title: How do I vendorize gems for Rails3/Bundler
body: <p>In Rails 2.X, I could simply copy gems into <code>vendor/gems/gem_name</code>, or use the rake command <code>rake gems:unpack</code>. Since Rails3 uses bundler, it doesn't appear to work anymore. I have found the command <code>bundle package</code>, but it doesn't work the same way.</p>
  
  <h2>Edit:</h2>
  
  <p>So, just to elaborate a bit on this:</p>
  
  <p>The way that rails 2 worked, I could easily <em>grep</em> to find stuff in <code>vendor/gems</code>. If they are bundled up in <code>.gem</code> files, that isn't possible. Also, when developing a gem/plugin, it's very helpful to have it placed within a rails application to test it out in context. How would I do such things with bundler/rails3? Is my workflow inherently broken somehow?</p>
