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 han-
     dle 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.
