+## This config file is only relevant for clang-format version 8.0.0
+##
+## Examples of each format style can be found on the in the clang-format documentation
+## See: https://clang.llvm.org/docs/ClangFormatStyleOptions.html for details of each option
+##
+## The clang-format binaries can be downloaded as part of the clang binary distributions
+## from http://releases.llvm.org/download.html
+##
+## Use the script Utilities/Maintenance/clang-format.bash to faciliate
+## maintaining a consistent code style.

+## EXAMPLE apply code style enforcement before commit:
+#     Utilities/Maintenance/clang-format.bash --clang ${PATH_TO_CLANG_FORMAT_8.0.0} --modified
+## EXAMPLE apply code style enforcement after commit:
+#     Utilities/Maintenance/clang-format.bash --clang ${PATH_TO_CLANG_FORMAT_8.0.0} --last

+# maintain with code beautification tools.  Not indenting braces is more common among
