Heh:

  http://git.debian.org/?p=tools-release/release.git;a=blob;f=scripts/dep-graph;h=7ad1c0ad164ff38ad890a7860c9d50dbe82479e8;hb=HEAD

Which reminds me to ask: do you know about apt_pkg.ParseDepends? It does
something similar:

  >>> pprint.pprint(apt_pkg.ParseDepends(p.Section['Depends']))
  [[('dcoprss', '4:3.5.9-2', '>=')],
   [('kdenetwork-kfile-plugins', '4:3.5.9-2', '>=')],
   [('kdict', '4:3.5.9-2', '>=')],
   [('kdnssd', '4:3.5.9-2', '>=')],
   [('kget', '4:3.5.9-2', '>=')],
   [('knewsticker', '4:3.5.9-2', '>=')],
   [('kopete', '4:3.5.9-2', '>=')],
   [('kpf', '4:3.5.9-2', '>=')],
   [('kppp', '4:3.5.9-2', '>=')],
   [('krdc', '4:3.5.9-2', '>=')],
   [('krfb', '4:3.5.9-2', '>=')],
   [('ksirc', '4:3.5.9-2', '>=')],
   [('kwifimanager', '4:3.5.9-2', '>=')],
   [('librss1', '4:3.5.9-2', '>=')]]

So it returns a 3-tuple instead of a dict, which may or may not be more
convenient, I'm just curious if you knew about it and designed it
differently on purpose.

As an aside, something seems to be broken on your branch at the moment?:

  >>> x['Depends']
  'dcoprss (>= 4:3.5.9-2), kdenetwork-kfile-plugins (>= 4:3.5.9-2), kdict (>= 4:3.5.9-2), kdnssd (>= 4:3.5.9-2), kget (>= 4:3.5.9-2), knewsticker (>= 4:3.5.9-2), kopete (>= 4:3.5.9-2), kpf (>= 4:3.5.9-2), kppp (>= 4:3.5.9-2), krdc (>= 4:3.5.9-2), krfb (>= 4:3.5.9-2), ksirc (>= 4:3.5.9-2), kwifimanager (>= 4:3.5.9-2), librss1 (>= 4:3.5.9-2)'
  
  >>> pprint.pprint(x.relations['depends'])
  [[{'name': 'dcoprss', 'version': None}],
   [{'name': 'kdenetwork-kfile-plugins', 'version': None}],
   [{'name': 'kdict', 'version': None}],
   [{'name': 'kdnssd', 'version': None}],
   [{'name': 'kget', 'version': None}],
   [{'name': 'knewsticker', 'version': None}],
   [{'name': 'kopete', 'version': None}],
   [{'name': 'kpf', 'version': None}],
   [{'name': 'kppp', 'version': None}],
   [{'name': 'krdc', 'version': None}],
   [{'name': 'krfb', 'version': None}],
   [{'name': 'ksirc', 'version': None}],
   [{'name': 'kwifimanager', 'version': None}],
   [{'name': 'librss1', 'version': None}]]
