-# Xcode supports build variable substitutions and CPP; sadly, that doesn't work
-# because:
-#
-# 1. Xcode wants to do the Info.plist work before it runs any build phases,
-#    this means if we were to generate a .h file for INFOPLIST_PREFIX_HEADER
-#    we'd have to put it in another target so it runs in time.
-# 2. Xcode also doesn't check to see if the header being used as a prefix for
-#    the Info.plist has changed.  So even if we updated it, it's only looking
-#    at the modtime of the info.plist to see if that's changed.
-#
-# So, we work around all of this by making a script build phase that will run
-# during the app build, and simply update the info.plist in place.  This way
-# by the time the app target is done, the info.plist is correct.
