+#X text 30 25 The aim of this collection of objects is to create physical
+behavior with pure data. It's not audio synthesis. But it can be used
+for the creation of parameters that can be used for driving an audio
+or video synthesis.;
+#X text 30 101 Most of the examples use GEM \, to allow visualization
+of the "physical" geometry \, but you don't need it to use this collection.

+#X text 34 30 Object in this collection can be mass \, link and interactor
+\, in 1D \, 2D or 3D.;
+#X text 47 69 Masses (mass \, mass2D \, mass3D) are ponctual. They've
+got a weight \, and know their position. They can move when they receive
+a force \, acording to physical rules.;
+#X text 47 126 Link (link \, link2D \, link3D) are the basic interaction
+beetween 2 masses. It is a visco-elastic link. The link object receive
+the position of 2 masses \, compute the force beetween the 2 masses
+and output a force for each mass.;
+#X text 47 202 Interactors are a kind of link \, but influence a group
+of masses at once. They can be used for global interaction. We will
+look further into it later.;
+#X text 32 272 This collection of objects can be interconnected for
+the creation of "physical" structures. Such structures can then move
+\, and distord themselves \, according to forces applied to them.;
+#X text 29 350 The resulting movements are very natural \, due to the
+physical equations used to define the objects.;
+#X text 30 418 all objects can be created using pmpd.name \, instead
+of name in order to avoid name conflict between libraries.;

+only have "cold" inlets. The computation speed depends on an external
+metronome. This metronome should bang alternatively all links in the
+model and then masses of the model.;
+#X text 33 103 mass and link have a name corresponding to their class
+name. They will receive everything sent to this name.;
+#X text 159 236 clicking on bang 1 or 2 is equivalent;
+#X text 32 304 As you sould send a bang alternatively to links and
+masses \, you sould give diferent names to the links group and masses
+group.;
+#X text 36 361 Masses output their position when you bang them. This
+position depends on the forces applied to the mass.;
+#X text 36 401 Links output a force according to the position of the
+masses when you bang them. This force sould be applied to the same
+mass.;

+move. It is useful for creating a structure attached to a fixed point.

+#X text 41 427 look at the structure \, and look a the patch : a lia

+#X text 40 486 to make your own strucute :;
+#X text 59 546 put "tut_masse" object in the screen where you want
+to put your masse in the gem windows.;
+#X text 58 658 create a "tut_lia" object for each link you whant to
+put in the structure.;
+#X text 60 726 The structure is ready. you should now do the initialisation
+part :;
+#X text 222 19 <- init;
+#X text 375 20 <- reset;
+#X text 59 763 click on pd init : this will give a minimal and maximal
+position to the masse. (for them to stay on the screen).;
+#X text 60 806 click on reset : this will tell the link to learn there
+good initial lenght \, reset forces etc...;
+#X text 59 584 when all masse are there \, you can specifie them ther
+initial position : edit "tut_masse" object and add 2 float corresponding
+to ther X and Y position in the GEM screen. (should be about from -4
+to 4);
+#X text 59 694 connect them to the masse (link and masses as to be
+connected in 2 way : mass to link and link to mass).;
+#X text 61 846 now \, you are ready for toggle the metro on...;

+#X text 47 69 Masses (mass \, mass2D \, mass3D) are ponctual. They've
+got a weight \, and know their position. They can move when they receive
+a force \, acording to physical rules.;
+#X text 47 126 Link (link \, link2D \, link3D) are the basic interaction
+beetween 2 masses. It is a visco-elastic link. The link object receive
+the position of 2 masses \, compute the force beetween the 2 masses
+and output a force for each mass.;
+#X text 47 202 Interactors are a kind of link \, but influence a group
+of masses at once. They can be used for global interaction. We will
+look further into it later.;
+#X text 32 272 This collection of objects can be interconnected for
+the creation of "physical" structures. Such structures can then move
