. Let's strive to be one of the
-friendliest communities in all of open source.
-
-As always, discuss Google Test in the official GoogleTest discussion group.
-You don't have to actually submit code in order to sign up. Your participation
-itself is a valuable contribution.
-
-## Style
-
-To keep the source consistent, readable, diffable and easy to merge,
-we use a fairly rigid coding style, as defined by the [google-styleguide](https://github.com/google/styleguide) project.  All patches will be expected
-to conform to the style outlined [here](https://google.github.io/styleguide/cppguide.html).
-
-## Requirements for Contributors ###
-
-If you plan to contribute a patch, you need to build Google Test,
-Google Mock, and their own tests from a git checkout, which has
-further requirements:
-
-  * [Python](https://www.python.org/) v2.3 or newer (for running some of
-    the tests and re-generating certain source files from templates)
-  * [CMake](https://cmake.org/) v2.6.4 or newer
-  * [GNU Build System](https://en.wikipedia.org/wiki/GNU_Build_System)
-    including automake (>= 1.9), autoconf (>= 2.59), and
-    libtool / libtoolize.
-
-## Developing Google Test ##
-
-This section discusses how to make your own changes to Google Test.

-### Testing Google Test Itself ###
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you can use CMake:
-
-    mkdir mybuild
-    cd mybuild
-    cmake -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Make sure you have Python installed, as some of Google Test's tests
-are written in Python.  If the cmake command complains about not being
-able to find Python (`Could NOT find PythonInterp (missing:
-PYTHON_EXECUTABLE)`), try telling it explicitly where your Python
-executable can be found:
-
-    cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Next, you can build Google Test and all of its own tests.  On \*nix,
-this is usually done by 'make'.  To run the tests, do
-
-    make test
-
-All tests should pass.
-
-### Regenerating Source Files ##
-
-Some of Google Test's source files are generated from templates (not
-in the C++ sense) using a script.
-For example, the
-file include/gtest/internal/gtest-type-util.h.pump is used to generate
-gtest-type-util.h in the same directory.
-
-You don't need to worry about regenerating the source files
-unless you need to modify them.  You would then modify the
-corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)'
-generator script.  See the [Pump Manual](googletest/docs/PumpManual.md).
-
-## Developing Google Mock ###
-
-This section discusses how to make your own changes to Google Mock.
-
-#### Testing Google Mock Itself ####
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you'll need Autotools.  First, make sure you have followed
-the instructions above to configure Google Mock.
-Then, create a build output directory and enter it.  Next,
-
-    ${GMOCK_DIR}/configure  # try --help for more info
-
-Once you have successfully configured Google Mock, the build steps are
-standard for GNU-style OSS packages.
-
-    make        # Standard makefile following GNU conventions
-    make check  # Builds and runs all tests - all should pass.
-
-Note that when building your project against Google Mock, you are building
-against Google Test as well.  There is no need to configure Google Test
-separately.

-
-Welcome to **Google Test**, Google's C++ test framework!
-
-This repository is a merger of the formerly separate GoogleTest and
-GoogleMock projects. These were so closely related that it makes sense to
-maintain and release them together.
-
-Please see the project page above for more information as well as the
-mailing list for questions, discussions, and development.  There is
-also an IRC channel on [OFTC](https://webchat.oftc.net/) (irc.oftc.net) #gtest available.  Please
-join us!
-
-Getting started information for **Google Test** is available in the 
-[Google Test Primer](googletest/docs/Primer.md) documentation.
-
-**Google Mock** is an extension to Google Test for writing and using C++ mock
-classes.  See the separate [Google Mock documentation](googlemock/README.md).
-
-More detailed documentation for googletest (including build instructions) are
-in its interior [googletest/README.md](googletest/README.md) file.
-
-## Features ##
-
-  * An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
-  * Test discovery.
-  * A rich set of assertions.
-  * User-defined assertions.
-  * Death tests.
-  * Fatal and non-fatal failures.
-  * Value-parameterized tests.
-  * Type-parameterized tests.
-  * Various options for running the tests.
-  * XML test report generation.
-
-## Platforms ##
-
-Google test has been used on a variety of platforms:
-
-  * Linux
-  * Mac OS X
-  * Windows
-  * Cygwin
-  * MinGW
-  * Windows Mobile
-  * Symbian
-
-## Who Is Using Google Test? ##
-
-In addition to many internal projects at Google, Google Test is also used by
-the following notable projects:
-
-  * The [Chromium projects](http://www.chromium.org/) (behind the Chrome
-    browser and Chrome OS).
-  * The [LLVM](http://llvm.org/) compiler.
-  * [Protocol Buffers](https://github.com/google/protobuf), Google's data
-    interchange format.
-  * The [OpenCV](http://opencv.org/) computer vision library.
-  * [tiny-dnn](https://github.com/tiny-dnn/tiny-dnn): header only, dependency-free deep learning framework in C++11.
-
-## Related Open Source Projects ##
-
-[GTest Runner](https://github.com/nholthaus/gtest-runner) is a Qt5 based automated test-runner and Graphical User Interface with powerful features for Windows and Linux platforms.
-
-[Google Test UI](https://github.com/ospector/gtest-gbar) is test runner that runs
-your test binary, allows you to track its progress via a progress bar, and
-displays a list of test failures. Clicking on one shows failure text. Google
-Test UI is written in C#.
-
-[GTest TAP Listener](https://github.com/kinow/gtest-tap-listener) is an event
-listener for Google Test that implements the
-[TAP protocol](https://en.wikipedia.org/wiki/Test_Anything_Protocol) for test
-result output. If your test runner understands TAP, you may find it useful.
-
-[gtest-parallel](https://github.com/google/gtest-parallel) is a test runner that
-runs tests from your binary in parallel to provide significant speed-up.
-
-## Requirements ##
-
-Google Test is designed to have fairly minimal requirements to build
-and use with your projects, but there are some.  Currently, we support
-Linux, Windows, Mac OS X, and Cygwin.  We will also make our best
-effort to support other platforms (e.g. Solaris, AIX, and z/OS).
