/* Script:  [[User:TheDJ/Gadget-HotCat.js]]
// <nowiki>
  * HotCat: Adds an easy way to add, modify and remove categories
// Einfaches Hinzufügen und Entfernen von Kategorien in Artikeln.
  * Documentation: [[User:TheDJ/HotCat]]
// Von http://commons.wikimedia.org/wiki/MediaWiki:HotCat.js und
  * Originally written by: Magnus Manske
// http://fr.wikipedia.org/wiki/MediaWiki:JSScripts/HotCats übernommen
  *
// Version: 28. 11. 2007
  * This version was forked from http://commons.wikimedia.org/w/index.php?title=MediaWiki:Gadget-HotCat.js&oldid=10204404
 
  * In sync with version: http://commons.wikimedia.org/w/index.php?title=MediaWiki:Gadget-HotCat.js&oldid=19600669
// Konfigurationsvariablen:
  * Major changes:
// Zeit bis die Auswahlliste erscheint
  *  - all code for the uploadForm has been removed
var hotcat_suggestion_delay = 200;
  *  - autocommit is disabled
// Anzahl der Zeilen in der Auswahlliste
  *  - will be enabled on pages without categories so that you can easily add them
var hotcat_list_size = 10;
  *  - uses javascript:void() as a dummy value for href in order to avoid a conflict with popups.
// Anzahl der Elemente in der Auswahlliste
  *  - checks for {{Uncategorized}} and removes it if a category is added
var hotcat_list_items = 50;
  *  - does not use JSconfig for configuration options like its Commons original
// Wenn true: Automatisches Speichern der Änderung ohne Bearbeitungsfenster
  *  - tries to detect other categories and if possible, add to the end of them.
// var hotcat_autocommit = false;
  *  - fixes a bug in the suggestion list with titles containing : character
// Wenn true: Auswahlliste nach unten statt nach oben ausklappen
  *  - Uses opensearch API to look for categories. Allows for case insensitive search.
// var hotcat_list_down = false;
  *  - Postfix blacklisting in addition to prefix blacklisting.
 
  * [[User:TheDJ]] 2009-04-18
