     1.4 +Spiro is the creation of Raph Levien. It simplifies the drawing of beautiful
     1.5 +curves.
     1.6 +
     1.7 +Using bézier splines an artist can easily draw curves with the same slope on
     1.8 +either side of an on-curve point. Spiros, on the other hand, are based on
     1.9 +clothoid splines which make it easy to maintain constant curvature as well as
    1.10 +constant slope. Such curves will simply look nicer.
    1.11 +
    1.12 +Raph Levien's spiro splines only use on-curve points and so are easier to use
    1.13 +and more intuitive to the artist.
    1.14 +
    1.15 +This library will take an array of spiro control points and convert them into
    1.16 +a series of bézier splines which can then be used in the myriad of ways the
    1.17 +world has come to use béziers.
