- per-framework, indicate extra dependencies we didn't alreayd have,
- add some external dependencies (e.g. for kidletime),
- Ashley Stone suggested a list of extra packages; add some of
  them -- getting the list complete requires also deciding what
  the list is *for*
- add note that the Debian section is kind of useless, since it
  installs so little -- you will need to manually discover all
  of the dependencies anyway.
