+%% Description of functions operating on planar lines.
+%
+%   The term 'line' refers to a planar straight line, which is an unbounded
+%   curve. Line segments defined between 2 points, which are bounded, are
+%   called 'edge', and are presented in file 'edges2d'.
+%
+%   A straight line is defined by a point (its origin), and a vector (its
+%   direction). The different parameters are bundled into a row vector:
+%   LINE = [x0 y0 dx dy];
+%
+%   A line contains all points (x,y) such that:
+%       x = x0 + t*dx
+%       y = y0 + t*dy;
+%   for all t between -infinity and +infinity.
