{#
|
||||
Those macros deal with introduction and navigation for series pages.
|
||||
Using macros have been prefered over partial inclusion or inline code to make sure series_ordered_pages is forced to be used.
|
||||
A section's pages natural order is invalid in case of reversed pagination which would lead to invalid series' pages order.
|
||||
To prevent this, pages are ordered correctly in a separate variable which must be used instead of the series section pages.

{#

Computes the introduction of a series's page.
|

|
||||
Parameters:
|
||||
- `page`: The page object being part of the series.
|
||||
- `series_section`: The series' section the page belongs to.
|
||||
- `series_ordered_pages`: The series' pages properly ordered (see at the top of this file for an explanation).
|
||||
- `language_strings`: A dictionary containing the translation strings.
