 TensorFlow builds are configured by the `.bazelrc` file in the repository's
 root directory. The `./configure` or `./configure.py` scripts can be used to
 adjust common settings.

-TensorFlow dependencies and asks for additional build configuration options
-(compiler flags, for example). Refer to the _Sample session_ section for
