Really, that's probably the most valuable part of this, even if not
the most interesting -- having a sane way to unpack source packages to
the *actual* working tree makes it much more sane to do analysis of the
source, hack on it, whatever.

And something that works for a pure tarball of a .git directory all the
way to unpacked .c files seems like it should certainly be general enough
to achieve that. That seems (to me) like it means:

	- keep the perl module structure Joey's created and expect to
	  use it with other ways of dealing with patches internally to a
	  source package (quilt, bzr, darcs, whatever)

	- finalise the remaining tweaks: drop the bracketed "(git)" from
	  the Format: field and handle it some other way? add a
	  Source-Depends: field?

It seems... remarkable that making the source package format more
dependent on the revision control system would make NMUers and others
more able to ignore it.

The remaining big question seems to be whether to have Debian source
packages include the working tree directly so people don't need git to
get at it; but that seems to me something that can be decided by policy
mechanisms outside dpkg.

So, afaics, the dpkg maintainers should:

	- add Source-Depends:   (I'm biassed :)
	- upload dpkg with modular support to unstable
	- upload git/bzr support as part of either dpkg or the git/bzr
	  packages, with appropriate autogenerated Source-Depends: 

and ftpmaster should start accepting git/bzr source packages to
experimental so we can get some practical experience with the format, and
decide whether to have .git.tgz or .git+.orig+.xdelta .tgz's or whatever to

I'd expect we'd either wait for lenny to release, or an updated dpkg with
Format:3.0 support to be in an etch point release before accepting such
packages in unstable either way, but better to get started sooner, afaics.
