The KOMA-Script bundle provides replacements for the article, report, and book classes with emphasis on typography and versatility. There is also a letter class. The bundle also offers: a package for calculating type areas in the way laid down by the typographer Jan Tschichold, packages for easily changing and defining page styles, a package scrdate for getting not only the current date but also the name of the day, and a package scrtime for getting the current time. All these packages may be used not only with KOMA-Script classes but also with the standard classes.
