+long_desc="
+ Cairo is a vector graphics library with cross-device output support. Currently
+ supported output targets include the X Window System and in-memory image
+ buffers. PostScript and PDF file output is planned. Cairo is designed to
+ produce identical output on all output media while taking advantage of display
+ hardware acceleration when available (eg. through the X Render Extension).
+
+ Cairo provides a stateful user-level API with capabilities similar to the PDF
+ 1.4 imaging model. Cairo provides operations including stroking and filling
+ Bezier cubic splines, transforming and compositing translucent images, and
+ antialiased text rendering."
