title: How to add multiple kernel versions to local repo manifest
body: <p>I followed this <a href="http://elinux.org/Android_Kernel_Download" rel="nofollow">link</a> to create a local manifest to download a particular version of android kernel as follows:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;manifest&gt;
  
    &lt;remote  name="aosp"
             fetch=".."
             review="https://android-review.googlesource.com/" /&gt;
    &lt;default revision="master"
             remote="aosp"
             sync-j="4" /&gt;
  
     &lt;project path="kernel/common" name="kernel/common" revision="android-4.4"/&gt;
  &lt;/manifest&gt;
  </code></pre>
  
  <p>And synced using <code>repo sync kernel/common</code></p>
  
  <p>How should I proceed for syncing multiple kernel versions.</p>
