Repo Pull

repo_pull.py pulls multiple change lists from a Gerrit code review website. A user may specify a query string and repo_pull.py will pull the matching change lists.

For example, to pull the repo-pull-initial-cl topic from AOSP, run this command:

repo_pull.py pull 'topic:repo-pull-initial-cl' \
    -g https://android-review.googlesource.com
