+SUMMARY = "WebP is an image format designed for the Web"
+DESCRIPTION = "WebP is a method of lossy and lossless compression that can be \
+               used on a large variety of photographic, translucent and \
+               graphical images found on the web. The degree of lossy \
+               compression is adjustable so a user can choose the trade-off \
+               between file size and image quality. WebP typically achieves \
+               an average of 30% more compression than JPEG and JPEG 2000, \
+               without loss of image quality."
