The vastSolver can be used as (1) a compact GUI tool or (2) an Autodesk® Maya® command. 

In the GUI mode, the user has to select a target mesh and set solving parameters. If the mesh animation is suitable for the solving, the tool will solve and set up mesh and joints (with "_vast" appended to the mesh name) in the scene. 

The Maya command vast is provided. The command flags are the same as the parameters displayed in the GUI. 

There is a User Guide that contains the command documentation.
