# We specify a generic language instead of C++ as Travis sets up
# additional environment vars that point to its default toolset
# instead of the one we install. The extra env doesn't interfere,
# but at the same time it's misleading. So to avoid confusion and
# possible unseen side effects we stick with no C++ default setup.
language: generic

# Because we install our own toolsets and other software we need
# to run the sudo support.
sudo: required

    # The various GCC's and Clang's available for Ubuntu Bionic.
