How do I use shiv as a build backend to a PEP517-following project?

[JDLH]

I have a command-line Python application, which I would like to deploy as a shiv Python executable, and build using PEP518 and PEP517 conventions and a pyproject.toml file. Can I invoke shiv tooling in this scenario? Specifically, what value do I put for the [build-system] section's build-backend key?

I looked for this in the Shiv documentation. I could not find anything relevant. For example, searching for pyproject.toml did not turn up any hits.

I think the answer is: I don't. PEP 517 is only for tools which generate wheels and source distributions, and that is not what shiv does.
