In our example, we simply use packages=setuptools.find_packages(). In most cases this will work just fine, but it's important to understand what it does. The find_packages function looks through all the directories within the given directory and adds it to the list if it has an file inside. So instead of find_packages() you can generally use ['your_package'] instead. If you have several packages however, that tends to get tedious. That's where find_packages() is useful; simply specify some inclusion parameters (second parameter) or some exclusion parameters (third parameter) and you'll have all the relevant packages within your project. For example:

packages = find_packages(exclude=['tests', 'docs'])
