+# This file is meant to be included to set clang-specific compiler flags.
+# To use this the following variable can be defined:
+# clang_warning_flags: list: Compiler flags to pass to clang.
+# clang_warning_flags_unset: list: Compiler flags to not pass to clang.
+#
+# Only use this in third-party code. In chromium_code, fix your code to not
+# warn instead!
+#
+# Note that the gypi file is included in target_defaults, so it does not need
+# to be explicitly included.
+#
+# Warning flags set by this will be used on all platforms. If you want to set
+# warning flags on only some platforms, you have to do so manually.

+# To use this, create a gyp target with the following form:
+# {
+# 'target_name': 'my_target',
+# 'variables': {
+# 'clang_warning_flags': ['-Wno-awesome-warning'],
+# 'clang_warning_flags_unset': ['-Wpreviously-set-flag'],
