 Tensor Runtime and the DNN sources using the Tensor runtime are built with the unified HPVM build system. These 
 can also be separately built. HPVM Tensor Runtime can be built as:

 The tensor runtime is built as a static library under `build/lib/liibtensor_runtime.a`

-- `tensor_runtime/include/tensor_runtime.h` declares all the functions available in the runtime.

-  TODO: the tensor runtime is generally under-documented at the time.
-  More documentation will be added in the first public release.
 
 - For examples of using `tensor_runtime` functions, see `dnn_sources/src/alexnet_cifar10.cc`.
   - Also, try running `build/alexnet_cifar10` which is compiled from that file and runnable out of the box.
