Script should do the following

• Validate the links of the podcasts (whether they are broken)
• Validate the order of the podcasts in each category (and also categories)

Break the build when either of the above validations fail

updater.py on confined_target_dirs:

  # ... In the example, the client has chosen '', which is
  # interpreted as no confinement.  In other words, the client can download
  # targets from any directory or subdirectories.  If the client had chosen
  # 'targets1/', they would have been confined to the '/targets/targets1/'
  # directory on the 'http://localhost:8001' mirror.
