# History:
# 1.0 (08/10/2012): First public version, supports Xcode up to version 4.6.3
# 1.1 (20/09/2013): Xcode 5 removed llvm-gcc and 10.7 SDK support, grab them from Xcode 3 and 4
# 1.2 (03/02/2014): Xcode 5 broke PPC assembly and linking; fix assembly and grab linker from Xcode 3
# 1.3 (07/10/2014): Xcode 6 removed 10.8 SDK, grab it from Xcode 5.1.1
# 1.4 (21/08/2015): Xcode 7 removed 10.9 and 10.10 SDKs, grab them from Xcode 6.4
