(*   GSAS-II AppleScript by B. Toby (brian.toby@anl.gov)
         It can launch GSAS-II by double clicking or by dropping a data file
         or folder over the app.
         It runs GSAS-II in a terminal window.
         
         Thanks to F. Farges (farges@univ-mlv.fr) for many applescript tricks
