// Recent Rivison Box by JePe@nlwiki

// (nl) Dit script leest de meest recente bewerkingen van een pagina
// uit de MediaWiki API en plaatst die in een box in de zijbalk
// boven de navigatie na het indrukken van een knop. In de box staan de
// gebruikersnamen met een link naar de betreffende paragraaf. 
// Voor de naam staat het tijdstip van de bewerking met een
// link die een diff met het verschil tussen de vorige bewerking
// boven de pagina plaatst. In de tooltip staat de bewerkingssamenvatting.
