-# flit_core>=3.4.0 requires tomli to run, while tomli requires flit_core to
-# build. Both upstreams are aware of the cycle, but neither cares:
-#     https://github.com/hukkin/tomli/issues/130
-#     https://github.com/takluyver/flit/issues/451
-# As a result, we can't use python3-flit_core to build this package, so we have
-# to just fetch the flit_core tarball to bootstrap tomli. Sigh.
