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. Since every package has its own version number, the version number quoted only refers to the version of scrbook, scrreprt, scrartcl, scrlttr2 and typearea (which are the main parts of the bundle).
