Installation Logs
I discovered that the tests folder is included in the package distribution, which I believe is not a good practice.
Consider this real scenario: I use pandas in an AWS Lambda function, where the layer size limitation is 250 MB. This means all dependencies must be smaller than this limit, necessitating a reduction in the package size.
Here is what setuptools says,
final users will end up installing not only timmins.foo, but also docs and tests.tests_foo. A simple way to fix this is to adopt the aforementioned src-layout, or make sure to properly configure the include and/or exclude accordingly.
How to reproduce it
$ pip install pandas -t test-install
$ cd test-install
$ du -sh * | sort -rh
