#
#  There are some known cases that this doesn't produce the desired
#  style (i.e Preprocessor Directives are over-indented and not
#  auto-commented). As a result, this is meant to be a utility to make
#  formatting easier, not a definitive standard.
#
#  To format the current git diff inplace (-i) the follow command can
#  be used:
#  $> git diff -U0 --no-color HEAD^ | clang-format-diff -i -p1
#
#  To just view the diff clang-format would generate:
#  $> git diff -U0 --no-color HEAD^ | clang-format-diff -p1
#
#  NB: clang-format-diff, along with other clang-format related tools,
#      can be found at: /path/to/llvm-project/clang/tools/clang-format/
#
#
#  Based on autogenerated format from:
#  $> clang-format --style=GNU -dump-config
