# WARNING:
# The installation will only succeed if the built cryptography wheel is for the
# same version of the cryptography package as the one documented in `setup.py`.
# If not, `make setup` will try to install the right version, which will fail.
# To avoid this, we create a `constraints.txt` file that constrains the version
# of `cryptography` extracted from the `setup.py` file
