A short while back I wrote a broker for Weblate. I didn't want to submit
it before the Bitbucket hook was actually available on Weblate too. But
it is now!
If you need to make any changes to it, I'd appreciate it if you submit
pull requests I can pull in. Also, feel free to point people to the
project/repository for an example of a broker that's out in the open.
