Bug#1148888: dh-python: please replace the "flit" autopkgtest dependency with python3-flit

[Alexandre Detiste]

Package: dh-python
Version: 7.20260623
Severity: normal

Dear Maintainers,

The Flit build engine has been spun out in the python3-flit package.

So please adapt d/test/control & replace "flit" with  "python3-flit".

Greetings

Alexandre
