anchor.diff:  `cd` into the release directory.
   This is where all the BOSH commands in this tutorial are run from here on.
   
  +### <a id="directory-structure"></a> Directory structure on job VMs ###

   View the release with `tree`:
   
   <pre class="terminal">
  
positive.code: 
  Notice that in the release directory, BOSH creates a subdirectory for each
  of the fundamental elements: jobs, packages, source (which BOSH calls `src`), and blobs.
  
  ### <a id="source"></a> Populate the src directory ###
  
  
negative.code: * Each path to the corresponding file on a job VM is a value.
  
  The file paths that you provide for templates are relative to
  the `/var/vcap/jobs` directory on the VM.
  
  When you write:
  
  ~~~
  bin/ctl
  ~~~
  
  That is transformed at compile time, into:
  
  ~~~
  /var/vcap/jobs/<job_name>/bin/ctl
  ~~~
  
  In our example, we edit the `spec` files for the both the `web_ui` and `bg_worker` jobs.
