 You can create ``.clang-format-ignore`` files to make ``clang-format`` ignore
 certain files. A ``.clang-format-ignore`` file consists of patterns of file path
 names. It has the following format:
-- A blank line is skipped.
-- Leading and trailing spaces of a line are trimmed.
-- A line starting with a hash (``#``) is a comment.
-- A non-comment line is a single pattern.
-- The slash (``/``) is used as the directory separator.
-- A pattern is relative to the directory of the ``.clang-format-ignore`` file
-(or the root directory if the pattern starts with a slash).
-- Patterns follow the rules specified in POSIX 2.13.1, 2.13.2, and Rule 1 of
-2.13.3.
-- A pattern is negated if it starts with a bang (``!``).

 To match all files in a directory, use e.g. ``foo/bar/*``. To match all files in
 the directory of the ``.clang-format-ignore`` file, use ``*``.
