         '   Voltage Stability Toolbox (VST) is a powerful software package, developed '        
         '   in Center for Electric Power Engineering, Drexel University, to analyze   '
         '   voltage stability phenomena and provide intuitive information for power   '
         '   system planning, operation,and control. It can also be used to implement  '
         '   load flow calculations. VST is a portable software package that combines  '
         '   computational and analytical capabilities of bifurcation theory, and      '
         '   symbolic implementation and graphical representation capabilities of      '
         '   MATLAB and its Toolboxes.                                                 '
