  50.     The Path tool allows to create complex selections called Bezier Curves,  
  51.     a bit like Lasso but with all the adaptability of vectorial curves. 
  52.     You can edit your curve, you can paint with your curve, or even save, 
  53.     import, and export the curve. You can also use paths to create 
  54.     geometrical figures. Paths have their own dialog box: Dialog/Paths.
