This class implements a version of the OSF/Motif style file selection dialog box. This is a modified version of an older widget written by Mark Ulferts (before Iwidgets was released) that is still used because of poor performance in the iwidgets2.x version. This should probably be replaced with the new Tk version when we move to tcl8.x (Tk 8.x includes a standard file selection widget).
