 JNI wrapper to convert JPEG and PNG to WebP
+
+### Mac OS X
+Before build native library it's needed to install libpng, libwebp and jpeg-turbo:
+
+Using brew:
+```
+   brew install libpng
+   
+   brew install webp
+   
+   brew install jpeg-turbo
+ ```
+For build libonewebp.dylib:
+```
+ant clean webp-dll -Djpeg-turbo.version=2.0.0 -Dlibpng.version=1.6.35 -Dlibwebp.version=1.0.0
+```
