 # 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 # the version will be out-of-date.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.
