.travis.yml

language: python
# https://docs.travis-ci.com/user/languages/python/
# Because the code depends a lot on the Python interpreter
# used (Python version and Python implementation), we want
# to test all the possible configurations, including
# deprecated versions.
# Also, on Travis, all versions do not exist on all distros
# (and when they do, they might actually correspond to
# different minor versions of the interpreter). Thus, we end
# end with a matrix to perform tests on different distros.
# Failure is allowed on versions that are known to be missing
# (these configs are tested anyway in case they come back).
