body: <p>I see references to, and examples that use </p>
  
  <pre><code>#+BEGIN_SRC bash
  </code></pre>
  
  <p>But in my org mode version (elpa, org 20150316) in the menu of <code>customize-variable org-babel-load-languages</code>, there is no "bash" item, only shell. Attempting to evaluate code such as </p>
  
  <pre><code>#+BEGIN_SRC bash
  ls -l
  #+END_SRC
  </code></pre>
  
  <p>I get </p>
  
  <blockquote>
    <p>org-babel-execute-src-block: No org-babel-execute function for bash!</p>
  </blockquote>
  
  <p>What am I missing?</p>
  
  <p>Thanks.</p>
