Overlaying Multiple KML files on google Map displayed in the browser

Question

Need to know the procedure for overlaying multiple KML files on a single Google Map that is displayed in the browser. The KML files intended for this can point to different locations. Ex:KML1 for North America & KML2 for Asia. Could anyone help me out in this.
