3 This feature is designed to facilitate the typesetting of curved arrows, either singly or in pairs, together with labels on each part and between. The intended mathematical usage is for typesetting categorical ``2-cell'' morphisms and ``pasting diagrams'', for which special features are provided. These features also allow attractive non-mathematical effects.

3 The 2-cell feature makes use of facilities from the `curve' extension which is therefore automatically loaded.
