--[==[ This module is a Lua implementation of the old {{Portal}} template. As of February 2019 it is used on nearly 7,900,000 articles.
-- Please take care when updating it! It outputs two functions: p.portal, which generates a list of portals, and p.image, which
-- produces the image name for an individual portal.

-- The portal image data is kept in submodules of [[Module:Portal/images]], listed below:
-- [[Module:Portal/images/a]]		- for portal names beginning with "A".
-- [[Module:Portal/images/b]]		- for portal names beginning with "B".
-- [[Module:Portal/images/c]]		- for portal names beginning with "C".
-- [[Module:Portal/images/d]]		- for portal names beginning with "D".
-- [[Module:Portal/images/e]]		- for portal names beginning with "E".
-- [[Module:Portal/images/f]]		- for portal names beginning with "F".
-- [[Module:Portal/images/g]]		- for portal names beginning with "G".
-- [[Module:Portal/images/h]]		- for portal names beginning with "H".
-- [[Module:Portal/images/i]]		- for portal names beginning with "I".
-- [[Module:Portal/images/j]]		- for portal names beginning with "J".
-- [[Module:Portal/images/k]]		- for portal names beginning with "K".
-- [[Module:Portal/images/l]]		- for portal names beginning with "L".
-- [[Module:Portal/images/m]]		- for portal names beginning with "M".
-- [[Module:Portal/images/n]]		- for portal names beginning with "N".
-- [[Module:Portal/images/o]]		- for portal names beginning with "O".
-- [[Module:Portal/images/p]]		- for portal names beginning with "P".
-- [[Module:Portal/images/q]]		- for portal names beginning with "Q".
-- [[Module:Portal/images/r]]		- for portal names beginning with "R".
-- [[Module:Portal/images/s]]		- for portal names beginning with "S".
-- [[Module:Portal/images/t]]		- for portal names beginning with "T".
-- [[Module:Portal/images/u]]		- for portal names beginning with "U".
-- [[Module:Portal/images/v]]		- for portal names beginning with "V".
-- [[Module:Portal/images/w]]		- for portal names beginning with "W".
-- [[Module:Portal/images/x]]		- for portal names beginning with "X".
-- [[Module:Portal/images/y]]		- for portal names beginning with "Y".
-- [[Module:Portal/images/z]]		- for portal names beginning with "Z".
-- [[Module:Portal/images/other]]	- for portal names beginning with any other letters. This includes numbers,
-- 									  letters with diacritics, and letters in non-Latin alphabets.
-- [[Module:Portal/images/aliases]]	- for adding aliases for existing portal names. Use this page for variations
-- 									  in spelling and diacritics, etc., no matter what letter the portal begins with.
--
-- The images data pages are separated by the first letter to reduce server load when images are added, changed, or removed.
-- Previously all the images were on one data page at [[Module:Portal/images]], but this had the disadvantage that all
-- 5,000,000 pages using this module needed to be refreshed every time an image was added or removed.
