-# Configuration of clang-format
-# =============================
-#
-# Tested to work with versions: 8 to 11.
-
-# This causes parameters on continuations to align to the opening brace.
-#
-#   like_this_long_name(parameter_one,
-#                       parameter_two,
-#                       parameter_three);
-#
-AlignAfterOpenBracket: 'Align'
-
-# Disallow short functions on one line; break them up.
-AllowShortBlocksOnASingleLine: false
-
-# These two settings trigger stacking of parameters in most cases; this is
-# easier to read and also makes diffs easier to read (since an added or removed
-# parameter is obvious). For example, function calls will look like this:
-#
-#   like_this_long_name(parameter_one,
-#                       parameter_two,
-#                       parameter_three,
-#                       parameter_four,
-#                       parameter_five,
-#                       parameter_six);

-Blender Convenience Targets
-   Provided for building Blender, (multiple at once can be used).
-
-   * debug:         Build a debug binary.
-   * full:          Enable all supported dependencies & options.
-   * lite:          Disable non essential features for a smaller binary and faster build.
-   * release:       Complete build with all options enabled including CUDA and Optix, matching the releases on blender.org
-   * headless:      Build without an interface (renderfarm or server automation).
-   * cycles:        Build Cycles standalone only, without Blender.
-   * bpy:           Build as a python module which can be loaded from python directly.
-   * developer:     Enable faster builds, error checking and tests, recommended for developers.
-   * ninja:         Use ninja build tool for faster builds.
-   * ccache:        Use ccache for faster rebuilds.
-
-   Note: passing the argument 'BUILD_DIR=path' when calling make will override the default build dir.
-   Note: passing the argument 'BUILD_CMAKE_ARGS=args' lets you add cmake arguments.
-
-Other Convenience Targets
-   Provided for other building operations.
-
-   * config:        Run cmake configuration tool to set build options.
-   * deps:          Build library dependencies (intended only for platform maintainers).
-
-                    The existance of locally build dependancies overrides the pre-built dependencies from subversion.
-                    These must be manually removed from '../lib/' to go back to using the pre-compiled libraries.
-
-Project Files
-   Generate project files for development environments.
-
-   * project_qtcreator:     QtCreator Project Files.
-   * project_netbeans:      NetBeans Project Files.
-   * project_eclipse:       Eclipse CDT4 Project Files.
-
-Package Targets
-
-   * package_debian:    Build a debian package.
-   * package_pacman:    Build an arch linux pacman package.
-   * package_archive:	Build an archive package.
-
-Testing Targets
-   Not associated with building Blender.
-
-   * test:
-     Run automated tests with ctest.
-   * test_cmake:
-     Runs our own cmake file checker
-     which detects errors in the cmake file list definitions
-   * test_pep8:
-     Checks all python script are pep8
-     which are tagged to use the stricter formatting
-   * test_deprecated:
-     Checks for deprecation tags in our code which may need to be removed
-
-Static Source Code Checking
-   Not associated with building Blender.
-
-   * check_cppcheck:        Run blender source through cppcheck (C & C++).
-   * check_clang_array:     Run blender source through clang array checking script (C & C++).
-   * check_splint:          Run blenders source through splint (C only).
-   * check_sparse:          Run blenders source through sparse (C only).
-   * check_smatch:          Run blenders source through smatch (C only).
-   * check_descriptions:    Check for duplicate/invalid descriptions.
-
-Spell Checkers
-   This runs the spell checker from the developer tools repositor.
-
-   * check_spelling_c:      Check for spelling errors (C/C++ only),
-   * check_spelling_osl:    Check for spelling errors (OSL only).
-   * check_spelling_py:     Check for spelling errors (Python only).
-
-   Note: an additional word-list is maintained at: 'source/tools/check_source/check_spelling_c_config.py'
