# We use `glob()` instead of `find_exts()` in the tools directory, because:
#   * On Windows, `os.walk()` (called by `find_exts()`) follows symlinks.
#   * The tools directory contains a symlink 'clang', pointing at the directory
#     'third_party/v8/tools/clang', which contains many .py files.
#   * These third party python files shouldn't be formatted.
#   * The tools directory has no subdirectories, so `glob()` is sufficient.
