-#X text 25 160 Be careful : if masses are deleted \, lists messages
-won't work;
-#X text 25 65 It is designed to implement particules physical model
-in PD.The model is based on two elements type : mass and link. The
-msd masses are the principals objects of the model. They got only one
-physical parameter \, the value of their mass. They can be mobile or
-fixed \, in this case forces applied on them automatically \, by links
-\, or manually \, by messages \, don't do anything.;
-#X text 25 262 Links can be created between mutiples masses \, instead
-of creation number \, the masses linked are defined with their Id.

+msd masses are the principals objects of the model. They got only one

+fixed \, in this case forces applied on them automatically \, by links
+\, or manually \, by messages \, don't do anything.;
