These are my highly customized vim configurations.
Installation
See into install.sh and you'll hopefully figure out how to install.
That file is more like an instruction, it might not simply work on different machines.
If you don't need YCM or if you don't have proper version of libclang installed in your system, please comment the lines in install.sh and compile YCM yourself. For the details, please see the doc of YCM.
See vimrc for details on my configurations.
