Usage: ${0##*/} [ options ]

   import Ubuntu releases and update default MAAS settings

   options:
      -i | --import-isos      Import the Ubuntu ISOs and update default
                              settings used for MAAS. (default)
      -u | --update-settings  Updates all profiles based on new settings
                              in /etc/maas/import_isos.

   The --import process downloads and imports a list of Ubuntu releases,
   adding the default MAAS settings for each of the profiles.  If a
   release has already been imported but is out of date, the updated ISO
   will be downloaded again and reimported.

   If the ISOs have already been imported, update-settings will update all
   the profiles within cobbler based on the modifications of
   /etc/maas/import_isos.

   Example:
    - ${0##*/} -i
