Merge lp:~jml/launchpad/visible-dependencies into lp:launchpad

[Jonathan Lange]

Add 'make lp-clustered.svg' target to generate import dependency information.

This branch adds a bunch of make targets to produce package dependency graphs. It means that we'll need a new dependency in launchpad-developer-dependencies.

To test:
  $ sudo apt-get install snakefood
  $ make lp-clustered.svg

And then view lp-clustered.svg or lp-clustered.dot in your favourite viewer. Mine is dotviewer from pypy.

Run 'make clean' to watch the created files disappear.

The file lp-sfood-packages contains a list of the packages that I consider meaningful enough to appear on the dependency chart. It has to be reverse alphabetical order to give valid results.

[Eleanor Berger (intellectronica)]

I aired a concern about having to update the list of packages manually, but since we both couldn't think of a better solution we agreed that this better land, and that it's worth thinking whether a better, dynamic solution is possible.
