""" l10n_bumper.py
Updates a gecko repo with up to date changesets from l10n.mozilla.org.
Specifically, it updates l10n-changesets.json which is used by mobile releases.
This is to allow for `mach taskgraph` to reference specific l10n revisions
without having to resort to task.extra or commandline base64 json hacks.