-However, since core members of the Google Test project have no access
-to these platforms, Google Test may have outstanding issues there.  If
-you notice any problems on your platform, please notify
-[googletestframework@googlegroups.com](https://groups.google.com/forum/#!forum/googletestframework). Patches for fixing them are
-even more welcome!
-
-### Linux Requirements ###
-
-These are the base requirements to build and use Google Test from a source
-package (as described below):
-
-  * GNU-compatible Make or gmake
-  * POSIX-standard shell
-  * POSIX(-2) Regular Expressions (regex.h)
-  * A C++98-standard-compliant compiler
-
-### Windows Requirements ###
-
-  * Microsoft Visual C++ 2015 or newer
-
-### Cygwin Requirements ###
-
-  * Cygwin v1.5.25-14 or newer
-
-### Mac OS X Requirements ###

@@ -1,126 +0,0 @@
-Changes for 1.7.0:
-
-* All new improvements in Google Test 1.7.0.
-* New feature: matchers DoubleNear(), FloatNear(),
-  NanSensitiveDoubleNear(), NanSensitiveFloatNear(),
-  UnorderedElementsAre(), UnorderedElementsAreArray(), WhenSorted(),
-  WhenSortedBy(), IsEmpty(), and SizeIs().
-* Improvement: Google Mock can now be built as a DLL.
-* Improvement: when compiled by a C++11 compiler, matchers AllOf()
-  and AnyOf() can accept an arbitrary number of matchers.
-* Improvement: when compiled by a C++11 compiler, matchers
-  ElementsAreArray() can accept an initializer list.
-* Improvement: when exceptions are enabled, a mock method with no
-  default action now throws instead crashing the test.
-* Improvement: added class testing::StringMatchResultListener to aid
-  definition of composite matchers.
-* Improvement: function return types used in MOCK_METHOD*() macros can
-  now contain unprotected commas.
-* Improvement (potentially breaking): EXPECT_THAT() and ASSERT_THAT()
-  are now more strict in ensuring that the value type and the matcher
-  type are compatible, catching potential bugs in tests.
-* Improvement: Pointee() now works on an optional<T>.
-* Improvement: the ElementsAreArray() matcher can now take a vector or
-  iterator range as input, and makes a copy of its input elements
-  before the conversion to a Matcher.
-* Improvement: the Google Mock Generator can now generate mocks for
-  some class templates.
-* Bug fix: mock object destruction triggerred by another mock object's
-  destruction no longer hangs.
-* Improvement: Google Mock Doctor works better with newer Clang and
-  GCC now.
-* Compatibility fixes.
-* Bug/warning fixes.
-
-Changes for 1.6.0:
-
-* Compilation is much faster and uses much less memory, especially
-  when the constructor and destructor of a mock class are moved out of
-  the class body.
-* New matchers: Pointwise(), Each().
-* New actions: ReturnPointee() and ReturnRefOfCopy().
-* CMake support.
-* Project files for Visual Studio 2010.
-* AllOf() and AnyOf() can handle up-to 10 arguments now.
-* Google Mock doctor understands Clang error messages now.
-* SetArgPointee<> now accepts string literals.
-* gmock_gen.py handles storage specifier macros and template return
-  types now.
-* Compatibility fixes.
-* Bug fixes and implementation clean-ups.
-* Potentially incompatible changes: disables the harmful 'make install'
-  command in autotools.
-
-Potentially breaking changes:
-
-* The description string for MATCHER*() changes from Python-style
-  interpolation to an ordinary C++ string expression.
-* SetArgumentPointee is deprecated in favor of SetArgPointee.
-* Some non-essential project files for Visual Studio 2005 are removed.
-
-Changes for 1.5.0:
-
- * New feature: Google Mock can be safely used in multi-threaded tests
-   on platforms having pthreads.
- * New feature: function for printing a value of arbitrary type.
- * New feature: function ExplainMatchResult() for easy definition of
-   composite matchers.
- * The new matcher API lets user-defined matchers generate custom
-   explanations more directly and efficiently.
- * Better failure messages all around.
- * NotNull() and IsNull() now work with smart pointers.
- * Field() and Property() now work when the matcher argument is a pointer
-   passed by reference.
- * Regular expression matchers on all platforms.
- * Added GCC 4.0 support for Google Mock Doctor.
- * Added gmock_all_test.cc for compiling most Google Mock tests
-   in a single file.
- * Significantly cleaned up compiler warnings.
- * Bug fixes, better test coverage, and implementation clean-ups.
-
- Potentially breaking changes:
-
- * Custom matchers defined using MatcherInterface or MakePolymorphicMatcher()
-   need to be updated after upgrading to Google Mock 1.5.0; matchers defined
-   using MATCHER or MATCHER_P* aren't affected.
- * Dropped support for 'make install'.
-
-Changes for 1.4.0 (we skipped 1.2.* and 1.3.* to match the version of
-Google Test):
-
- * Works in more environments: Symbian and minGW, Visual C++ 7.1.
- * Lighter weight: comes with our own implementation of TR1 tuple (no
-   more dependency on Boost!).
- * New feature: --gmock_catch_leaked_mocks for detecting leaked mocks.
- * New feature: ACTION_TEMPLATE for defining templatized actions.
- * New feature: the .After() clause for specifying expectation order.
- * New feature: the .With() clause for specifying inter-argument
-   constraints.
- * New feature: actions ReturnArg<k>(), ReturnNew<T>(...), and
-   DeleteArg<k>().
- * New feature: matchers Key(), Pair(), Args<...>(), AllArgs(), IsNull(),
-   and Contains().
- * New feature: utility class MockFunction<F>, useful for checkpoints, etc.
- * New feature: functions Value(x, m) and SafeMatcherCast<T>(m).
- * New feature: copying a mock object is rejected at compile time.
- * New feature: a script for fusing all Google Mock and Google Test
-   source files for easy deployment.
- * Improved the Google Mock doctor to diagnose more diseases.
- * Improved the Google Mock generator script.
- * Compatibility fixes for Mac OS X and gcc.
