# Tox (https://tox.readthedocs.io) is a tool for running tests
# in multiple virtualenvs. This configuration file will run the tornado
# test suite on all supported python versions. To use it, "pip install tox"
# and then run "tox" from this directory.
#
# This configuration requires tox 1.8 or higher.
#
# Installation tips:
# When building pycurl on my macports-based setup, I need to either set the
# environment variable ARCHFLAGS='-arch x86_64' or use
# 'port install curl +universal' to get both 32- and 64-bit versions of
# libcurl.

# In theory, it doesn't matter which python version is used here.
# In practice, things like changes to the ast module can alter
# the outputs of the tools (especially where exactly the
# linter warning-suppression comments go), so we specify a
# python version for these builds.
# These versions must be synced with the versions in .github/workflows/test.yml
