[cfe-dev] Error in Tutorial for building tools using LibTooling and LibASTMatchers

[Manuel Klimek]

If you follow those steps:

mkdir ~/clang-llvm && cd ~/clang-llvm
git clone http://llvm.org/git/llvm.git

You'll have a directory ~/clang-llvm/llvm

Then, after
cd ~/clang-llvm
mkdir build && cd build

you'll have a ../llvm directory.

If you change the paths you'll need to adapt the commands to still work :)
