[Max Bowsher]

[r=allenap][bug=766149] New upstream snapshot (Use lazy hook installation with bzr >= 2.4; Correct regexp used for getting revno currently on edge); Add missing XB-Python-Version field to control, fixing incorrect installation path of the Python files.

Fix the package, which is currently totally broken due to installing the Python files in the incorrect directory.

Then, pull in a couple of upstream changes whilst we're rebuilding it anyway.

[Gavin Panella (allenap)]

I know almost nothing about the dirty work involved in packaging, but
a search led me to the following:

  The use of XB-Python-Version in the binary package paragraphs of
  debian/control file has been deprecated and should be removed in the
  normal course of package updates. It never achieved sufficient
  deployment to support it's intended purpose of managing Python
  transitions. This can be adequately accomplished by examining
  package dependencies.

  http://www.debian.org/doc/packaging-manuals/python-policy/ch-module_packages.html

Should you instead be using X-Python-Version?

If we were targetting Debian sid or Ubuntu natty, then yes. However this packaging is specifically using forms that are now considered deprecated in order to target Ubuntu >= lucid.

[Gavin Panella (allenap)]

Thanks for the explanation.

review: Approve

[Gavin Panella (allenap)]

Do you need someone to land this for you?

> Do you need someone to land this for you?

Currently yes, though Robert implied I could be given write access to the branch in bug 766149.

[Gavin Panella (allenap)]

Okay, set a commit message and I'll send it off.

[Gavin Panella (allenap)]

Max, I had to squish the commit message because PQM, bless its cotton socks, can't deal with more than a single line at a time.

[Max Bowsher (maxb)]

PQM hasn't been used on this branch before, and I now have commit access. Can you see any reason why I shouldn't just push these revisions at the branch directly?

[Gavin Panella (allenap)]

No, just land it then. Sorry for the bother!
