Schemes can't compose, so we have a number of places where we need to list all the targets we build in an "Everything" scheme. In open source, "Everything up to WebKit + Tools" must sync with "Everything up to WebKit" and "All WebKit Tools". Internally, there are many more points of duplication. Until and unless Xcode changes to better support scheme composition (rdar://100331407), let's write a checker that ensures the targets built by various schemes stay up-to-date.
