+for header/footer and page dimensions.  Most common paper sizes, paper
+orientation, disabling of headers and footers, and two sided printing are
+supported.
+
+The user interface might not be very fancy, but it's fast, small, and gets the
+job done.  If you are looking for something more elaborate try the
+@code{geometry} package.")
