 // For pages that have something like Template:Lowercase, replace the title, but only if it is cut-and-pasteable as a valid wikilink.
 // (for instance iPod's title is updated. But [[w:en:C#|C#]] is not an equivalent
 // wikilink, so [[w:en:C Sharp|C Sharp]] doesn't have its main title changed)
 // Likewise for users who have selected the U.K. date format ("1 March") the  
 // titles of day-of-the-year articles will appear in that style. Users with any
 // other date setting are not affected.
 //
 // The function looks for a banner like this: 
 // &lt;div id="RealTitleBanner"&gt;  ... &lt;span id="RealTitle"&gt;title&lt;/span&gt; ... &lt;/div&gt;
 // An element with id=DisableRealTitle disables the function.
 //
 var disableRealTitle = 0; // users can set disableRealTitle = 1 locally to disable.
