# TODO(drpng): write up instructions for editing this file in a doc and point to
# the doc instead.
# If you want to edit this file to expose modules in public tensorflow API, you
# need to follow these steps:
# 1. Consult with tensorflow team and get approval for adding a new API to the
#    public interface.
# 2. Document the module in the gen_docs_combined.py.
# 3. Import the module in the main tensorflow namespace by adding an import
#    statement in this file.
# 4. Sanitize the entry point by making sure that your module does not expose
#    transitively imported modules used for implementation, such as os, sys.
