 #ifdef WTF
 
 Provides a minimal wrapping of the Blink image decoders. Used to perform
 a non-threaded, memory-to-memory image decode using micro second accuracy
 clocks to measure image decode time. Optionally applies color correction
 during image decoding on supported platforms (default off). Usage:
 
   % ninja -C /out/Release image_decode_bench &&
-     ./out/Release/image_decode_beanch file [iterations]
+     ./out/Release/image_decode_bench file [iterations]
 
 FIXME: Consider adding md5 checksum support to WTF. Use it to compute the
 decoded image frame md5 and output that value.
 
 FIXME: Consider adding an input data packetization option. Break the input
 into network-sized packets, pump the packets into the image decoder until
 the input data is complete (allDataReceived). This to include any internal
 SharedBuffer costs, such as buffer coalescing, in the reported results.
 
 FIXME: Consider integrating this tool in Chrome telemetry for realz, using
 the image corpii used to assess Blink image decode performance. Refer to
 http://crbug.com/398235#c103 and http://crbug.com/258324#c5
