Code review comment for lp:~allenap/launchpad/itch

utilities/update-sourcecode has stopped working with recent bzr installations from the beta PPA, because there is no longer any support for bzrlib with python 2.4. Thankfully this script runs fine with python 2.5 or 2.6. I chose 2.5 so that it will still run on Hardy. I also made it run with unbuffered stdin/stdout (-u) because otherwise there was no progress visible when running it via rocketfuel-get until it completed.
