Warning
This should not be used anymore!
This turned out to be the wrong solution for a problem better solved by moving to the use
of pyproject.toml. A tool for helping with that has been made available at OctoPrint/octoprint-plugint-tool.
Please use that instead.
Setuptools helpers for installing OctoPrint & OctoPrint plugins. Provided as a separate package to allow for easy reuse and as build dependency for OctoPrint plugins.
