Examples of bzr-builddeb?

[John Barstow]

I thought I'd try my hand at packaging bzr-tfs into a PPA for Ubuntu,
but I'm running into issues. Is there a good example of bzr-builddeb
being used anywhere? The existing documentation isn't really
comprehensive.

I thought it would be straightfoward to package in builddeb 'native'
mode but that seems to fail - it keeps complaining that quilt can't
find the orig.tar.gz file (which shouldn't need to exist in native
mode, unless I'm very confused).

Any suggestions or pointers to examples would be much appreciated; I
want to use the packaging exercise for both python-ntlm and bzr-tfs as
my gateway to becoming an Ubuntu developer.
