 GEGL (Generic Graphics Library) is a graph based image processing framework.
 
-GEGL is a raster compositing and processing core. It provides a framework for
-organizing operations into nodes in a graph that can contain cached states to
-improve re-render performance. It currently implements a set of 32bit floating
-point buffer operations for filters, video frame loading, file loading, pattern
-generation, webcam input. As well as operations for storing individual frames,
-generate video sequences or displaying the result in fullscreen.
-
-GEGL's original design was made to scratch http://www.gimp.org/[GIMP]'s itches
-for a new compositing and processing core. This core is being designed to have
-minimal dependencies. and a simple well defined API.
-
+GEGL provides infratructure to do demand based cached non destructive image
+editing on larger than RAM buffers. Through link:http://gegl.org/babl/[babl]
+it provides support for a wide range of color models and pixel storage formats
+for input and output.
