+page layout, implementing auto-centering and auto-balancing mechanisms so that
+the users have only to give the least description for the page layout.  The
+package knows about all the standard paper sizes, so that the user need not
+know what the nominal \"real\" dimensions of the paper are, just its standard
+name (such as a4, letter, etc.).  An important feature is the package's
+ability to communicate the paper size it's set up to the output.")
