 +# Meson build system
 +# ==================
 +#
 +# The Meson build system is an alternative to our Makefile that you can use to
 +# build, test and install Git. Using Meson results in a couple of benefits:
 +#
 +#  - Out-of-tree builds.
 +#  - Better integration into IDEs.
 +#  - Easy-to-use autoconfiguration of available features on your system.
 +#
 +# To use Meson from the command line you need to have both Meson and Ninja
 +# installed. Alternatively, if you do not have Python available on your system,
 +# you can also use Muon instead of Meson and Samurai instead of Ninja, both of
 +# which are drop-ins replacement that only depend on C.
 +#
 +# Basic usage
 +# ===========
 +#
 +# In the most trivial case, you can configure, build and install Git like this:
 +#
 +#  1. Set up the build directory. This only needs to happen once per build
 +#     directory you want to have. You can also configure multiple different
 +#     build directories with different configurations.
 +#
 +#      $ meson setup build/
 +#
 +#     The build directory gets ignored by Git automatically as Meson will write
 +#     a ".gitignore" file into it. From hereon, we will assume that you execute
 +#     commands inside this build directory.
 +#
 +# 2. Compile Git. You can either use Meson, Ninja or Samurai to do this, so all
 +#    of the following invocations are equivalent:
 +#
 +#      $ meson compile
 +#      $ ninja
 +#      $ samu
 +#
 +#   The different invocations should ultimately not make much of a difference.
 +#   Using Meson also works with other generators though, like when the build
 +#   directory has been set up for use with Microsoft Visual Studio.
 +#
 +#   Ninja and Samurai use multiple jobs by default, scaling with the number of
 +#   processor cores available. You can pass the `-jN` flag to change this.
 +#
 +#   Meson automatically picks up ccache and sccache when these are installed
 +#   when setting up the build directory. You can override this behaviour when
 +#   setting up the build directory by setting the `CC` environment variable to
 +#   your desired compiler.
 +#
 +# 3. Execute tests. Again, you can either use Meson, Ninja or Samurai to do this:
 +#
 +#      $ meson test
 +#      $ ninja test
 +#      $ samu test
 +#
 +#   It is recommended to use Meson in this case though as it also provides you
 +#   additional features that the other build systems don't have available.
 +#   You can e.g. pass additional arguments to the test executables or run
 +#   individual tests:
 +#
 +#      # Execute the t0000-basic integration test and t-reftable-stack unit test.
 +#      $ meson test t0000-basic t-reftable-stack
 +#
 +#      # Execute all reftable unit tests.
 +#      $ meson test t-reftable-*
 +#
 +#      # Execute all tests and stop with the first failure.
 +#      $ meson test --maxfail 1
 +#
 +#      # Execute single test interactively such that features like `debug ()` work.
 +#      $ meson test -i --test-args='-ix' t1400-update-ref
 +#
 +#   Test execution is parallelized by default and scales with the number of
 +#   processor cores available. You can change the number of processes by passing
 +#   the `-jN` flag to `meson test`.
 +#
 +# 4. Install the Git distribution. Again, this can be done via Meson, Ninja or
 +#    Samurai:
 +#
 +#      $ meson install
 +#      $ ninja install
 +#      $ samu install
 +#
 +#    The prefix into which Git shall be installed is defined when setting up
 +#    the build directory. More on that in the "Configuration" section.
 +#
 +# Meson supports multiple backends. The default backend generates Ninja build
 +# instructions, but it also supports the generation of Microsoft Visual
 +# Studio solutions as well as Xcode projects by passing the `--backend` option
 +# to `meson setup`. IDEs like Eclipse and Visual Studio Code provide plugins to
 +# import Meson files directly.
 +#
 +# Configuration
 +# =============
 +#
 +# The exact configuration of Git is determined when setting up the build
 +# directory via `meson setup`. Unless told otherwise, Meson will automatically
 +# detect the availability of various bits and pieces. There are two different
 +# kinds of options that can be used to further tweak the build:
 +#
 +#   - Built-in options provided by Meson.
 +#
 +#   - Options defined by the project in the "meson_options.txt" file.
 +#
 +# Both kinds of options can be inspected by running `meson configure` in the
 +# build directory, which will give you a list of the current value for all
 +# options.
 +#
 +# Options can be configured either when setting up the build directory or can
 +# be changed in preexisting build directories:
 +#
 +#      # Set up a new build directory with optimized settings that will be
 +#      # installed into an alternative prefix.
 +#      $ meson setup --buildtype release --optimization 3 --strip --prefix=/home/$USER build
 +#
 +#      # Set up a new build directory with a higher warning level. Level 2 is
 +#      # mostly equivalent to setting DEVELOPER=1, level 3 and "everything"
 +#      # will enable even more warnings.
 +#      $ meson setup -Dwarning_level=2 build
 +#
 +#      # Set up a new build directory with 'address' and 'undefined' sanitizers
 +#      # using Clang.
 +#      $ CC=clang meson setup -Db_sanitize=address,undefined build
 +#
 +#      # Disable tests in a preexisting build directory.
 +#      $ meson configure -Dtests=false
 +#
 +#      # Disable features based on Python
 +#      $ meson configure -Dpython=disabled
 +#
 +# Options have a type like booleans, choices, strings or features. Features are
 +# somewhat special as they can have one of three values: enabled, disabled or
 +# auto. While the first two values are self-explanatory, "auto" will enable or
 +# disable the feature based on the availability of prerequisites to support it.
 +# Python-based features for example will be enabled automatically when a Python
 +# interpreter could be found. The default value of such features can be changed
 +# via `meson setup --auto-features={enabled,disabled,auto}`, which will set the
 +# value of all features with a value of "auto" to the provided one by default.
 +#
 +# It is also possible to store a set of configuration options in machine files.
 +# This can be useful in case you regularly want to reuse the same set of options:
 +#
 +#   [binaries]
 +#   c = ['clang']
 +#   ar = ['ar']
 +#
 +#   [project options]
 +#   gettext = 'disabled'
 +#   default_editor = 'vim'
 +#
 +#   [built-in options]
 +#   b_lto = true
 +#   b_sanitize = 'address,undefined'
 +#
 +# These machine files can be passed to `meson setup` via the `--native-file`
 +# option.
 +#
 +# Subproject wrappers
 +# ===================
 +#
 +# Subproject wrappers are a feature provided by Meson that allows the automatic
 +# fallback to a "wrapped" dependency in case the dependency is not provided by
 +# the system. For example if the system is lacking curl, then Meson will use
 +# "subprojects/curl.wrap" to set up curl as a subproject and compile and link
 +# the dependency into Git itself. This is especially helpful on systems like
 +# Windows, where you typically don't have such dependencies installed.
 +#
 +# The use of subproject wrappers can be disabled by executing `meson setup`
 +# with the `--wrap-mode nofallback` option.
