/* This script adds a "Sort keys API" link under "Tools" in the sidebar on category pages.
   The link goes to an API page which shows sort keys for pages in the category.
   See WP:SORTKEY for sort key guidelines.
   The API is meant for programs but also readable for humans.
   If all category members are not shown then see the next group by manually copying the
   cmcontinue= value at top of the page to the end of the url. Omit the quotation marks.
   To use the script, add the following line to Special:MyPage/common.js:
 
importScript('User:PrimeHunter/SortkeysAPI.js'); // Linkback: [[User:PrimeHunter/SortkeysAPI.js]]

   See User:Nux/CategorySortKeys.js for an alternative script which displays the sort keys
   in parentheses directly on the category page. Both scripts can be used at the same time.
