Illustrator CS5 center on artboard

Hi you all,

I have a lot of SVG-files.
All elements of the file are within a clippingmask.
The whole drawing is more or less off center from the artboard.
All I want is select the whole thing and center it on the artboard and then save it as eps and svg-file.

Manual this is easy (just select all and two clicks on the align-pallet), but how does this work with Applescript.

Can anyone help me with this.

Thanks in advance

Erwin

Is all your art in the one clipped group?
