# setsweep options [arg1 [arg2 [...]]] : options are :
#    -FR : Tangent and Normal are given by Frenet trihedron
#    -CF : Tangente is given by Frenet,
#          the Normal is computed to minimize the torsion

# addsweep wire [Vertex] [-T] [-R] [u0 v0 u1 v1 [...[uN vN]]] : options are :
#    -T : the wire have to be translated to assume contact
#         with the spine
#    -R : the wire have to be rotated to assume orthogonality
#         with the spine's tangent

#    -C : Discontinuities are treated like Right Corner
#         Treatment is Extent && Intersect
#    -R : Discontinuities are treated like Round Corner
#         Treatment is Intersect and Fill
