SelectSaver(3)
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
      }

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.
