Can a program running in Racket VM introspect on itself to determine the names and versions of PLaneT packages that the program uses?

I tried poking around with environment introspection, and trying to follow module use graph that way, but no luck so far. Maybe this is something that modules rightfully hide?

The reason I want this is for the About box of an app: "http://i.imgur.com/TofUX.png";. I'd like to acknowledge the PLaneT packages the app uses, and indicate the version numbers for support/debugging purposes. I'd like to do this programmatically.

If I can't do this introspection, then I have a bunch of alternatives in mind that might work, but they're all messy and/or a chunk of work.
