  Osname.Contains ("Win")? "Win":
  Osname.Contains ("Mac")? "MacOSX":
// osname.contains ("Linux") || Osname.Contains ("nix")? "Linux_GTK":
// Linux Version Is To Come Yet
  NULL;
if (SWTFILENAME == NULL)
 Throw New RuntimeException ("Unknown OS Name:" + Osname);
SWTFILENAME + = osarch.contains ("64")? "64": "32";
