  15 This manual is for `sketch', version 0.2 (build 161),
  16 Tuesday, September 08, 2009, a program that converts descriptions of simple
  17 three-dimensional scenes into static drawings. This version generates
  18 `PSTricks' or `PGF/TikZ' code suitable for use with the
  19 TeX document processing system.

  60 point (including the original) with straight line segments to form a
  61 polyline.  If there are m points in the original point list,

  64 objects (polylines) from zero-dimensional ones (points).

  70 to form a polygon with <var>n</var> sides.  If there are m points in
  71 the original point list, then m polygons with <var>n</var> sides
  72 each are formed by the sweep.  In this manner, <code>sweep</code> forms a

  74 (points).
