Description

Implementation of certain parts of Knuth's METAFONT program, concerning the drawing of curves by means of cubic splines. The main reason for following METAFONT is its algorithm for assigning control points when the user does not do so, and the versatitility with which the user can provide partial information toward the assignment of control points.
