* RenderScript is a high-performance runtime that provides
* compute operations at the native level. RenderScript code is compiled on devices
* at runtime to allow platform-independence as well.
* This reference documentation describes the RenderScript runtime APIs, which you
* can utilize to write RenderScript code in C99. The RenderScript compute header
* files are automatically included for you.
*
* To use RenderScript, you need to utilize the RenderScript runtime APIs documented here
* as well as the Android framework APIs for RenderScript.
* For documentation on the Android framework APIs, see the <a target="_parent" href=
* "http://developer.android.com/reference/android/renderscript/package-summary.html">
* android.renderscript</a> package reference.
* For more information on how to develop with RenderScript and how the runtime and
* Android framework APIs interact, see the <a target="_parent" href=
* "http://developer.android.com/guide/topics/renderscript/index.html">RenderScript
* developer guide</a> and the <a target="_parent" href=
* "http://developer.android.com/resources/samples/RenderScript/index.html">
* RenderScript samples</a>.
