    """
    Return a dictionary mapping extension option names to converted values.

    :Parameters:
        - `field_list`: A flat field list without field arguments, where each
          field body consists of a single paragraph only.
        - `options_spec`: Dictionary mapping known option names to a
          conversion function such as `int` or `float`.

    :Exceptions:
        - `KeyError` for unknown option names.
        - `ValueError` for invalid option values (raised by the conversion
           function).
        - `TypeError` for invalid option value types (raised by conversion
           function).
        - `DuplicateOptionError` for duplicate options.
        - `BadOptionError` for invalid fields.
        - `BadOptionDataError` for invalid option data (missing name,
          missing data, bad quotes, etc.).
