-## Requirements
-
-### libclang
-
-This tool requires libclang. Any version that is 3.1 or later and binary compatible with 3.1
-should work. Either download the pre-compatible libraries from the LLVM site or use libclang
-shipping with your system or available from the system package manager.
-
-Some header files will require "stdarg.h" and/or "stddef.h". These are so called builtin
-includes and are shipped with Clang. They need to be placed in the standard header locations
-or explicitly referenced with the `-I` flag. For more information see the
-[Clang FAQ](http://clang.llvm.org/docs/FAQ.html#i-get-errors-about-some-headers-being-missing-stddef-h-stdarg-h).

-Download the pre-compiled libraries here:

-Alternatively compile libclang yourself:

-    $ git clone http://llvm.org/git/llvm.git
-    $ cd llvm
-    $ git checkout release_31
-    $ cd tools
-    $ git clone http://llvm.org/git/clang.git
