dupload TODO
------------

* Improve hook system:
  - Rewrite several dupload features, such as announcements, as hooks.
  - Make it possible to run perl modules in addition to shell commands.

* Refactor uploader methods into Perl modules.

* Add new uploader methods:
  - FTP via HTTP proxy.
  - SFTP.

* Switch to use libdpkg-perl Perl modules.

* Add a new command to generate DAK or archive specific control commands,
  possible names, could be drecall, dacl, etc.

* Use the dpkg vendor system to select default configurations and hosts.
  - Create new /etc/dupload.conf.d/<vendor>.conf style loading, perhaps?
  - dinstall_run could be implicitly set for Debian vendor.
  - Improve mailto/mailtx mess, it should be vendor and/or host specific,
    not a global hardcoded handling thing.

* Add archive attribute information so that additional checks or features
  can be enabled on those.

* Think about switching from a perl "config" to a proper declarative config
  format.

* Add functional tests:
  - Other methods (ftp, http, https).
  - Reupload (no-op, forced).
