Get version stored in client.wyc

I need to extract the version number of the current installation. The Assembly version does not work for me because the main assembly of my application does not get updated as often as various other components (plus, the obfuscation we use also changes this value). Looking at the file I see that it's a zip, containing iucclient.iuc which does contain the version number... but if I'd rather not dig that deep. Is there some API that ships with wyBuild that does this? Or something in the wyUpdate source.

Thanks
