-/**
- * Calling sequence
- * ----------------
- *
- * Note: The index may be checked for .gitignore files that are
- * CE_SKIP_WORKTREE marked. If you want to exclude files, make sure you have
- * loaded the index first.
- *
- * - Prepare `struct dir_struct dir` using `dir_init()` function.
- *
- * - To add single exclude pattern, call `add_pattern_list()` and then
- *   `add_pattern()`.
- *
- * - To add patterns from a file (e.g. `.git/info/exclude`), call
- *   `add_patterns_from_file()` , and/or set `dir.exclude_per_dir`.
- *
- * - A short-hand function `setup_standard_excludes()` can be used to set
- *   up the standard set of exclude settings, instead of manually calling
- *   the add_pattern*() family of functions.
- *
- * - Call `fill_directory()`.
- *
- * - Use `dir.entries[]` and `dir.ignored[]`.
- *
- * - Call `dir_clear()` when the contained elements are no longer in use.
