-# This script removes the platform-specific clang_format binaries from
-# third_party/clang_format/bin* now that the binaries have been moved to
-# src/buildtools. Keeping the old ones around will be pretty confusing since
-# the version will be out-of-date.
-#
-# This script assumes it is located in third_party/clang_format/bin and locates
-# the binaries relative to itself.
-#
-# TODO(jochen) remove this script when people have likely been updated.
-# End of July 2014 would be good.
