'|float| or |Length| value specifying the space between baselines in
successive lines of the paragraph. A value of |None| indicates line
spacing is inherited from the style hierarchy. A float value, e.g.
``2.0`` or ``1.75``, indicates spacing is applied in multiples of
line heights. A |Length| value such as ``Pt(12)`` indicates spacing
is a fixed height. The |Pt| value class is a convenient way to apply
line spacing in units of points. Assigning |None| resets line spacing
to inherit from the style hierarchy.'
