   * The package name.
   * The package's dependencies.
  -* The location where BOSH can find the binaries and other files that the package needs during compilation.

   Use your dependency graph to determine which dependencies belong in each spec.
   Your personal preferences and style as a developer also play a role here.
  
positive.code: 
  The path we provided for the `bg_worker` control script is
  `bin/ctl`.
  We know that BOSH will translate that into the full path `/var/vcap/jobs/bg_worker/bin/ctl`.
  
  Update the `spec` files for all the jobs in your release with the template names.
  
  
negative.code: 
  BOSH interprets the locations you record in the `files` section as being
  either in the `src` directory or in the `blobs` directory.
  (BOSH looks in `src` first.)
  When you add the actual blobs to a blobstore (see the next section),
  BOSH populates the `blobs` directory with the correct information.
  
  For packages that depend on their own source code, use the globbing pattern
  `<package_name>/**/*` to deep-traverse the directory in `src` where
  the source code will reside.
  
  Observe how these conventions are followed in the examples.
