# NOTE: If you're looking here because python-*-profile.tar.xz is missing:
# - thanks for upgrading Python!
# - files/python3_gen_pgo.sh should be able to generate a PGO profile for you.
# - only new minor versions of Python should require a new PGO profile.
#
# Generally, PGO profile generation should be done as one of the last steps of
# a Python upgrade, so feel free to turn pgo_use off as a default until things
# are pretty finalized.
