-# Since ~2020-11 ansible renamed "ansible-base" to "ansible-core".
-# Unfortunately, ansible-base and ansible-core can not live happily
-# together.  For testinfra, our tox role pre-installs the requirements
-# from tox.ini (ansible-base) but then tries to install siblings (the
-# checked out ansible tree, now trying to install the "ansible-core"
-# package).  There is no working "ansible-core" package on PyPi, so
-# for now we have to switch this out in the tox.ini for the -devel job
-# to work.  We can remove this when "ansible-core" is published at an
-# appropriate version on PyPi; at that point the checked-out tree can
-# override the package in the testing tox venv.
