# dist.build must be the name of a target which triggers the

# intention is that it be one of (o0, o1, o2, o3, os, oz), each of
# which uses like-named -Ox optimization level flags. The o2 target
# provides the best overall runtime speeds. The oz target provides
# slightly slower speeds (roughly 10%) with significantly smaller WASM
# file sizes. Note that -O2 (the o2 target) results in faster binaries
# than both -O3 and -Os (the o3 and os targets) in all tests run to
