## 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;

        }

## 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.
