#    and update the sha256 with the result.

# For development, one often wants to make changes to the OpenXLA repository as well

# local checkout by either:
# a) overriding the OpenXLA repository on the build.py command line by passing a flag
#    like:
#    bazel --override_repository=xla=/path/to/openxla
#    or
# b) by commenting out the http_archive above and uncommenting the following:
# local_repository(
#    name = "xla",
#    path = "/path/to/openxla",
