+Xgas, animated simulation of an ideal gas
+
+Xgas is a physical simulation of an ideal gas in a heated box. 
+Gas molecules move around the box with velocities dependent on
+their temperature. A chamber consisting of two boxes contains 
+the gas molecules collide with the walls, their temperature 
+approarches that of the box.
+
+Use  mouse  button  1 to create molecules one at a time at
+the cursor position.  Use mouse button  2  to  create  the
+maximum number of molecules at the cursor position.
+
+Usage: xgas [ -options ]
+
+Options:
+      -as   Sets the autoStart resource.
+      -ts   Sets the timeStepSize resource.
+      -d    Sets the delay resource.
+      -rb   Sets the randomBounce resource.
+      -eq   Sets the equilibrium resource.
+      -mm   Sets the maxMolecules resource.
+      -fg   Sets the foreground.
+      -bg   Sets the background.
