Best practice - *-Info.plist

I’m looking for a recommendation of how to manage the *-Info.plist file, specifically related to git. I’ve read a number of recommendations to not check in the /platforms directory, which makes sense to me. But I’ve also seen a number of tutorials (Facebook SDK specifically) that say to manually modify the *-Info.plist file for configuration, which is negated if you don’t check that file in.

Opinions here? Checking in /platforms or not? And if not, how do you modify the *-Info.plist file?
