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.
