 Tested with:
 
 * FFmpeg git commit f18ccb529fb7231f9d40814fbf843d10d9434b43
-* Xcode 4.6.3
+* Xcode 5
 
 Usage
 -----
 
-* To build armv7s libraries:
+* To build everything:
 
-        ./build-ffmpeg.sh armv7s
+	./build-ffmpeg.sh
 
-* To build fat libraries for armv7 and i386 (simulator):
+* To build arm64 libraries:
 
-        ./build-ffmpeg.sh armv7 i386
+        ./build-ffmpeg.sh arm64
+
+* To build fat libraries for armv7 and x86_64 (64-bit simulator):
+
+        ./build-ffmpeg.sh armv7 x86_64
 
 * To build fat libraries from separately built thin libraries:
