what versions of setuptools / pip does the output work with?

• pip>=1.5 (when installing from a wheel)
  • released 2014-01-02
• setuptools>=30.3 (when building from source)
  • released 2016-12-08
• virtualenv>=15.2 (to get a sufficient setuptools via --no-download)
  • released 2018-03-21

what is not supported

declarative metadata does not support ext_modules or setuptools plugins -- those must stay in setup.py. If you're converting a project which uses one of those, you'll see a message like:

$ setup-py-upgrade ../future-breakpoint/
ext_modules= is not supported in setup.cfg

To convert those, temporarily remove the offending constructs from setup.py, then run setup-py-upgrade, then paste them back into the file.
