/* 
	The tool generates a permanent-link wikicode just below the page header;
	for providing a hyperlink that edit summary needed per [[d:Q10729797|Copying within Wikipedia]]:
		[[w:en:Dragon Quest XI]] (version [[w:en:Special:PermanentLink/938554397|938554397]])
	
	You can set a homewiki by adding the following codes in your JS page:
		window.permanentlinkDefaultLanguage = 'en';
		window.permanentlinkDefaultProject = 'Wikipedia';
		window.permanentlinkStyle = ' (ver. %s)' // %s is the placeholder for the permanentLink
	Then the prefix would be omitted:
		[[:Dragon Quest XI]] (ver. [[:Special:PermanentLink/938554397|938554397]])
