+It's particularly good at processing large images, working with colour,
+scientific analysis, and general research & development.
+
+Compared to most image processing libraries VIPS needs little RAM and runs
+quickly, especially on machines with more than one CPU core.  This is primarily
+due to its architecture which automatically parallelises the image workflows.")
