+     "The extrafont package makes it easier to use fonts other than the basic
+PostScript fonts that R uses.  Fonts that are imported into extrafont can be
+used with PDF or PostScript output files.  There are two hurdles for using
+fonts in PDF (or Postscript) output files:
+
address@hidden
address@hidden Making R aware of the font and the dimensions of the characters.
address@hidden Embedding the fonts in the PDF file so that the PDF can be 
displayed
+  properly on a device that doesn't have the font.  This is usually needed if
+  you want to print the PDF file or share it with others.
address@hidden enumerate
+
+The extrafont package makes both of these things easier.")
