# Sets up an environment ready to build and run tests. For example, 'pw watch'
# should work in this environment.
#
# Usage: source bootstrap.sh

# Update submodules, initializing if necessary. This will pin all submodules to
# the committed revision so don't run this with uncommitted changes in a
# submodule. By convention, submodules are pinned to an upstream revision and
# any changes should be submitted upstream. Local changes to submodules are not
# carried long term, but patches waiting to land upstream may be applied
# manually.
git submodule update --init
