+mechanisms using dedicate symbols (some from the ISO standard and others).
+The intention is not to represent CAD mechanical drawings of mechanisms and
+robots, but only to represent 2D and 3D kinematic chains.  The package
+provides links, joints and other symbols, mostly in the form of TikZ pic
+objects.  These pictures can be placed in the canvas either by a central point
+for joints, and start and end points for some links.")
