+     "The package lets you change page layout parameters in small steps over
+a range of values using options.  It can set @code{\\textwidth} appropriately
+for the main fount, and ensure that the text fits inside the printable area of
+a printer.  An rmpage-formatted document can be typeset identically without
+@code{rmpage} after a single cut and paste operation.  Local configuration can
+set defaults: for all documents; and by class, by printer, and by paper size.
+The @code{geometry} package is better if you want to set page layout
+parameters to particular measurements.")
