-          A good test that uses libraw.dylib to open and convert a RAW image
-          to tiff was delayed until the RAW test image from the Internet is in your
-          cache. To download that image and run the test, simply type
-
-             brew fetch #{netraw}
-             brew test libraw
-
-          It's a fairly small image, 4 MB, that takes less time to download than
-          read this.  Please ignore the harmless message from brew fetch about
-          No Available Formula.  Brew fetch works correctly as does this well
-          written software.
