+        The return value is a tuple of ``(content, collapse)``, where *collapse*
+        is a boolean that determines if sub-entries should start collapsed (for
+        output formats that support collapsing sub-entries).
+
+        *content* is a sequence of ``(letter, entries)`` tuples, where *letter*
+        is the "heading" for the given *entries*, usually the starting letter.
+
+        *entries* is a sequence of single entries, where a single entry is a
+        sequence ``[name, subtype, docname, anchor, extra, qualifier, descr]``.
+        The items in this sequence have the following meaning:
+
+        - `name` -- the name of the index entry to be displayed
+        - `subtype` -- sub-entry related type:

+        - `extra` -- extra info for the entry
+        - `qualifier` -- qualifier for the description
+        - `descr` -- description for the entry
+
+        Qualifier and description are not rendered e.g. in LaTeX output.
