# 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.
