* Set up for DTSAs

  - Auto moderation of developer signed mails to -announce.

  - sndadvisory should remove TODO lines from the list file since the
    advisory is complete

  - merge sndadvisory into dtsa script?

  - web DTSA pages should be built on the fly using the metadata in DTSA/
    so we don't have to update things in two places when making a change,
    and so releasing a DTSA does not involve copying html files around

  - The dtsa script should have support for updating the list file
    when running it on an advisory that it's already been run on before.
    This would facilitate issuing asvisories, which often takes a few runs
    before the final one is sent. Alternatively, get rid of the DTSA/list
    file (do we need it for anything really?)

* Merge stuff into security.debian.org. Long term, but we need to keep in
  mind that the current archive setup is just to get bootstrapped.
