+For building the OSX versions we install the Xcode commandline tools and build
+pkg-config from source as well as static versions of the libraries listed above.
+This helps keep the dependencies to a minimum so end users can use the tools
+with only Xcode command line tools to obtain make.

 To avoid having to manually answer prompts during the build the script will
 read variables from config.sh if it exists. Copy config.sh.sample to config.sh
 and set the variables as appropriate for your build.

-Using devkitPSP
----------------

-All you need to do now to use devkitPSP is make sure that your freshly built tools
-are in your PATH, something like this;

-export PATH=$PATH:<path to devkitPSP>/bin
