+"""Xcode-ninja wrapper project file generator.
+
+This updates the data structures passed to the Xcode gyp generator to build
+with ninja instead. The Xcode project itself is transformed into a list of
+executable targets, each with a build step to build with ninja, and a target
+with every source and resource file. This appears to sidestep some of the
+major performance headaches experienced using complex projects and large number
+of targets within Xcode.