- * Bug fixes and implementation clean-ups.
-
-Changes for 1.1.0:
-
- * New feature: ability to use Google Mock with any testing framework.
- * New feature: macros for easily defining new matchers
- * New feature: macros for easily defining new actions.
- * New feature: more container matchers.
- * New feature: actions for accessing function arguments and throwing
-   exceptions.
- * Improved the Google Mock doctor script for diagnosing compiler errors.
- * Bug fixes and implementation clean-ups.
-
-Changes for 1.0.0:

-## Google Mock ##
-
-The Google C++ mocking framework.
-
-### Overview ###
-
-Google's framework for writing and using C++ mock classes.
-It can help you derive better designs of your system and write better tests.
-
-It is inspired by:
-
-  * [jMock](http://www.jmock.org/),
-  * [EasyMock](http://www.easymock.org/), and
-  * [Hamcrest](http://code.google.com/p/hamcrest/),
-
-and designed with C++'s specifics in mind.
-
-Google mock:
-
-  * lets you create mock classes trivially using simple macros.
-  * supports a rich set of matchers and actions.
-  * handles unordered, partially ordered, or completely ordered expectations.
-  * is extensible by users.
-
-We hope you find it useful!
-
-### Features ###
-
-  * Provides a declarative syntax for defining mocks.
-  * Can easily define partial (hybrid) mocks, which are a cross of real
-    and mock objects.
-  * Handles functions of arbitrary types and overloaded functions.
-  * Comes with a rich set of matchers for validating function arguments.
-  * Uses an intuitive syntax for controlling the behavior of a mock.
-  * Does automatic verification of expectations (no record-and-replay needed).
-  * Allows arbitrary (partial) ordering constraints on
-    function calls to be expressed,.
-  * Lets an user extend it by defining new matchers and actions.
-  * Does not use exceptions.
-  * Is easy to learn and use.
-
-Please see the project page above for more information as well as the
-mailing list for questions, discussions, and development.  There is
-also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please
-join us!
-
-Please note that code under [scripts/generator](scripts/generator/) is
-from [cppclean](http://code.google.com/p/cppclean/) and released under
-the Apache License, which is different from Google Mock's license.
-
-## Getting Started ##
-
-If you are new to the project, we suggest that you read the user
-documentation in the following order:
-
-  * Learn the [basics](../../master/googletest/docs/Primer.md) of
-    Google Test, if you choose to use Google Mock with it (recommended).
-  * Read [Google Mock for Dummies](../../master/googlemock/docs/ForDummies.md).
-  * Read the instructions below on how to build Google Mock.
-
-You can also watch Zhanyong's [talk](http://www.youtube.com/watch?v=sYpCyLI47rM) on Google Mock's usage and implementation.
-
-Once you understand the basics, check out the rest of the docs:
-
-  * [CheatSheet](../../master/googlemock/docs/CheatSheet.md) - all the commonly used stuff
-    at a glance.
-  * [CookBook](../../master/googlemock/docs/CookBook.md) - recipes for getting things done,
-    including advanced techniques.
-
-If you need help, please check the
-[KnownIssues](docs/KnownIssues.md) and
-[FrequentlyAskedQuestions](docs/FrequentlyAskedQuestions.md) before
-posting a question on the
-[discussion group](http://groups.google.com/group/googlemock).
-
-
-### Using Google Mock Without Google Test ###
-
-Google Mock is not a testing framework itself.  Instead, it needs a
-testing framework for writing tests.  Google Mock works seamlessly
-with [Google Test](https://github.com/google/googletest), but
-you can also use it with [any C++ testing framework](../../master/googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework).
-
-### Requirements for End Users ###
-
-Google Mock is implemented on top of [Google Test](
-http://github.com/google/googletest/), and depends on it.
-You must use the bundled version of Google Test when using Google Mock.
-
-You can also easily configure Google Mock to work with another testing
-framework, although it will still need Google Test.  Please read
-["Using_Google_Mock_with_Any_Testing_Framework"](
-    ../../master/googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework)
-for instructions.
-
-Google Mock depends on advanced C++ features and thus requires a more
-modern compiler. The following are needed to use Google Mock:
-
-#### Linux Requirements ####
-
-  * GNU-compatible Make or "gmake"
-  * POSIX-standard shell
-  * POSIX(-2) Regular Expressions (regex.h)
-  * C++98-standard-compliant compiler (e.g. GCC 3.4 or newer)
-
-#### Windows Requirements ####
-
-  * Microsoft Visual C++ 8.0 SP1 or newer
-
-#### Mac OS X Requirements ####
-
-  * Mac OS X 10.4 Tiger or newer
-  * Developer Tools Installed
-
-### Requirements for Contributors ###
-
-We welcome patches. If you plan to contribute a patch, you need to
-build Google Mock and its tests, which has further requirements:
-
-  * Automake version 1.9 or newer
-  * Autoconf version 2.59 or newer
-  * Libtool / Libtoolize
-  * Python version 2.3 or newer (for running some of the tests and
-    re-generating certain source files from templates)
-
-### Building Google Mock ###
-
-#### Using CMake ####
-
-If you have CMake available, it is recommended that you follow the
-[build instructions][gtest_cmakebuild]
-as described for Google Test. 
-
-If are using Google Mock with an
-existing CMake project, the section
-[Incorporating Into An Existing CMake Project][gtest_incorpcmake]
-may be of particular interest. 
-To make it work for Google Mock you will need to change 
-
-    target_link_libraries(example gtest_main)
-
-to 
-
-    target_link_libraries(example gmock_main)
-    
-This works because `gmock_main` library is compiled with Google Test.
-However, it does not automatically add Google Test includes.
