-    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.
