#!/usr/bin/env python
# pip installs packages using pinned package versions. If CERTBOT_OLDEST is set
# to 1, tools/oldest_constraints.txt is used, otherwise, tools/requirements.txt
# is used. Before installing the requested packages, core Python packaging
# tools like pip, setuptools, and wheel are updated to pinned versions to
# increase stability of the install.
#
# cryptography is currently using this script in their CI at
# https://github.com/pyca/cryptography/blob/14d45c2259b01f1459eeab8bb7d85ce4cfb0841b/.github/downstream.d/certbot.sh#L8-L9.
# We should try to remember to keep their repo updated if we make any changes
# to this script which may break things for them.
