/* This script adds "Parameter links" below "What links here" in the sidebar.
   "What links here" will include pages using a template with the link or
   calling a template to produce the link.
   "Parameter links" tries to search for pages which produce the link by calling a
   link-making template with the page name as a parameter given in the source,
   for example {{Cat|Stubs}} to produce a link to [[:Category:Stubs]].
   It's an imperfect search and may not detect all wanted links correctly.
   To use the script, add the following line to [[Special:MyPage/common.js]]:
 
importScript('User:PrimeHunter/Parameter links.js'); // Linkback: [[User:PrimeHunter/Parameter links.js]]

  See [[PrimeHunter/Source links.js]] for a different script to search pages making a link with
  full link syntax directly in the source, for example [[:Category:Stubs]].
