This is a scratchpad for topics we'd like to add or cover more comprehensively in the book:

• Dependency updating with Dependabot. This would fit nicely in the cookiecutter and book.
• Advanced fixture usage:
  • Mocking
  • Setting up environments for test to run in, e.g., directory structures, environment variables, etc.
• Style checking and formatting:
  • Using flake8 and/or black, and integrating into CI
• Packages with extensions in other languages (relevant comment)
• Releasing packages to Anaconda/conda-forge repositories
• Mention PyScaffold as an alternative templating tool
• Consider changing poetry to pdm (see discussions in #95)
• Consider providing more guidance on file/directory/repository/distribution/package naming conventions (see https://github.com/py-pkgs/py-pkgs-cookiecutter/issues/48 and this post)
• Consider adding more information/examples about namespace packages - currently we only briefly mention them at the bottom of [Section 4.2.1](https://py-pkgs.org/04-package-structure#package-contents (see #119)
