#!/usr/bin/env bash
#
#   Release script for a generic Python project using pyproject.toml
#
#   Run this from the root directory of the project to be released.
#   Generally used in conjunction with the instructions in `pypi-release`:
#     https://github.com/cynic-net/pypi-release
#
#   This is currently a hack that still needs a good bit of manual work
#   and checking, but it helps.
