My modified version of local vim rc script (auto loading of local rc file from up or current folder):

function SetLocalOptions()
    let dirname = getcwd()
    let predirname = dirname
 while 1
  let lvimrc  = dirname . "/.lvimrc"
  if filereadable(lvimrc)
   execute "source " . lvimrc
   break
  endif
  let dirname = fnamemodify(dirname, ":p:h:h")
        if dirname == predirname
            break
        else
            let predirname = dirname
        endif
 endwhile
endfunction

au BufNewFile,BufRead * call SetLocalOptions()
