Sangeeta,
Thanks for this question. You'll need to provide your own custom package
(not the Babel package) for splash screen/about box integration. Babel
doesn't provide any facility for this feature.
Your custom package doesn't really have to do anything if you don't want it
to, it can exist solely for the purpose of the splash screen, about box.
In the future, we're hoping to get a better mechanism for this that doesn't
require an entire package, but that is the way VS works today.
Hope this helps,