-Therefore you will also have to change
-
-    if (CMAKE_VERSION VERSION_LESS 2.8.11)
-      include_directories("${gtest_SOURCE_DIR}/include")
-    endif()
-
-to
-
-    if (CMAKE_VERSION VERSION_LESS 2.8.11)
-      include_directories(BEFORE SYSTEM
-        "${gtest_SOURCE_DIR}/include" "${gmock_SOURCE_DIR}/include")
-    else()
-      target_include_directories(gmock_main SYSTEM BEFORE INTERFACE
-        "${gtest_SOURCE_DIR}/include" "${gmock_SOURCE_DIR}/include")
-    endif()
-
-This will addtionally mark Google Mock includes as system, which will 
-silence compiler warnings when compiling your tests using clang with 
-`-Wpedantic -Wall -Wextra -Wconversion`.
-
-
-#### Preparing to Build (Unix only) ####
-
-If you are using a Unix system and plan to use the GNU Autotools build
-system to build Google Mock (described below), you'll need to
-configure it now.
-
-To prepare the Autotools build system:
-
-    cd googlemock
-    autoreconf -fvi
-
-To build Google Mock and your tests that use it, you need to tell your
-build system where to find its headers and source files.  The exact
-way to do it depends on which build system you use, and is usually
-straightforward.
-
-This section shows how you can integrate Google Mock into your
-existing build system.
-
-Suppose you put Google Mock in directory `${GMOCK_DIR}` and Google Test
-in `${GTEST_DIR}` (the latter is `${GMOCK_DIR}/gtest` by default).  To
-build Google Mock, create a library build target (or a project as
-called by Visual Studio and Xcode) to compile
-
-    ${GTEST_DIR}/src/gtest-all.cc and ${GMOCK_DIR}/src/gmock-all.cc
-
-with
-
-    ${GTEST_DIR}/include and ${GMOCK_DIR}/include
-
-in the system header search path, and
-
-    ${GTEST_DIR} and ${GMOCK_DIR}
-
-in the normal header search path.  Assuming a Linux-like system and gcc,
-something like the following will do:
-
-    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-        -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-        -pthread -c ${GTEST_DIR}/src/gtest-all.cc
-    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-        -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-        -pthread -c ${GMOCK_DIR}/src/gmock-all.cc
-    ar -rv libgmock.a gtest-all.o gmock-all.o
-
-(We need -pthread as Google Test and Google Mock use threads.)
-
-Next, you should compile your test source file with
-${GTEST\_DIR}/include and ${GMOCK\_DIR}/include in the header search
-path, and link it with gmock and any other necessary libraries:
-
-    g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \
-        -pthread path/to/your_test.cc libgmock.a -o your_test
-
-As an example, the make/ directory contains a Makefile that you can
-use to build Google Mock on systems where GNU make is available
-(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
-Mock's own tests.  Instead, it just builds the Google Mock library and
-a sample test.  You can use it as a starting point for your own build
-script.
-
-If the default settings are correct for your environment, the
-following commands should succeed:
-
-    cd ${GMOCK_DIR}/make
-    make
-    ./gmock_test
-
-If you see errors, try to tweak the contents of
-[make/Makefile](make/Makefile) to make them go away.
-
-### Windows ###
-
-The msvc/2005 directory contains VC++ 2005 projects and the msvc/2010
-directory contains VC++ 2010 projects for building Google Mock and
-selected tests.
-
-Change to the appropriate directory and run "msbuild gmock.sln" to
-build the library and tests (or open the gmock.sln in the MSVC IDE).
-If you want to create your own project to use with Google Mock, you'll
-have to configure it to use the `gmock_config` propety sheet.  For that:
-
- * Open the Property Manager window (View | Other Windows | Property Manager)
- * Right-click on your project and select "Add Existing Property Sheet..."
- * Navigate to `gmock_config.vsprops` or `gmock_config.props` and select it.
- * In Project Properties | Configuration Properties | General | Additional
-   Include Directories, type <path to Google Mock>/include.
-
-### Tweaking Google Mock ###
-
-Google Mock can be used in diverse environments.  The default
-configuration may not work (or may not work well) out of the box in
-some environments.  However, you can easily tweak Google Mock by
-defining control macros on the compiler command line.  Generally,
-these macros are named like `GTEST_XYZ` and you define them to either 1
-or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below.  For a complete list,
-see file [${GTEST\_DIR}/include/gtest/internal/gtest-port.h](
-../googletest/include/gtest/internal/gtest-port.h).
-
-### Choosing a TR1 Tuple Library ###
-
-Google Mock uses the C++ Technical Report 1 (TR1) tuple library
-heavily.  Unfortunately TR1 tuple is not yet widely available with all
-compilers.  The good news is that Google Test 1.4.0+ implements a
-subset of TR1 tuple that's enough for Google Mock's need.  Google Mock
-will automatically use that implementation when the compiler doesn't
-provide TR1 tuple.
-
-Usually you don't need to care about which tuple library Google Test
-and Google Mock use.  However, if your project already uses TR1 tuple,
-you need to tell Google Test and Google Mock to use the same TR1 tuple
-library the rest of your project uses, or the two tuple
-implementations will clash.  To do that, add
-
-    -DGTEST_USE_OWN_TR1_TUPLE=0
-
-to the compiler flags while compiling Google Test, Google Mock, and
-your tests.  If you want to force Google Test and Google Mock to use
-their own tuple library, just add
-
-    -DGTEST_USE_OWN_TR1_TUPLE=1
-
-to the compiler flags instead.
-
-If you want to use Boost's TR1 tuple library with Google Mock, please
-refer to the Boost website (http://www.boost.org/) for how to obtain
-it and set it up.
-
-### As a Shared Library (DLL) ###
-
-Google Mock is compact, so most users can build and link it as a static
-library for the simplicity.  Google Mock can be used as a DLL, but the
-same DLL must contain Google Test as well.  See
-[Google Test's README][gtest_readme]
-for instructions on how to set up necessary compiler settings.
-
-### Tweaking Google Mock ###
-
-Most of Google Test's control macros apply to Google Mock as well.
-Please see [Google Test's README][gtest_readme] for how to tweak them.
-
-### Upgrading from an Earlier Version ###
-
-We strive to keep Google Mock releases backward compatible.
-Sometimes, though, we have to make some breaking changes for the
-users' long-term benefits.  This section describes what you'll need to
-do if you are upgrading from an earlier version of Google Mock.
