  22  * Note: The index may be checked for .gitignore files that are
  23  * CE_SKIP_WORKTREE marked. If you want to exclude files, make sure you have
  24  * loaded the index first.
  25  *
  26  * - Prepare `struct dir_struct dir` using `dir_init()` function.
  27  *
  28  * - To add single exclude pattern, call `add_pattern_list()` and then
  29  *   `add_pattern()`.
  30  *
  31  * - To add patterns from a file (e.g. `.git/info/exclude`), call
  32  *   `add_patterns_from_file()` , and/or set `dir.exclude_per_dir`.
  33  *
  34  * - A short-hand function `setup_standard_excludes()` can be used to set
  35  *   up the standard set of exclude settings, instead of manually calling
  36  *   the add_pattern*() family of functions.
  37  *
  38  * - Call `fill_directory()`.
  39  *
  40  * - Use `dir.entries[]` and `dir.ignored[]`.
  41  *
  42  * - Call `dir_clear()` when the contained elements are no longer in use.
