+#   According to pypa/pipenv#598, it is recommended to include Pipfile.lock in version control.

+# poetry
+#   Similar to Pipfile.lock, it is generally recommended to include poetry.lock in version control.
+#   This is especially recommended for binary packages to ensure reproducibility, and is more

+#   Similar to Pipfile.lock, it is generally recommended to include pdm.lock in version control.
