Rather make it a sentence: “This tool checks Python code ...”.

OK with this change, thanks!

Rather: “PyFlakes statically checks Python source code for common
errors, such as FOO and BAR.”

OK with a change along these lines.

Thanks,
Ludo’.

I’m just guessing, but rather something like: “This package provides a
Flake8 plug-in to compute the McCabe cyclomatic complexity of Python
source code.”

OK with such a change.

Thanks,
Ludo’.

Don’t write a bullet list since it’s formatting would be lost in the
various UIs.

OK with these changes.

Thank you!
