I'm currently writing a document that contains several code samples. I included them as lstlistings and played around with the colors and everything, so they loot quite nice now. My only problem is that in bigger code blocks it gets quite hard to keep track of the indentations, so I'd like to have those vertical lines that many IDEs and text editors have. Is there a way of including those automatically?
