    NAME

         SelectSaver - save and restore selected file handle
    
    
    

    SYNOPSIS

             use SelectSaver;
    
             {
                my $saver = new SelectSaver(FILEHANDLE);
                # FILEHANDLE is selected
             }
             # previous handle is selected
    
             {
                my $saver = new SelectSaver;
                # new handle may be selected, or not
             }
             # previous handle is selected
    
    
    
    

    DESCRIPTION

         A `SelectSaver' object contains a reference to the file
         handle that was selected when it was created.  If its `new'
         method gets an extra parameter, then that parameter is
         selected; otherwise, the selected file handle remains
         unchanged.
    
         When a `SelectSaver' is destroyed, it re-selects the file
         handle that was selected when it was created.
