[OpenLayers-Users] How to add attribution to this layer?

[Scott Chapman]

I don't know how to add an attribution property to the baseOSM layer
below.  I want to be able to display an attribution line on the map
saying where the data comes from, etc.

        var arrayOSM =
["http://otile1.mqcdn.com/tiles/1.0.0/osm/${z}/${x}/${y}.jpg",

"http://otile2.mqcdn.com/tiles/1.0.0/osm/${z}/${x}/${y}.jpg",

"http://otile3.mqcdn.com/tiles/1.0.0/osm/${z}/${x}/${y}.jpg",

"http://otile4.mqcdn.com/tiles/1.0.0/osm/${z}/${x}/${y}.jpg"];
        var baseOSM = new OpenLayers.Layer.OSM("MapQuest-OSM Tiles", arrayOSM);

Thanks!
Scott
