Utilisateur:Phe/Works about.js

// when acting on an Author: page try to find works about this author.
//
// An associative array of basename prefix associated with a two entry array,
// array[0] describe how to build a page title, array[1] describe how to build
// a link to such page.
// Parameters substitution is done this way:
// %0 is the target base pagename
// %A: lastname, firstname
// %B: firstname lastname
// %1: the title matching the subpage name
// Don't add more than 50 entry.
//
// Only one request for the full set of name is done, adding more entry doesn't
// require more request.
//
// Only article following the base_pagename/article_name convention can
// go in this array, other special case, like DBN00, are hard-coded.
