This looks good, thanks!

Awesome. Maybe you could help for example the maintainer of
git-hgbuildpackage to use python-debian, so that all the code is on
one place.

BTW, I tried your example
/usr/share/doc/python-debian/examples/packages/grep-maintainer and it
doesn't work:

$ ./grep-maintainer "stefano"
Traceback (most recent call last):
  File "./grep-maintainer", line 26, in ?
    if maint_RE.search(pkg['maintainer']):
TypeError: list indices must be integers


so please apply this patch to get it work:

diff -r bb09c7963ded grep-maintainer
--- a/grep-maintainer   Mon Oct 29 12:42:59 2007 +0100
+++ b/grep-maintainer   Mon Oct 29 12:48:08 2007 +0100
@@ -23,6 +23,7 @@ except:

 packages = PackageFile('/var/lib/dpkg/status')
 for pkg in packages:

+    pkg = dict(pkg)
+    if "maintainer" in pkg and maint_RE.search(pkg['maintainer']):
         print pkg['package']


Now it works:

$ ./grep-maintainer "stefano"
