# The two checkouts reproduce the layout on a working machine: this repository sits at
# rust/margin-mail and the public margin repository beside it at python/margin, because
# package.json depends on margin-shared through a relative path. A token edit there is meant to
# show up in every Margin app at once, and a copy vendored here would defeat that.
