thanks, seems to work well!

I have a "MissingFeature" in a database, but when I ran this script with -reportonly it did not find it. It does show up in CA, and when I try to export the site it gives the error that the "MissingFeature" is not installed on the farm.

Missing Feature: Id = [75a0fea7-040e-4abb-b94b-32f1e7572840]
I believe it's a fab40 reference.

Any idea how you can remove a reference this script doesn't see?
