title: Jinja Vim plugin not working
body: <p>I want to have my <code>.html.twig</code> files highlighted as Jinja files. (There doesn't seem to be a good Twig plugin for Vim out there, so I'm using Jinja instead.) I downloaded <code>jinja.vim</code> from <a href="http://www.vim.org/scripts/script.php?script_id=1856" rel="nofollow">here</a> and put the at <code>~/.vim/ftplugin/jinja.vim</code>. I also added these lines to my <code>~/.vimrc</code>:</p>
  
  <pre><code>filetype plugin on
  au BufRead,BufNewFile *.twig set filetype=jinja
  au BufRead,BufNewFile *.html.twig set filetype=jinja
  </code></pre>
  
  <p>However, when I open a <code>.html.twig</code> file, there's no syntax highlighting whatsoever. I haven't installed a Vim plugin before, so I'm guessing I missed some step. What am I doing wrong?</p>
