+   (description
+    "T1lib is a library for generating/rasterising bitmaps from Type 1 fonts.
+It is based on the code of the X11 rasteriser of the X11 project.
+
+The bitmaps created by t1lib are returned in a data structure with type
+GLYPH. This special GLYPH-type is also used in the X11 window system to
+describe character bitmaps. It contains the bitmap data as well as some
+metric information. But t1lib is in itself entirely independent of the
+X11-system or any other graphical user interface. ")
