# relative to the repo root.

# --optimize tree-shakes the runtime so only the reachable functions -- and only
# the WASI imports they actually reach -- ship. These are the smallest programs
# in the examples, so it is also the largest difference: without it each module
# carries the whole runtime and is ~40x bigger.
