NAME
    SelectSaver - save and restore selected file handle

SYNOPSIS
        use SelectSaver;

        {
           my $saver = SelectSaver->new(FILEHANDLE);
           # FILEHANDLE is selected
        }
        # previous handle is selected

        {
           my $saver = SelectSaver->new;
           # 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.
