 # This package contains a cross toolchain to compile for MacOSX. It bundles:
-# * MacOSX 10.11 SDK
+# * MacOSX 10.13 SDK
 # * wrapper for Clang provided by osxcross
 # * wrapper and toolchain file for using Clang with CMake
-# * GCC toolchain (including libstdc++) which is built using the script provided by osxcross
-#   Note that GCC is only available for i386, x86_64 but not for x86_64h
 # * symlinks for ccache, so it will be used when cross compiling if it is enabled in /etc/makepkg.conf
 
 # Difference between this package and osxcross-git maintained by emersion in the AUR:
 # * osxcross-git does not stick to a particular commit
-# * osxcross-git does not provide GCC toolchain (only Clang wrapper)
-# * osxcross-git does not provide CMake toolchain file
+# * osxcross-git does not provide CMake wrapper scripts
 # * osxcross-git violates "package etiquette" by putting stuff under /usr/local/osxcross (this package
 #   uses /opt/osxcross)
 # * osxcross-git will likely not work for building other apple-darwin-* packages provided
