      Eukleides is a computer language devoted to elementary plane
      geometry. It aims to be a fairly comprehensive system to create
      geometric figures, either static or dynamic. Eukleides allows to
      handle basic types of data: numbers and strings, as well as
      geometric types of data: points, vectors, sets (of points), lines,
      circles and conics.
