Thanks Joey for posting that.
Ok, now for some fun stuff.
In the transcript, it is mentioned that I wrote dbs. It is a multi-tarball,
multi-patch system, that is currently in use by several pkgs. However, it has
its drawbacks, the 2 most glaring that it hides the source in subtrees, all
packed up, and that it doesn't extract into <pkg>-<ver> directly.
So, I decided to do something about that finally. Below is an example dsc
format that I have come up with.
===
Source: xawtv
Format: 2.0
Version: 3.07-2
Binary: xawtv, fbtv, radio, streamer, webcam, xawtv-tools
Maintainer: Adam Heath <doogie@debian.org>
Architecture: any
Standards-Version: 3.1.1
Build-Depends: debhelper, autoconf, xlib6g-dev, xaw3dg-dev, libjpeg62-dev, xbase-clients

You'll note the addition of 3 fields(Format, Patches, and Tarballs), and the
different files specified for the files field. The existance of a Format
field can be used to see that this is a new format source package. Currently,
my script doesn't use that. It looks for a .diff.gz, and if found, assumes an
old format.
The current format has 3 files that are distributed with a source
package. The .orig.tar.gz, a .diff.gz, and a .dsc. With this new format, it
increases that count by 1. I couldn't see a way around this however, while
still keeping with my intended outcome.
The entries listed in the Patches field are contained in the .patches.tar.gz
file. Those listed in the Tarballs field are listed in the .tarballs.tar.gz
file. The files listed are extracted in the sort order produced by ls, so
naming is important. There is also no distinction between upstream and debian
only patches.
I currently have a script that can parse this new format, and extract both old
and new format archives. It doesn't yet support building a .dsc from a
directory. Also, I currently only support tar and gz, with plans for ar, zip,
jar, Z, bz, bz2, and whatever else exists that we can use in Debian.
A transcript of the scripts output follows:
===
$ ./unpack xawtv_3.07-2.dsc
Extracting xawtv in xawtv-3.07.
Extracting tarball debian.tar.gz.
Applying patch 000_fbtv_fhs.diff.
Applying patch 001_i2c_header_fix.diff.
Applying patch 002_Makefile.in.sanity.diff.
Applying patch 003_autoconf_parallel_compile.diff.
