How to document an exception using Sphinx?

You can use a backslash for line continuation:

def some_funct():
    """
    :raises ExceptionType: Some multi-line \
        exception description.
    """

Update:

Indenting seems to work instead of escaping the newline:

def some_funct():
    """
    :raises ExceptionType: Some multi-line
        exception description.
    """