-
-#### Upgrading from 1.1.0 or Earlier ####
-
-You may need to explicitly enable or disable Google Test's own TR1
-tuple library.  See the instructions in section "[Choosing a TR1 Tuple
-Library](../googletest/#choosing-a-tr1-tuple-library)".
-
-#### Upgrading from 1.4.0 or Earlier ####
-
-On platforms where the pthread library is available, Google Test and
-Google Mock use it in order to be thread-safe.  For this to work, you
-may need to tweak your compiler and/or linker flags.  Please see the
-"[Multi-threaded Tests](../googletest#multi-threaded-tests
-)" section in file Google Test's README for what you may need to do.
-
-If you have custom matchers defined using `MatcherInterface` or
-`MakePolymorphicMatcher()`, you'll need to update their definitions to
-use the new matcher API (
-[monomorphic](./docs/CookBook.md#writing-new-monomorphic-matchers),
-[polymorphic](./docs/CookBook.md#writing-new-polymorphic-matchers)).
-Matchers defined using `MATCHER()` or `MATCHER_P*()` aren't affected.
-
-Happy testing!

-# Defining a Mock Class #
-
-## Mocking a Normal Class ##
-
-Given
-```
-class Foo {
-  ...
-  virtual ~Foo();
-  virtual int GetSize() const = 0;
-  virtual string Describe(const char* name) = 0;
-  virtual string Describe(int type) = 0;
-  virtual bool Process(Bar elem, int count) = 0;
-};
-```
-(note that `~Foo()` **must** be virtual) we can define its mock as
-```
-#include "gmock/gmock.h"
-
-class MockFoo : public Foo {
-  MOCK_CONST_METHOD0(GetSize, int());
-  MOCK_METHOD1(Describe, string(const char* name));
-  MOCK_METHOD1(Describe, string(int type));
-  MOCK_METHOD2(Process, bool(Bar elem, int count));
-};
-```
-
-To create a "nice" mock object which ignores all uninteresting calls,
-or a "strict" mock object, which treats them as failures:
-```
-NiceMock<MockFoo> nice_foo;     // The type is a subclass of MockFoo.
-StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
-```
-
-## Mocking a Class Template ##
-
-To mock
-```
-template <typename Elem>
-class StackInterface {
- public:
-  ...
-  virtual ~StackInterface();
-  virtual int GetSize() const = 0;
-  virtual void Push(const Elem& x) = 0;
-};
-```
-(note that `~StackInterface()` **must** be virtual) just append `_T` to the `MOCK_*` macros:
-```
-template <typename Elem>
-class MockStack : public StackInterface<Elem> {
- public:
-  ...
-  MOCK_CONST_METHOD0_T(GetSize, int());
-  MOCK_METHOD1_T(Push, void(const Elem& x));
-};
-```
-
-## Specifying Calling Conventions for Mock Functions ##
-
-If your mock function doesn't use the default calling convention, you
-can specify it by appending `_WITH_CALLTYPE` to any of the macros
-described in the previous two sections and supplying the calling
-convention as the first argument to the macro. For example,
-```
-  MOCK_METHOD1_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, bool(int n));
-  MOCK_CONST_METHOD2_WITH_CALLTYPE(STDMETHODCALLTYPE, Bar, int(double x, double y));
-```
-where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
-
-# Using Mocks in Tests #
-
-The typical flow is:
-  1. Import the Google Mock names you need to use. All Google Mock names are in the `testing` namespace unless they are macros or otherwise noted.
-  1. Create the mock objects.
-  1. Optionally, set the default actions of the mock objects.
-  1. Set your expectations on the mock objects (How will they be called? What wil they do?).
-  1. Exercise code that uses the mock objects; if necessary, check the result using [Google Test](../../googletest/) assertions.
-  1. When a mock objects is destructed, Google Mock automatically verifies that all expectations on it have been satisfied.
-
-Here is an example:
-```
-using ::testing::Return;                            // #1
-
-TEST(BarTest, DoesThis) {
-  MockFoo foo;                                    // #2
-
-  ON_CALL(foo, GetSize())                         // #3
-      .WillByDefault(Return(1));
-  // ... other default actions ...
-
-  EXPECT_CALL(foo, Describe(5))                   // #4
-      .Times(3)
-      .WillRepeatedly(Return("Category 5"));
-  // ... other expectations ...
-
-  EXPECT_EQ("good", MyProductionFunction(&foo));  // #5
-}                                                 // #6
-```
-
-# Setting Default Actions #
-
-Google Mock has a **built-in default action** for any function that
-returns `void`, `bool`, a numeric value, or a pointer.
-
-To customize the default action for functions with return type `T` globally:
-```
-using ::testing::DefaultValue;
-
-// Sets the default value to be returned. T must be CopyConstructible.
-DefaultValue<T>::Set(value);
-// Sets a factory. Will be invoked on demand. T must be MoveConstructible.
-//   T MakeT();
-DefaultValue<T>::SetFactory(&MakeT);
-// ... use the mocks ...
-// Resets the default value.
-DefaultValue<T>::Clear();
-```
-
-To customize the default action for a particular method, use `ON_CALL()`:
-```
-ON_CALL(mock_object, method(matchers))
-    .With(multi_argument_matcher)  ?
-    .WillByDefault(action);
-```
-
-# Setting Expectations #
-
-`EXPECT_CALL()` sets **expectations** on a mock method (How will it be
-called? What will it do?):
-```
-EXPECT_CALL(mock_object, method(matchers))
-    .With(multi_argument_matcher)  ?
-    .Times(cardinality)            ?
-    .InSequence(sequences)         *
-    .After(expectations)           *
-    .WillOnce(action)              *
-    .WillRepeatedly(action)        ?
-    .RetiresOnSaturation();        ?
-```
-
-If `Times()` is omitted, the cardinality is assumed to be:
-
-  * `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
-  * `Times(n)` when there are `n WillOnce()`s but no `WillRepeatedly()`, where `n` >= 1; or
-  * `Times(AtLeast(n))` when there are `n WillOnce()`s and a `WillRepeatedly()`, where `n` >= 0.
