Items which still need to be done:

(for 0.2.0)

* Handle udeb packages correctly (entries go into
    dists/<dist>/<section>/debian-installer/<binary>/Packages instead of
    dists/<dist>/<section>/<binary>/Packages)

* Fix deb/udeb stuff in Audit_Packages (Packages.pm)

* Support tools for manipulating metadata (which really means 'anything
  stored in database files').

* Working support for Priority and Section data in Source records.

* Support rebuild-dbs (including invocation from rebuild-all).

* Hook support (or maybe 0.3.0) for generic hooks.

(for 0.3.0 or so)

* Support an external source for binary-all data (for example, snarfing it
  out of a Packages file from http.us.debian.org).

(unknown)

* Integrate with (or emulate) debsig-verify, to allow for verification of
  signed deb files (in addition to signed metadata).

* Some way to double-parse values in $archive (allowing the equivalent of
  relative path references from archive_dir, so that changes are reflected
  in all other paths by default).
