+Querying All Attributes
+-----------------------
+
+To get the values of all attributes associated with a file:
+
+* Call `git_all_attrs()`, which returns an array of `git_attr_check`
+  structures.
+
+* Iterate over the `git_attr_check` array to examine the attribute
+  names and values.  The name of the attribute described by a
+  `git_attr_check` object can be retrieved via
+  `git_attr_name(check[i].attr)`.  (Please note that no items will be
+  returned for unset attributes, so `ATTR_UNSET()` will return false
+  for all returned `git_array_check` objects.)
+
+* Free the `git_array_check` array.
