Converts a relative path to an absolute path.
- $abs_path = $File::Spec->rel2abs( $destination ) ;
- $abs_path = $File::Spec->rel2abs( $destination, $base ) ;

+ $abs_path = File::Spec->rel2abs( $destination, $base ) ;
If $base is not present or '', then L<cwd()> is used. If $base is relative,
then it is converted to absolute form using L</rel2abs()>. This means that it
