The syntax defined in this PEP is for use with Python distribution
metadata files. The file format is a simple UTF-8 encoded Key: value
-format with no maximum line length, followed by a blank line and an
-arbitrary payload. The keys are case-insensitive. It is parseable by
-the ``email`` module with an appropriate ``email.policy.Policy()``.

When ``metadata`` is a Unicode string,
```email.parser.Parser().parsestr(metadata)`` is a serviceable parser.