-
-A method with no `EXPECT_CALL()` is free to be invoked _any number of times_, and the default action will be taken each time.
-
-# Matchers #
-
-A **matcher** matches a _single_ argument.  You can use it inside
-`ON_CALL()` or `EXPECT_CALL()`, or use it to validate a value
-directly:
-
-| `EXPECT_THAT(value, matcher)` | Asserts that `value` matches `matcher`. |
-|:------------------------------|:----------------------------------------|
-| `ASSERT_THAT(value, matcher)` | The same as `EXPECT_THAT(value, matcher)`, except that it generates a **fatal** failure. |
-
-Built-in matchers (where `argument` is the function argument) are
-divided into several categories:
-
-## Wildcard ##
-|`_`|`argument` can be any value of the correct type.|
-|:--|:-----------------------------------------------|
-|`A<type>()` or `An<type>()`|`argument` can be any value of type `type`.     |
-
-## Generic Comparison ##
-
-|`Eq(value)` or `value`|`argument == value`|
-|:---------------------|:------------------|
-|`Ge(value)`           |`argument >= value`|
-|`Gt(value)`           |`argument > value` |
-|`Le(value)`           |`argument <= value`|
-|`Lt(value)`           |`argument < value` |
-|`Ne(value)`           |`argument != value`|
-|`IsNull()`            |`argument` is a `NULL` pointer (raw or smart).|
-|`NotNull()`           |`argument` is a non-null pointer (raw or smart).|
-|`VariantWith<T>(m)`   |`argument` is `variant<>` that holds the alternative of
-type T with a value matching `m`.|
-|`Ref(variable)`       |`argument` is a reference to `variable`.|
-|`TypedEq<type>(value)`|`argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded.|
-
-Except `Ref()`, these matchers make a _copy_ of `value` in case it's
-modified or destructed later. If the compiler complains that `value`
-doesn't have a public copy constructor, try wrap it in `ByRef()`,
-e.g. `Eq(ByRef(non_copyable_value))`. If you do that, make sure
-`non_copyable_value` is not changed afterwards, or the meaning of your
-matcher will be changed.
-
-## Floating-Point Matchers ##
-
-|`DoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal.|
-|:-------------------|:----------------------------------------------------------------------------------------------|
-|`FloatEq(a_float)`  |`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal.  |
-|`NanSensitiveDoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal.  |
-|`NanSensitiveFloatEq(a_float)`|`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal.    |
-
-The above matchers use ULP-based comparison (the same as used in
-[Google Test](../../googletest/)). They
-automatically pick a reasonable error bound based on the absolute
-value of the expected value.  `DoubleEq()` and `FloatEq()` conform to
-the IEEE standard, which requires comparing two NaNs for equality to
-return false. The `NanSensitive*` version instead treats two NaNs as
-equal, which is often what a user wants.
-
-|`DoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal.|
-|:------------------------------------|:--------------------------------------------------------------------------------------------------------------------|
-|`FloatNear(a_float, max_abs_error)`  |`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal.  |
-|`NanSensitiveDoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal.  |
-|`NanSensitiveFloatNear(a_float, max_abs_error)`|`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal.    |
-
-## String Matchers ##
-
-The `argument` can be either a C string or a C++ string object:
-
-|`ContainsRegex(string)`|`argument` matches the given regular expression.|
-|:----------------------|:-----------------------------------------------|
-|`EndsWith(suffix)`     |`argument` ends with string `suffix`.           |
-|`HasSubstr(string)`    |`argument` contains `string` as a sub-string.   |
-|`MatchesRegex(string)` |`argument` matches the given regular expression with the match starting at the first character and ending at the last character.|
-|`StartsWith(prefix)`   |`argument` starts with string `prefix`.         |
-|`StrCaseEq(string)`    |`argument` is equal to `string`, ignoring case. |
-|`StrCaseNe(string)`    |`argument` is not equal to `string`, ignoring case.|
-|`StrEq(string)`        |`argument` is equal to `string`.                |
-|`StrNe(string)`        |`argument` is not equal to `string`.            |
-
-`ContainsRegex()` and `MatchesRegex()` use the regular expression
-syntax defined
-[here](../../googletest/docs/AdvancedGuide.md#regular-expression-syntax).
-`StrCaseEq()`, `StrCaseNe()`, `StrEq()`, and `StrNe()` work for wide
-strings as well.
-
-## Container Matchers ##
-
-Most STL-style containers support `==`, so you can use
-`Eq(expected_container)` or simply `expected_container` to match a
-container exactly.   If you want to write the elements in-line,
-match them more flexibly, or get more informative messages, you can use:
-
-| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
-|:-------------------------|:---------------------------------------------------------------------------------------------------------------------------------|
-| `Contains(e)`            | `argument` contains an element that matches `e`, which can be either a value or a matcher.                                       |
-| `Each(e)`                | `argument` is a container where _every_ element matches `e`, which can be either a value or a matcher.                           |
-| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the i-th element matches `ei`, which can be a value or a matcher. 0 to 10 arguments are allowed. |
-| `ElementsAreArray({ e0, e1, ..., en })`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. |
-| `IsEmpty()`              | `argument` is an empty container (`container.empty()`).                                                                          |
-| `Pointwise(m, container)` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
-| `SizeIs(m)`              | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`.                                           |
-| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under some permutation each element matches an `ei` (for a different `i`), which can be a value or a matcher. 0 to 10 arguments are allowed. |
-| `UnorderedElementsAreArray({ e0, e1, ..., en })`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. |
-| `WhenSorted(m)`          | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements `1`, `2`, and `3`, ignoring order. |
-| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater<int>(), ElementsAre(3, 2, 1))`. |
-
-Notes:
-
-  * These matchers can also match:
-    1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`), and
-    1. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer, int len)` -- see [Multi-argument Matchers](#Multiargument_Matchers.md)).
-  * The array being matched may be multi-dimensional (i.e. its elements can be arrays).
