// A monobook.js-be iktatva megjelenít a lapokon felül egy új fület.
// A fülre kattintva - némi várakozás - után az éppen szemlélt lapon  
// bezöldülnek a REDIR-re mutató belső hivatkozások.
// 
// Így iktassad be a Special:Mypage/monobook.js lapodra:
//
// mw.loader.load('http://hu.wikipedia.org/w/index.php?title=Wikip%C3%A9dia:Okos_scriptek/z%C3%B6ldredir.js'

// Ne felejtsd el kiüríteni utána a cache-t ! (CTRL+R)
//
// FIGYELEM! Ősrégi cucc, nagy valószínűséggel nem működik, egyébként is van
// már CSS-verzió, ami bekapcsolható a segédeszközöknél.
