# For the docs and book build, we output the built sites as artifacts and cache them.
# A file containing the revision hash is output into the directory, so we can check
# if we need to rebuild and redeploy. If we detect an existing cached version, we check
# the revision and rebuild appropriately.

# Additionally, we output the paths that were rebuilt into docs-paths-updated and
# book-paths-updated, so that we can later trigger invalidations in cloudfront for
# the relevant paths.
