+Python interpreter.  This library provides extensive file format support, an
+efficient internal representation, and fairly powerful image processing
+capabilities.  The core image library is designed for fast access to data
+stored in a few basic pixel formats.  It should provide a solid foundation for
+a general image processing tool.")
