How to add labels to markers?

Hi,

I'm trying to figure out how to add labels to markers. I don't see options for it, or how I might even be able to code them in. I'm not talking about the tooltip titles, which go into 'opts' and are used for mouse overs. I'm talking about the persistent labels that display with the marker. There is support for it in the Google API as 'labelContent'. I'd be willing to modify Gmap to make them work, but everything I try to modify the markers array to add 'label' or 'labelContent' seems to not work.

Any help is appreciated.
