My main peeve is that distutils2 died, and with it, the idea of putting package metadata (author, version, dependencies) in `setup.cfg` instead of `setup.py`.

It's bad enough that I have a boilerplate `setup.py` that just does `import ConfigParser` and blasts the entire `[setup.py]` section into `setuptools.setup()` as `kwargs`. I copy and paste this boilerplate into every new project that I start.

Oh and while we're ranting about Python packaging, let me rant about tox, which is so-very-useful but also so-very-dangerous: IF YOU (SLIGHTLY) MISCONFIGURE YOUR TOX.INI FILE, IT WILL DELETE YOUR ENTIRE PROJECT DIRECTORY! [1]

I suppose I am getting too old and cranky for this stuff. :)
