  Minimal clang-rename integration with Vim.
  
  Before installing make sure one of the following is satisfied:
  
  * clang-rename is in your PATH
  * `g:clang_rename_path` in ~/.vimrc points to valid clang-rename executable
  * `binary` in clang-rename.py points to valid to clang-rename executable
  
  To install, simply put this into your ~/.vimrc
  
      noremap <leader>cr :pyf <path-to>/clang-rename.py<cr>
  
  IMPORTANT NOTE: Before running the tool, make sure you saved the file.
  
  All you have to do now is to place a cursor on a variable/function/class which
  you would like to rename and press '<leader>cr'. You will be prompted for a new
  name if the cursor points to a valid symbol.
