 % Obviously it will need some work.
-Xr and Xc provide an antialiased vector-based rendering API for the X
-Window System. Xr provides a stateful user-level API with support for
-the PDF 1.4 imaging model. Xr provides operations including stroking
-and filling Bezier cubic splines, transforming and compositing
-translucent images, and antialiased text rendering.
+Xr provides a vector-based rendering API with output support for the X
+window system, local image buffers and plans for PostScript and PDF files.
+Xr is designed to produce identical output on all output media while
+taking advantage of display hardware acceleration through the X RENDER
-Xc sits below Xr and provides an abstraction layer over the backend
-rendering system. Xc allows the graphics operations to target X server
-drawables or client-side image buffers. Xc takes advantage of the
-RENDER extension if available and performs client-side emulation of
-RENDER for legacy X server.
+Xr provides a stateful user-level API with support for the PDF 1.4 imaging
+model. Xr provides operations including stroking and filling B\'ezier cubic
+splines, transforming and compositing translucent images, and antialiased
+text rendering.  The PostScript drawing model has been adapted for use
+within C applications.  Extensions needed to support much of the PDF 1.4
+imaging operations have been included.  This integration of the familiar
+PostScript operational model within the native application language
+environment provides a simple and powerful new tool for graphics application