-  * `m` in `Pointwise(m, ...)` should be a matcher for `::testing::tuple<T, U>` where `T` and `U` are the element type of the actual container and the expected container, respectively. For example, to compare two `Foo` containers where `Foo` doesn't support `operator==` but has an `Equals()` method, one might write:
-
-```
-using ::testing::get;
-MATCHER(FooEq, "") {
-  return get<0>(arg).Equals(get<1>(arg));
-}
-...
-EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
-```
-
-## Member Matchers ##
-
-|`Field(&class::field, m)`|`argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
-|:------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------|
-|`Key(e)`                 |`argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`.|
-|`Pair(m1, m2)`           |`argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`.                                                |
-|`Property(&class::property, m)`|`argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
-
-## Matching the Result of a Function or Functor ##
-
-|`ResultOf(f, m)`|`f(argument)` matches matcher `m`, where `f` is a function or functor.|
-|:---------------|:---------------------------------------------------------------------|
-
-## Pointer Matchers ##
-
-|`Pointee(m)`|`argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`.|
-|:-----------|:-----------------------------------------------------------------------------------------------|
-|`WhenDynamicCastTo<T>(m)`| when `argument` is passed through `dynamic_cast<T>()`, it matches matcher `m`.                 |
-
-## Multiargument Matchers ##
-
-Technically, all matchers match a _single_ value. A "multi-argument"
-matcher is just one that matches a _tuple_. The following matchers can
-be used to match a tuple `(x, y)`:
-
-|`Eq()`|`x == y`|
-|:-----|:-------|
-|`Ge()`|`x >= y`|
-|`Gt()`|`x > y` |
-|`Le()`|`x <= y`|
-|`Lt()`|`x < y` |
-|`Ne()`|`x != y`|
-
-You can use the following selectors to pick a subset of the arguments
-(or reorder them) to participate in the matching:
-
-|`AllArgs(m)`|Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`.|
-|:-----------|:-------------------------------------------------------------------|
-|`Args<N1, N2, ..., Nk>(m)`|The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`.|
-
-## Composite Matchers ##
-
-You can make a matcher from one or more other matchers:
-
-|`AllOf(m1, m2, ..., mn)`|`argument` matches all of the matchers `m1` to `mn`.|
-|:-----------------------|:---------------------------------------------------|
-|`AnyOf(m1, m2, ..., mn)`|`argument` matches at least one of the matchers `m1` to `mn`.|
-|`Not(m)`                |`argument` doesn't match matcher `m`.               |
-
-## Adapters for Matchers ##
-
-|`MatcherCast<T>(m)`|casts matcher `m` to type `Matcher<T>`.|
-|:------------------|:--------------------------------------|
-|`SafeMatcherCast<T>(m)`| [safely casts](CookBook.md#casting-matchers) matcher `m` to type `Matcher<T>`. |
-|`Truly(predicate)` |`predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor.|
-
-## Matchers as Predicates ##
-
-|`Matches(m)(value)`|evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor.|
-|:------------------|:---------------------------------------------------------------------------------------------|
-|`ExplainMatchResult(m, value, result_listener)`|evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`.       |
-|`Value(value, m)`  |evaluates to `true` if `value` matches `m`.                                                   |
-
-## Defining Matchers ##
-
-| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
-|:-------------------------------------------------|:------------------------------------------------------|
-| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a macher `IsDivisibleBy(n)` to match a number divisible by `n`. |
-| `MATCHER_P2(IsBetween, a, b, std::string(negation ? "isn't" : "is") + " between " + PrintToString(a) + " and " + PrintToString(b)) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
-
-**Notes:**
-
-  1. The `MATCHER*` macros cannot be used inside a function or class.
-  1. The matcher body must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters).
-  1. You can use `PrintToString(x)` to convert a value `x` of any type to a string.
-
-## Matchers as Test Assertions ##
-
-|`ASSERT_THAT(expression, m)`|Generates a [fatal failure](../../googletest/docs/Primer.md#assertions) if the value of `expression` doesn't match matcher `m`.|
-|:---------------------------|:----------------------------------------------------------------------------------------------------------------------------------------------|
-|`EXPECT_THAT(expression, m)`|Generates a non-fatal failure if the value of `expression` doesn't match matcher `m`.                                                          |
-
-# Actions #
-
-**Actions** specify what a mock function should do when invoked.
-
-## Returning a Value ##
-
-|`Return()`|Return from a `void` mock function.|
-|:---------|:----------------------------------|
-|`Return(value)`|Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed.|
-|`ReturnArg<N>()`|Return the `N`-th (0-based) argument.|
-|`ReturnNew<T>(a1, ..., ak)`|Return `new T(a1, ..., ak)`; a different object is created each time.|
-|`ReturnNull()`|Return a null pointer.             |
-|`ReturnPointee(ptr)`|Return the value pointed to by `ptr`.|
-|`ReturnRef(variable)`|Return a reference to `variable`.  |
-|`ReturnRefOfCopy(value)`|Return a reference to a copy of `value`; the copy lives as long as the action.|
-
-## Side Effects ##
-
-|`Assign(&variable, value)`|Assign `value` to variable.|
-|:-------------------------|:--------------------------|
-| `DeleteArg<N>()`         | Delete the `N`-th (0-based) argument, which must be a pointer. |
-| `SaveArg<N>(pointer)`    | Save the `N`-th (0-based) argument to `*pointer`. |
-| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
-| `SetArgReferee<N>(value)` |	Assign value to the variable referenced by the `N`-th (0-based) argument. |
-|`SetArgPointee<N>(value)` |Assign `value` to the variable pointed by the `N`-th (0-based) argument.|
-|`SetArgumentPointee<N>(value)`|Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0.|
-|`SetArrayArgument<N>(first, last)`|Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range.|
-|`SetErrnoAndReturn(error, value)`|Set `errno` to `error` and return `value`.|
-|`Throw(exception)`        |Throws the given exception, which can be any copyable value. Available since v1.1.0.|
-
-## Using a Function or a Functor as an Action ##
-
-|`Invoke(f)`|Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor.|
-|:----------|:-----------------------------------------------------------------------------------------------------------------|
-|`Invoke(object_pointer, &class::method)`|Invoke the {method on the object with the arguments passed to the mock function.                                  |
-|`InvokeWithoutArgs(f)`|Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments.                       |
-|`InvokeWithoutArgs(object_pointer, &class::method)`|Invoke the method on the object, which takes no arguments.                                                        |
-|`InvokeArgument<N>(arg1, arg2, ..., argk)`|Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments.|
-
-The return value of the invoked function is used as the return value
-of the action.
