python reposado更新通知：报告在repo_sync运行之间更改了Apple产品

reposado update notification: reports changed Apple products between repo_sync runs

Checks the current list of updates versus the previous list of updates and
reports on the changes. Run this script after your repo_sync run to see the
changes between syncs. You can then hand this report off in email if you wish.

For example:

  repo_sync
  reponotify.py | mail -Es 'Reposado updates' [e-mail]

Note that this script requires write permission in the UpdatesRootDir
directory of your reposado. This is so that it can write the tracking file
that is used between runs to compute the difference in update lists.

Note also it needs access to the "reposadocommon" Python library. This means
you probably want to place it in the "code" directory of your reposado
installation.
