--[==[ This module is a Lua implementation of the old {{Portal}} template. As of August 2013 it is used on nearly 5,000,000 articles.
-- Please take care when updating it! It outputs two functions: p.portal, which generates a table 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/آ]] - for portal names beginning with "آ".
-- [[Module:Portal/images/ا]] - for portal names beginning with "ا".
-- [[Module:Portal/images/ب]] - for portal names beginning with "ب".
-- [[Module:Portal/images/پ]] - for portal names beginning with "پ".
-- [[Module:Portal/images/ت]] - for portal names beginning with "ت".
-- [[Module:Portal/images/ث]] - for portal names beginning with "ث".
-- [[Module:Portal/images/ج]] - for portal names beginning with "ج".
-- [[Module:Portal/images/چ]] - for portal names beginning with "چ".
-- [[Module:Portal/images/ح]] - for portal names beginning with "ح".
-- [[Module:Portal/images/خ]] - for portal names beginning with "خ".
-- [[Module:Portal/images/د]] - for portal names beginning with "د".
-- [[Module:Portal/images/ذ]] - for portal names beginning with "ذ".
-- [[Module:Portal/images/ر]] - for portal names beginning with "ر".
-- [[Module:Portal/images/ز]] - for portal names beginning with "ز".
-- [[Module:Portal/images/ژ]] - for portal names beginning with "ژ".
-- [[Module:Portal/images/س]] - for portal names beginning with "س".
-- [[Module:Portal/images/ش]] - for portal names beginning with "ش".
-- [[Module:Portal/images/ص]] - for portal names beginning with "ص".
-- [[Module:Portal/images/ض]] - for portal names beginning with "ض".
-- [[Module:Portal/images/ط]] - for portal names beginning with "ط".
-- [[Module:Portal/images/ظ]] - for portal names beginning with "ظ".
-- [[Module:Portal/images/ع]] - for portal names beginning with "ع".
-- [[Module:Portal/images/غ]] - for portal names beginning with "غ".
-- [[Module:Portal/images/ف]] - for portal names beginning with "ف".
-- [[Module:Portal/images/ق]] - for portal names beginning with "ق".
-- [[Module:Portal/images/ک]] - for portal names beginning with "ک".
-- [[Module:Portal/images/گ]] - for portal names beginning with "گ".
-- [[Module:Portal/images/ل]] - for portal names beginning with "ل".
-- [[Module:Portal/images/م]] - for portal names beginning with "م".
-- [[Module:Portal/images/ن]] - for portal names beginning with "ن".
-- [[Module:Portal/images/و]] - for portal names beginning with "و".
-- [[Module:Portal/images/ه]] - for portal names beginning with "ه".
-- [[Module:Portal/images/ی]] - for portal names beginning with "ی".
-- [[Module:Portal/images/دیگر]] - for portal names beginning with any other letters. This includes numbers,
-- letters with diacritics, and letters in non-Latin alphabets.
-- [[Module:Portal/images/مستعارها]] - 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.