-
-When defining a function or functor to be used with `Invoke*()`, you can declare any unused parameters as `Unused`:
-```
-  double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
-  ...
-  EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
-```
-
-In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference, wrap it inside `ByRef()`. For example,
-```
-  InvokeArgument<2>(5, string("Hi"), ByRef(foo))
-```
-calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by value, and `foo` by reference.
-
-## Default Action ##
-
-|`DoDefault()`|Do the default action (specified by `ON_CALL()` or the built-in one).|
-|:------------|:--------------------------------------------------------------------|
-
-**Note:** due to technical reasons, `DoDefault()` cannot be used inside  a composite action - trying to do so will result in a run-time error.
-
-## Composite Actions ##
-
-|`DoAll(a1, a2, ..., an)`|Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void. |
-|:-----------------------|:-----------------------------------------------------------------------------------------------------------------------------|
-|`IgnoreResult(a)`       |Perform action `a` and ignore its result. `a` must not return void.                                                           |
-|`WithArg<N>(a)`         |Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it.                                         |
-|`WithArgs<N1, N2, ..., Nk>(a)`|Pass the selected (0-based) arguments of the mock function to action `a` and perform it.                                      |
-|`WithoutArgs(a)`        |Perform action `a` without any arguments.                                                                                     |
-
-## Defining Actions ##
-
-| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
-|:--------------------------------------|:---------------------------------------------------------------------------------------|
-| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
-| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`.   |
-
-The `ACTION*` macros cannot be used inside a function or class.
-
-# Cardinalities #
-
-These are used in `Times()` to specify how many times a mock function will be called:
-
-|`AnyNumber()`|The function can be called any number of times.|
-|:------------|:----------------------------------------------|
-|`AtLeast(n)` |The call is expected at least `n` times.       |
-|`AtMost(n)`  |The call is expected at most `n` times.        |
-|`Between(m, n)`|The call is expected between `m` and `n` (inclusive) times.|
-|`Exactly(n) or n`|The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0.|
-
-# Expectation Order #
-
-By default, the expectations can be matched in _any_ order.  If some
-or all expectations must be matched in a given order, there are two
-ways to specify it.  They can be used either independently or
-together.
-
-## The After Clause ##
-
-```
-using ::testing::Expectation;
-...
-Expectation init_x = EXPECT_CALL(foo, InitX());
-Expectation init_y = EXPECT_CALL(foo, InitY());
-EXPECT_CALL(foo, Bar())
-    .After(init_x, init_y);
-```
-says that `Bar()` can be called only after both `InitX()` and
-`InitY()` have been called.
-
-If you don't know how many pre-requisites an expectation has when you
-write it, you can use an `ExpectationSet` to collect them:
-
-```
-using ::testing::ExpectationSet;
-...
-ExpectationSet all_inits;
-for (int i = 0; i < element_count; i++) {
-  all_inits += EXPECT_CALL(foo, InitElement(i));
-}
-EXPECT_CALL(foo, Bar())
-    .After(all_inits);
-```
-says that `Bar()` can be called only after all elements have been
-initialized (but we don't care about which elements get initialized
-before the others).
-
-Modifying an `ExpectationSet` after using it in an `.After()` doesn't
-affect the meaning of the `.After()`.
-
-## Sequences ##
-
-When you have a long chain of sequential expectations, it's easier to
-specify the order using **sequences**, which don't require you to given
-each expectation in the chain a different name.  <i>All expected<br>
-calls</i> in the same sequence must occur in the order they are
-specified.
-
-```
-using ::testing::Sequence;
-Sequence s1, s2;
-...
-EXPECT_CALL(foo, Reset())
-    .InSequence(s1, s2)
-    .WillOnce(Return(true));
-EXPECT_CALL(foo, GetSize())
-    .InSequence(s1)
-    .WillOnce(Return(1));
-EXPECT_CALL(foo, Describe(A<const char*>()))
-    .InSequence(s2)
-    .WillOnce(Return("dummy"));
-```
-says that `Reset()` must be called before _both_ `GetSize()` _and_
-`Describe()`, and the latter two can occur in any order.
-
-To put many expectations in a sequence conveniently:
-```
-using ::testing::InSequence;
-{
-  InSequence dummy;
-
-  EXPECT_CALL(...)...;
-  EXPECT_CALL(...)...;
-  ...
-  EXPECT_CALL(...)...;
-}
-```
-says that all expected calls in the scope of `dummy` must occur in
-strict order. The name `dummy` is irrelevant.)
-
-# Verifying and Resetting a Mock #
-
-Google Mock will verify the expectations on a mock object when it is destructed, or you can do it earlier:
-```
-using ::testing::Mock;
-...
-// Verifies and removes the expectations on mock_obj;
-// returns true iff successful.
-Mock::VerifyAndClearExpectations(&mock_obj);
-...
-// Verifies and removes the expectations on mock_obj;
-// also removes the default actions set by ON_CALL();
-// returns true iff successful.
-Mock::VerifyAndClear(&mock_obj);
-```
-
-You can also tell Google Mock that a mock object can be leaked and doesn't
-need to be verified:
-```
-Mock::AllowLeak(&mock_obj);
-```
-
-# Mock Classes #
-
-Google Mock defines a convenient mock class template
-```
-class MockFunction<R(A1, ..., An)> {
- public:
-  MOCK_METHODn(Call, R(A1, ..., An));
-};
-```
-See this [recipe](CookBook.md#using-check-points) for one application of it.
