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 solving, the tool will solve and set up the mesh and joints (with "_vast" appended to the mesh name) in the scene. 

In Maya, the command vast is provided, and the command flags are the same as the parameters displayed in the GUI. 

There is a User Guide that contains the command documentation.
